How To Change Inner Tie Rods: Complete Step-by-Step Replacement Guide

Replacing a worn inner tie rod requires lifting the vehicle safely, disconnecting the outer tie rod end, removing the steering rack bellows boot, and unthreading the inner tie rod joint using a specialized inner tie rod tool tool sleeve. Torquing the replacement shaft precisely to OEM specifications (typically 50 to 75 ft-lbs) and applying medium-strength threadlocker prevents rack damage and hardware loosening. Following installation, performing a baseline measurement check ensures drivability until a professional four-wheel laser alignment is completed.

Pre-Service Diagnostics, Tools, and Safety Protocols

Before raising the vehicle, confirm that the inner tie rod is the actual root cause of steering instability. Common symptoms of a failing inner tie rod include a distinct clunking or popping noise when turning the steering wheel, excessive free play (slop) in the steering wheel, uneven tire tread wear across the inner or outer shoulders, and a drifting or pulling sensation at highway speeds.

To diagnose an inner tie rod accurately, jack up the front end of the vehicle, support it on jack stands, and grab the tire at the 3 o'clock and 9 o'clock positions. Wiggle the wheel back and forth horizontally. If you feel loose play, observe whether the outer tie rod ball joint moves independently of the steering knuckle. If the outer joint remains rigid while the inner shaft moves inside the steering rack bellows boot, the internal ball joint of the inner tie rod is severely worn and requires immediate replacement.

Essential Equipment & Materials Checklist

• Primary Hand Tools: Heavy-duty floor jack, 2-ton (or higher) rated jack stands, wheel chocks, 1/2-inch drive breaker bar, torque wrench (rated 10–150 ft-lbs), metric open-end wrench set (17mm to 24mm), needle-nose pliers, and locking pliers.
• Specialized Automotive Tools: Inner tie rod removal tool kit (tube sleeve type with interchangeable crowsfoot/c-shaped adapters), tie rod end puller or pickle fork, and boot clamp pliers (ear-clamp pliers).
• Chemicals & Consumables: Medium-strength threadlocking compound (e.g., Blue Threadlocker 242), NLGI Grade 2 synthetic chassis grease, penetrating oil (e.g., PB Blaster or WD-40 Specialist), heavy-duty replacement boot clamps (or stainless steel zip ties), and shop towels.
• Prerequisite Knowledge & OEM Standards: Familiarity with front suspension torque values, rack-and-pinion design, metric fastener sizing, and basic vehicle lifting safety points.
• Project Benchmarks: Estimated cost for DIY parts ranges from $40 to $120 per side. Estimated repair time is 1 to 2 hours per side for home mechanics, plus professional alignment time.

Step-by-Step Inner Tie Rod Replacement Procedure

Step 1: Vehicle Preparation and Safety Elevation

Park the vehicle on a clean, level concrete surface. Engage the parking brake firmly and place wheel chocks behind the rear tires to prevent rolling.

1. Loosen the lug nuts on the front wheel of the side you are servicing by one-half turn using a breaker bar while the vehicle is still on the ground.
2. Position the floor jack under the manufacturer's designated frame lift point or subframe crossmember, and raise the front of the vehicle until the tires clear the ground by at least 4 to 6 inches.
3. Lower the vehicle securely onto jack stands. Never rely solely on a hydraulic jack while working under a vehicle.
4. Fully remove the lug nuts and pull the wheel assembly away from the hub to gain unobstructed access to the wheel well and steering components.

Warning: Never place any part of your body under a vehicle supported only by a hydraulic jack. Verify that the jack stands are positioned on solid structural steel and that the vehicle cannot shift before beginning mechanical teardown.

Step 2: Measure Baseline Alignment and Disconnect Outer Tie Rod

Maintaining near-accurate toe alignment during assembly prevents severe tire scrub on your drive to the alignment shop.

1. Clean the exposed threads of the outer tie rod jam nut with a wire brush, and spray the jam nut and outer tie rod ball joint stud generously with penetrating oil.
2. Using a tape measure or digital vernier caliper, measure the exact distance from a fixed point on the steering rack or inner tie rod shaft to the center of the outer tie rod ball joint. Record this measurement on paper. Alternatively, count and record the exact number of threads exposed between the jam nut and the outer tie rod end.
3. Hold the inner tie rod wrench flat with an open-end wrench while loosening the jam nut clockwise (when viewed from the wheel well) by approximately one-quarter turn. Do not back the nut off significantly yet.
4. Remove the cotter pin from the outer tie rod castle nut (if equipped). Unbolt the castle nut or prevailing torque nut from the steering knuckle ball joint stud.
5. Attach a dedicated tie rod puller tool onto the steering knuckle steering arm and press the tapered stud out of the knuckle arm. If using a hammer, strike the side of the heavy cast boss on the steering knuckle sharply to release the taper lock.
6. Unthread the outer tie rod end counterclockwise from the inner tie rod shaft while keeping track of the exact number of full 360-degree rotations. Store the outer tie rod end nearby.
7. Unthread and remove the jam nut from the old inner tie rod shaft.

Pro-Tip: Take a photograph of the thread engagement before removing the jam nut. Combining a physical caliper measurement, thread count, and photo reference ensures your temporary manual alignment stays within 1/16th of an inch of its original setting.

Step 3: Remove Steering Rack Bellows Boot

The rubber bellows boot protects the internal rack-and-pinion assembly from water, dirt, and road debris. It must be detached carefully to avoid tearing the rubber.

1. Locate the outer boot clamp near the tie rod shaft. Remove it by unhooking the spring tension clip with pliers or cutting the factory squeeze clamp.
2. Locate the inner boot clamp attached around the larger diameter of the aluminum steering rack housing. Snip the OEM metal ear-clamp using side cutters or a small flathead screwdriver.
3. Locate the small breather tube connected to the bellows boot (present on many hydraulic rack systems). Gently pull the flexible vacuum hose off its nipple on the rubber boot.
4. Slide the rubber bellows boot off the inner tie rod shaft entirely. Inspect the internal surface of the boot for power steering fluid leaks.

Warning: If power steering fluid pours out of the bellows boot when removed, the internal oil seals of the steering rack housing have failed. Replacing the inner tie rod will not fix a hydraulic leak; the entire rack-and-pinion assembly must be replaced or remanufactured.

Step 4: Unseat and Extract the Inner Tie Rod Assembly

The inner tie rod features a large ball-and-socket joint threaded directly into the end of the steering rack gear shaft.

1. Inspect the inner tie rod housing joint for mechanical locking mechanisms. Some manufacturers use a fold-over lock washer, a setscrew, or a roll pin. If a lock washer is installed, use a punch and hammer to flatten the metal tabs folded over the hex flats.
2. Select the correct size adapter ring from your inner tie rod tool kit that fits snugly over the hex housing or dual flat spots of the inner tie rod ball joint.
3. Slide the adapter ring onto the joint, then slide the long hollow inner tie rod tool tube over the entire shaft until it engages with the adapter ring.
4. Attach a 1/2-inch drive breaker bar or ratchet to the end of the hollow tool tube.
5. Hold the steering rack shaft steady if necessary, and turn the tool counterclockwise to break the inner tie rod joint free from the rack shaft.
6. Once loosened, unthread the inner tie rod completely by hand and remove the old assembly from the vehicle along with its lock washer (if applicable).

Step 5: Prepare and Install the New Inner Tie Rod

Proper surface preparation and chemical locking ensure the new inner tie rod remains locked to the rack shaft throughout the service life of the vehicle.

1. Clean the internal threads of the steering rack shaft using a clean lint-free shop towel and brake cleaner to remove old grease and threadlocking residues.
2. Check the new inner tie rod against the old component to verify overall length, thread pitch on both ends, and socket design match precisely.
3. Install a new fold-over lock washer onto the threaded male stud of the new inner tie rod (if specified by the vehicle manufacturer).
4. Apply 2–3 drops of medium-strength blue threadlocking compound to the male threads of the inner tie rod joint.
5. Thread the inner tie rod into the steering rack housing by hand until it seats fully against the rack face to prevent cross-threading.
6. Slide the inner tie rod tool tube back over the shaft, attach your torque wrench, and torque the joint to the manufacturer's exact specification (typically between 50 and 75 ft-lbs).
7. If using a fold-over lock washer, use a long drift punch to carefully bend the washer tabs over the wrench flats of the joint housing.

Pro-Tip: Apply a thin film of NLGI Grade 2 lithium grease to the actual ball-and-socket joint if it is not pre-greased from the factory. Additionally, apply a tiny amount of grease to the outer metal ridge where the bellows boot seats to allow the boot to rotate freely without twisting during future alignment adjustments.

Step 6: Secure Bellows Boot and Reattach Outer Tie Rod Joint

1. Slide the rubber bellows boot back onto the inner tie rod shaft, positioning the large end over the main steering rack housing and the small end into its designated groove on the shaft.
2. Reattach the small breather tube to the boot nipple if applicable.
3. Secure the inner base of the boot using a new metal ear-clamp or a heavy-duty nylon cable tie pulled tight with pliers. Secure the outer boot end with its spring clamp or zip tie.
4. Thread the jam nut back onto the new inner tie rod shaft past the point where the outer tie rod will seat.
5. Thread the outer tie rod end onto the shaft, counting the exact number of turns recorded during disassembly.
6. Insert the outer tie rod ball joint stud into the steering knuckle arm hole.
7. Thread on the castle nut or locknut. Torque the nut to specification (typically 35 to 55 ft-lbs). If using a castle nut, tighten slightly further until the cotter pin hole aligns, then insert a new stainless steel cotter pin and bend the legs around the stud.
8. Snug the jam nut firmly against the outer tie rod body using two open-end wrenches.

Step 7: Perform Baseline Alignment and Final Torque Check

1. Take a final measurement from your reference point to the center of the outer tie rod stud using your caliper or tape measure. Adjust the inner shaft position via the jam nut until it matches your initial baseline reading exactly.
2. Mount the wheel back onto the wheel hub and hand-tighten the lug nuts.
3. Lower the floor jack until the tire touches the ground lightly, then torque the lug nuts in a star pattern to the vehicle's factory specification (typically 80 to 110 ft-lbs).
4. Lower the vehicle completely and remove the floor jack and wheel chocks.

Torque Specifications and Component Tolerances

The following technical matrix provides standard reference ranges for front-end steering components across passenger vehicles, light trucks, and crossovers. Always cross-reference these metrics with your specific vehicle service manual.

Common Steering System Failure Modes and Field Remedies

Steering Rack Shaft Spins During Inner Tie Rod Removal

• Root Cause: The internal rack-and-pinion helical gear mesh lacks sufficient friction to counteract the breakaway torque applied by the breaker bar, causing the smooth rack bar to turn inside the housing.
• Actionable Fix: Turn the steering wheel all the way to the lock position corresponding to the side you are working on (e.g., turn left fully for the driver-side tie rod). This exposes more of the rack shaft and grounds the internal mechanical stop against the rack housing, preventing rotation. Alternatively, use an open-end wrench on the flat surface machined into the rack shaft (if equipped) to hold counter-torque.

Persistent Steering Wheel Off-Center Post-Installation

• Root Cause: The thread engagement count or physical measurement distance varied by even a fraction of a millimeter, shifting the baseline toe-in or toe-out value of the front wheels.
• Actionable Fix: Adjust both inner tie rods in equal, opposite increments. Loosen both jam nuts. To shift the steering wheel to the right, lengthen the left tie rod assembly (turn shaft out) and shorten the right tie rod assembly (turn shaft in) by identical 1/8th-turn increments until the wheel centers during straight-line driving. Schedule a professional alignment immediately.

Torn or Slipping Steering Rack Bellows Boot

• Root Cause: Reusing an old, dry-rotted rubber boot, or failing to apply grease to the inner tie rod neck, causing the rubber boot to twist and tear when the technician turns the shaft during toe adjustments.
• Actionable Fix: Replace damaged boots immediately with a new neoprene OEM bellows boot. Always apply a thin coating of silicone grease or white lithium grease to the smooth metal shaft where the small end of the boot clamps down, enabling the inner tie rod to rotate inside the boot clamp during alignment work without twisting the rubber.

persistent Knocking Noise After Replacing Inner Tie Rod

• Root Cause: The outer tie rod end ball joint, lower control arm ball joint, or sway bar end link is also worn out, or the inner tie rod housing was not torqued adequately to the rack shaft.
• Actionable Fix: Re-torque the inner tie rod joint to specification using the tube tool. Perform a full suspension check by using a pry bar under the control arm and sway bar links to isolate secondary mechanical looseness in adjacent joints.

Frequently Asked Questions

Can I replace an inner tie rod without buying a special tool?

While it is technically possible on a few select vehicles using large pipe wrenches or narrow adjustable wrenches, access inside the tight wheel arch and unibody frame pocket is usually restricted. Using pipe wrenches risks rounding off the joint housing, galling the polished steering rack shaft, or applying improper torque. Renting or purchasing a dedicated master inner tie rod tool set with a hollow sleeve and crowsfoot adapters ensures you can achieve accurate torque specs without damaging the rack.

Do I need a wheel alignment immediately after replacing an inner tie rod?

Yes, a professional wheel alignment is mandatory after replacing any tie rod component. Even if you carefully count threads and match pre-repair measurements down to the millimeter, subtle manufacturing variances between new and old parts alter your vehicle's toe angle. Driving without a professional laser alignment leads to accelerated tire tread scrubbing, reduced fuel efficiency, and compromised emergency handling within just a few hundred miles.

How do I determine whether the inner tie rod or outer tie rod is failing?

Raise the vehicle and grab the front tire at 3 o'clock and 9 o'clock. Have an assistant wiggle the wheel back and forth while you squeeze the rubber boot of the inner tie rod and watch the outer tie rod end joint. If you feel internal play inside the rubber boot, the inner tie rod socket is shot. If you see the outer tie rod stud moving up and down or side-to-side inside its cast arm socket, the outer tie rod is bad.

Should I replace inner tie rods in pairs?

Replacing tie rods in pairs (both left and right sides simultaneously) is highly recommended. Both sides experience the exact same mileage, road impact cycles, and degradation over time. Replacing both sides together saves money by requiring only one post-repair wheel alignment fee rather than paying for two separate alignments weeks or months apart.

Professional Steering & Suspension Diagnostics

Restoring precise steering control and eliminating unsafe mechanical play requires quality components, accurate torque execution, and exact alignment calibration. If you encounter frozen steering rack threads, hydraulic fluid leaks inside the bellows boot, or severe rack internal movement, consult a certified ASE master technician to evaluate your complete steering assembly.
