How To Change Inner Tie Rod: Complete Step-by-Step DIY Replacement Guide
Replacing a worn inner tie rod restores steering precision, prevents premature tire wear, and eliminates loose steering play by renewing the critical mechanical link between the steering rack and the outer tie rod. Executing this repair requires a specialized inner tie rod tool, precise torque application, and a mandatory professional wheel alignment immediately afterward.
Pre-Operation & Equipment Checklist
Replacing an inner tie rod is a moderately advanced mechanical procedure that demands patience, safety compliance, and the right tooling. The inner tie rod resides beneath a protective rubber bellows boot, hidden from direct view, meaning you must dismantle the wheel assembly and outer tie rod before accessing the target component.
Essential Gear, Tools, and Materials:
- Heavy-duty floor jack and certified jack stands (never rely on a hydraulic jack alone)
- Lug wrench and socket set (metric sizes ranging from 10mm to 22mm)
- Torque wrench capable of 20 to 100 ft-lbs
- Universal inner tie rod removal tool (crowfoot style or pass-through tube style)
- Needle-nose pliers and diagonal cutters (for cotter pins or clamp removal)
- Replacement inner tie rod assembly, new rubber bellows boot clamps (or zip ties if specified), and a fresh cotter pin if applicable
- Thread-locking fluid (medium-strength, blue Loctite)
- Penetrating oil (such as PB Blaster or WD-40 Specialist)
Prerequisite Knowledge and Technical Standards:
- Basic familiarity with suspension geometry, torque specifications, and threaded fasteners.
- Awareness that changing any steering component alters vehicle alignment toe settings, requiring professional calibration post-repair.
Estimated Time and Budget Benchmarks:
- Duration: 1.5 to 3 hours depending on rust severity and suspension layout.
- Cost: $40 to $120 for parts and specialized tool rental, compared to $250 to $500 at a professional repair shop.
Step-by-Step Replacement Workflow
Step 1: Vehicle Preparation and Wheel Removal
Secure the vehicle on level ground, engage the emergency brake, and loosen the lug nuts on the affected side by a quarter-turn. Elevate the vehicle securely using a hydraulic floor jack and lower it onto a rated jack stand positioned at a designated factory pinch weld or frame point. Remove the lug nuts entirely and take off the front wheel to expose the brake rotor, steering knuckle, and suspension components.
Warning: Never place any portion of your body under a vehicle supported solely by a hydraulic jack. Always verify the vehicle rests securely on solid jack stands before proceeding.
Step 2: Disconnecting the Outer Tie Rod
Locate the outer tie rod end where it connects to the steering knuckle. Remove any cotter pin passing through the castle nut at the stud. Use an appropriately sized box-end wrench or socket to remove the castle nut. Separate the tapered stud of the outer tie rod from the steering knuckle using a tie rod separator tool or a sharp hammer blow to the side of the knuckle housing. Once separated, unscrew the outer tie rod from the inner tie rod, counting the exact number of full turns it takes to remove it.
Pro-Tip: Record the exact number of rotations required to unscrew the outer tie rod. Thread the replacement outer tie rod onto the new inner tie rod using this exact count to keep your alignment close enough for a safe drive to the alignment shop.
Step 3: Removing the Steering Bellows Boot
Locate the rubber steering rack boot (bellows) that shields the inner tie rod joint from road debris and moisture. Cut or unclip the large outer clamp securing the boot to the steering gear housing, and the smaller inner clamp securing it to the tie rod shaft. Slide the boot down the shaft toward the outer end and pull it off the steering gear housing. Inspect the boot for tears or dry rot; replace it immediately if compromised.
Step 4: Extracting the Worn Inner Tie Rod
Turn the steering wheel fully toward the side you are working on to extend the steering rack shaft outward, providing maximum clearance. Slide the universal inner tie rod removal tool over the inner tie rod shaft, sliding it all the way down until the socket securely grips the flat or hexagonal drive surfaces of the inner tie rod joint housing. Attach a half-inch breaker bar or ratchet to the tool and turn counter-clockwise to break the factory torque loose. Once unseated, spin the old inner tie rod out by hand alongside its washer.
Step 5: Installing the New Inner Tie Rod
Clean the exposed threads of the steering rack thoroughly using a wire brush and brake cleaner. Apply a few drops of medium-strength thread-locking fluid onto the male threads of the new inner tie rod. Thread the new inner tie rod onto the steering rack by hand to ensure the threads engage smoothly without cross-threading. Use the inner tie rod tool and a torque wrench to tighten the component to the manufacturer's precise specification, typically ranging from 50 to 75 ft-lbs depending on vehicle make and model.
Step 6: Reinstalling Bellows, Outer Tie Rod, and Wheel
Slide the rubber bellows boot back over the inner tie rod and position its seating lips securely into the grooves on the steering gear housing and tie rod shaft. Secure both ends with new metal clamp rings, crimping them tightly with dedicated boot pliers. Thread the outer tie rod back onto the inner tie rod using your previously recorded rotation count. Insert the outer tie rod stud into the steering knuckle, install the castle nut, and torque it to factory specifications. Install a new cotter pin through the stud hole if applicable, remount the wheel, lower the vehicle, and torque the lug nuts to specification.

Common Steering System Failures and Field Fixes
Root Cause: Stripped or rounded housing flats during removal due to an ill-fitting wrench.
- Actionable Fix: Stop immediately and switch to a dedicated crowfoot pass-through socket designed specifically for inner tie rod geometry rather than using open-ended adjustable wrenches.
Root Cause: Steering rack slippage or internal damage when applying torque to the new inner tie rod.
- Actionable Fix: Never use the internal steering rack stops to counter high torque loads. Have an assistant hold the opposite wheel or use locking pliers gently on the rack housing if permitted by the manufacturer.
Root Cause: Severe steering pull or crooked steering wheel after reassembly.
- Actionable Fix: Understand that manual turn-counting is only an approximation. Schedule a professional four-wheel alignment immediately to prevent rapid tread wear and unsafe handling dynamics.
Frequently Asked Questions
Can I drive my car without getting an alignment after replacing an inner tie rod?
Driving short distances to a local tire shop is generally acceptable if you carefully matched the thread count during reassembly. However, you must schedule a professional alignment immediately afterward because even a microscopic shift in tie rod length drastically alters your vehicle toe angle, causing rapid tire wear and unpredictable steering response.
How do I know if my inner tie rod is bad compared to the outer tie rod?
Jack up the vehicle, grasp the tire at the 3 o'clock and 9 o'clock positions, and rock it back and forth while observing the back of the wheel. If you see movement or feel play at the outer joint, the outer tie rod has failed. If the play originates deep underneath the rubber boot near the center of the vehicle while the outer joint remains firm, the inner tie rod requires replacement.
Do inner tie rods come with new rubber boots?
Most aftermarket inner tie rod replacements do not include the rubber bellows boot. You must inspect your existing boot during disassembly and reuse it if it remains pliable and un-torn. If the boot shows signs of cracking, splitting, or dry rot, purchase a replacement boot separately before starting the repair.
Is it necessary to use thread-locking fluid on inner tie rods?
Yes, applying medium-strength thread-locking fluid to the threads that screw into the steering rack is standard industry practice. The constant vibration and mechanical feedback from the road surface can cause un-locked fasteners to back out over time, leading to a complete loss of steering control.
Ensure your vehicle handles safely and predictably by scheduling a professional wheel alignment immediately after completing your inner tie rod replacement. Book your post-repair calibration appointment today to protect your tire investment and maintain optimal directional stability.
