Learn How to Replace an Inner Tie Rod

Understanding Inner Tie Rod Basics and When Replacement Is Needed

An inner tie rod is a critical steering component that connects your vehicle's steering rack to the outer tie rod end. This small but essential part allows your wheels to turn left and right when you rotate the steering wheel. The inner tie rod consists of a threaded rod with a ball joint at the end that connects to the steering knuckle assembly through the outer tie rod.

Inner tie rods wear out over time due to constant movement and exposure to road conditions. Common signs that replacement may be necessary include a loose or clunky feeling in the steering wheel, uneven tire wear, vehicle pulling to one side during driving, or a clicking sound when turning the wheel. You might also notice the steering wheel feels less responsive than normal, or there may be visible play in the wheel when you grasp it at the 3 and 9 o'clock positions.

Different vehicle makes and models have varying tie rod designs. Some vehicles use sealed tie rods that cannot be repaired, while others have serviceable designs. Checking your vehicle's service manual will tell you whether your particular model uses replaceable inner tie rods or if the entire steering rack assembly must be replaced. The cost of replacement varies significantly based on your vehicle type, ranging from $200 to $600 per side for parts and labor at professional shops.

Temperature extremes, salt exposure on roads during winter months, and hitting potholes or curbs can accelerate tie rod wear. Regular vehicle maintenance and inspections every 50,000 miles can catch worn tie rods before they create safety concerns. Worn tie rods affect your vehicle's wheel alignment and can cause premature tire wear if left unaddressed.

Practical Takeaway: Listen for unusual steering noises and monitor how your steering wheel feels during routine driving. If you notice changes in responsiveness or steering play, have the tie rods inspected before the wear becomes severe.

Tools and Materials You'll Need for the Job

Replacing an inner tie rod requires specific tools to safely remove the old component and install the new one properly. Having the correct tools makes the job significantly easier and reduces the risk of damaging other steering components. Basic hand tools needed include wrenches in various sizes (typically 14mm, 15mm, 16mm, and 17mm depending on your vehicle), a socket set, a breaker bar for loosening stubborn fasteners, and screwdrivers.

Specialized steering tools are particularly important for inner tie rod replacement. A tie rod removal tool, also called a tie rod puller or separator, helps disconnect the ball joint from the steering knuckle without damaging the joint. This tool applies even pressure around the ball joint, preventing the kind of damage that can occur when using a hammer or improper techniques. A 36mm hex wrench or inner tie rod socket is also necessary to loosen the tie rod from the steering rack, as these components use larger fasteners.

You'll need a jack and jack stands to safely lift your vehicle and support it while working underneath. Never work under a vehicle supported only by a jack. Two jack stands rated for your vehicle's weight provide a secure working platform. A creeper or mechanic's stool helps you work comfortably while under the vehicle. Wheel chocks prevent the vehicle from rolling unexpectedly.

Materials include a replacement inner tie rod assembly, which should match your vehicle's exact year, make, and model. Some technicians prefer applying a small amount of anti-seize compound to the threads of the new tie rod, though this depends on your vehicle manufacturer's recommendations. You may also want a small container for keeping track of fasteners and washers removed during disassembly.

Practical Takeaway: Invest in or borrow the specialized tie rod tools before beginning. Attempting this job without proper tools often results in stripped fasteners, damaged ball joints, or incomplete removal.

Safety Considerations and Vehicle Preparation

Working on steering components requires careful attention to safety procedures. Improper technique or rushing through this job can result in loss of steering control while driving, creating a serious safety hazard. Before beginning any work, park your vehicle on a level, hard surface away from traffic. Engage the parking brake firmly and place wheel chocks behind both rear wheels to prevent accidental movement.

Disconnect the negative battery terminal before starting work. This prevents accidental airbag deployment if you inadvertently contact electrical connections. Allow your vehicle to cool completely if you've been driving recently, as components near the engine and suspension can remain hot enough to cause burns. Wear safety glasses throughout the procedure to protect your eyes from dirt, debris, and fasteners.

Never crawl under a vehicle supported only by a jack. Always use at least two properly rated jack stands positioned on the vehicle's frame at appropriate lift points. Consult your owner's manual for the correct jack point locations. Position the jack stands so they contact the vehicle's solid frame rails, not plastic trim pieces. A hydraulic floor jack should remain under the vehicle as a backup while you work, but the jack stands do the actual support work.

Before lifting the vehicle, loosen the lug nuts on the affected wheel while it's still on the ground. This requires less force than loosening them while the wheel is suspended in the air. Once the vehicle is safely lifted and supported, completely remove the lug nuts and set them aside in a small container where they won't roll away. Remove the wheel by pulling it straight toward you, then set it aside in a safe location.

Practical Takeaway: Take extra time setting up your work area safely. A few additional minutes spent on proper setup prevents injuries and ensures the job proceeds smoothly.

Step-by-Step Removal of the Old Inner Tie Rod

Begin the removal process by locating the outer tie rod end where it connects to the steering knuckle. You'll see a castle nut at the top of this connection point. Use a wrench to hold the tie rod end stud while loosening this castle nut with another wrench. Once loose, remove the nut completely and set it aside. If the castle nut won't come loose easily, spray penetrating oil around the base of the fastener and wait fifteen minutes before trying again.

Now use your tie rod removal tool to separate the outer tie rod from the steering knuckle. Position the tool's jaws around the ball joint stud and tighten the center bolt. This applies even pressure that breaks the taper joint without damaging the component. Some technicians use a pickle fork, which wedges between the steering knuckle and tie rod end to separate them. However, pickle forks can damage the ball joint if too much force is applied, so the proper tie rod removal tool is preferable.

Once the outer tie rod is separated from the steering knuckle, locate where the inner tie rod connects to the steering rack. The inner tie rod is a threaded component that screws directly into the steering rack. Count the number of threads visible between the inner and outer tie rod ends—this measurement helps you install the new inner tie rod at approximately the same length, which minimizes steering wheel alignment issues.

Use your 36mm hex wrench or inner tie rod socket to loosen the inner tie rod from the steering rack. Turn it counterclockwise while supporting the outer tie rod end with your other hand to prevent the entire tie rod assembly from spinning. Once sufficiently loose, you can unscrew the inner tie rod by hand. Some steering systems have a lock nut securing the inner tie rod to the rack; if present, loosen this first before removing the inner tie rod itself.

Practical Takeaway: Write down or photograph the thread count before removal. This reference measurement saves alignment problems during installation.

Installing the New Inner Tie Rod and Making Adjustments

Before installing the new inner tie rod, ensure your replacement part matches the specifications of the original component. Compare part numbers if available, and verify that the new tie rod has the same connection thread pitch as the old one. Some vehicles use right-hand threads while others use left-hand threads, so checking this detail prevents installation errors.

Begin installation by threading the new inner tie rod into the steering rack by hand. Once hand-tight, use your 36mm hex wrench to tighten the tie rod securely while supporting the outer tie rod end with your other hand. Do not overtighten, as excessive force can strip the threads in the steering rack. Refer to your vehicle's service manual for the correct torque specification, typically in the range of 35 to 50 foot-pounds for most
