How to remove steering rack ends?
A clunking noise under your feet or sloppy steering response can ruin your drive. You suspect a worn suspension part, but you don’t know how to get the old one off without breaking something else.

To remove steering rack ends, secure the vehicle on stands, remove the wheel and outer tie rod, cut the boot clamps to expose the joint, and use a specialized inner tie rod tool to unscrew the ball housing from the steering rack.

Replacing this part is a manageable job if you have the right tools. I’ll walk you through unbolting the old unit and installing a new GSW Autoparts replacement correctly.

What are Steering Rack Ends?

Before you start tearing apart your car, you must be 100% sure you are fixing the right part. Confusing terminology often leads to buying the wrong components.

Steering rack ends, also called inner tie rods or axial joints, are the flexible links connecting the steering rack gearbox to the outer tie rod ends. They transmit steering force while allowing for suspension travel.

Working on the GSW Autoparts floor, I’ve handled thousands of these. We often label them "Axial Joints" because the force is applied in a straight line along the axis of the rod.

The rack end consists of two main parts: the ball housing and the rod shaft. The ball housing screws directly into the steering rack gear. This is the part hidden inside the rubber bellows boot. The long shaft extends out and screws into the outer tie rod end.

I often see customers mix up "inner" and "outer" tie rods.

• Inner (Rack End): Connects to the steering box. Has a ball joint and a long threaded male end.
• Outer (Tie Rod End): Connects to the wheel knuckle. Has a short 90-degree ball stud.

If you grab the linkage behind the wheel and feel play near the engine, it’s the rack end. If the play is near the wheel, it’s the outer tie rod.

How to Replace a Steering Rack End?

This is the critical part of the job. Do it wrong, and you’ll ruin your alignment or damage the steering rack seals.

You need an inner tie rod tool, a floor jack, and basic wrenches. Measure the exposed thread length first, disconnect the outer tie rod, remove the dust boot, uncrimp the lock washer if present, and unscrew the rack end counter-clockwise.

I’ve seen many DIYers try to use pipe wrenches or vise grips for this. Please don’t. The space is tight. I remember a mechanic calling us because he stripped the hex head on the rack end using the wrong tool. He turned a one-hour job into a six-hour nightmare.

Step-by-Step Removal Guide:

1. Prep: Lift the front end and support it on jack stands. Remove the front wheel.
2. Measure: Before you loosen anything, take a tape measure. Measure the distance from the end of the rack end threads to the center of the outer tie rod. Write this number down. You will need it to set the length of the new part so you can drive safely to the alignment shop.
3. Separate Outer Tie Rod: Loosen the jam nut (the nut locking the inner and outer rods together). Then, remove the nut connecting the outer tie rod to the knuckle. You might need a hammer to strike the knuckle side to pop the joint loose.
4. Remove Boot: This can be annoying. There are clamps on both ends of the rubber boot. Cut the outer clamp. The inner clamp is often a reusable spring clip or a zip tie. Remove them and slide the boot off. Inspect the boot for cracks. If it’s torn, replace it now.
5. Unlock the Joint: Look where the rack end screws into the steering rack. Many vehicles use a "lock washer" with bent tabs holding the nut in place. You must hammer a screwdriver to flatten these tabs. If you don’t, it won’t unscrew.
6. Unscrew: Slide your inner tie rod tool over the shaft. It will grip the hex nut at the base. Attach a ratchet and turn counter-clockwise to remove it.

Installation Tips:

• Clean Threads: Wipe the threads on the steering rack clean.
• Thread Locker: Apply a small amount of blue thread locker (Loctite) to the new threads if the manual suggests it.
• Torque: Tighten the new rack end firmly.
• Grease: If the new part has a zirk fitting (rare on inners, but possible), add grease.
• Re-clamp: Make sure the boot is sealed tight. Water entering here will destroy your steering rack.

Do You Have to Remove the Steering Rack?

Sometimes the damage goes beyond just the rod. You ask if you need to pull the whole steering gearbox out just to change the rod.

No, you do not need to remove the steering rack to change the rack ends. However, if the rack itself is leaking fluid or has internal play, you must drain the fluid, disconnect the steering column, unbolt the subframe, and lower the assembly.

I want to be very clear: Removing the entire steering rack is a major repair. I only recommend this if the main seals are leaking or the internal gears are worn. For just a rack end (inner tie rod) replacement, the rack stays in the car.

However, I have seen cases where neglecting a bad rack end for too long caused impact damage to the rack bar itself. In that case, you have to pull the whole unit.

The process varies by car, but generally involves:

1. Lock Wheel: Secure the steering wheel center with a seatbelt or lock. If it spins freely while disconnected, you will break the clockspring (airbag sensor).
2. Lines: Disconnect hydraulic pressure and return lines. Have a bucket ready; fluid will go everywhere.
3. Column: Disconnect the steering shaft coupler near the driver’s pedals or in the engine bay.
4. Mounts: Remove the large bolts holding the rack to the subframe.
5. Wiggle it Out: This is the hardest part. Usually, you have to twist and turn it to clear the engine and exhaust.

What Happens When a Steering Rack End Goes Bad?

You might think a little play in the wheel is normal for an older truck. It’s not. Ignoring the symptoms leads to expensive collateral damage.

When a rack end fails, you will experience excessive steering play, uneven tire wear, clunking noises over bumps, and eventually, the risk of wheel separation if the ball pops out of the socket.

I remember a fleet owner who delayed maintenance on his delivery vans to save money. He ignored driver complaints about "loose steering¹." One of the vans blew a tire on the highway because the bad rack end caused severe alignment issues. The tire had worn down to the wire on the inside edge, even though the outside looked new. The cost of that one blowout was more than replacing rack ends² on three vans.

Key Symptoms of Failure:

• "Dead Spot": You turn the wheel an inch or two, but the car goes straight. That’s the ball joint moving loosely inside the housing. The input is just pushing the ball around the gap, not pushing the rod.
• Feathered Tires: Run your hand across the tire tread. If it feels smooth one way and rough (like a saw blade) the other, that’s "feathering." It means the tire is being dragged sideways because the toe angle keeps changing.
• Shimmy: The worn joint wiggles at highway speeds, causing the steering wheel to shake in your hands.
• Shake Test: Jack up the car. Grab the tire at 3 and 9 o’clock. Shake it left and right. If the wheel moves but the steering wheel doesn’t, check the inner tie rod. If the rod is moving into the boot but the rack gear isn’t moving, the joint is bad.

Safety is the priority. The rack end is the only thing pushing your wheels to turn. If it breaks, you have no control.

Conclusion

Removing a steering rack end requires specific tools and attention to detail, but it saves your tires and restores tight handling. Always measure thread length before removal and get an alignment immediately after installation.
