Rear Control Arm Bushing Replacement: Fixing a Wheel Sitting Too Far Back in the Wheel Well

Noticing your wheel sitting too far back in the wheel well is more than a cosmetic issue. It means something in your rear suspension geometry has changed, and the most common culprit is a worn or broken rear control arm bushing. If you ignore it, you'll deal with uneven tire wear, poor handling, and potential damage to other suspension components. Knowing how to replace rear control arm bushing when wheel sits too far back in wheel well can save you hundreds of dollars in shop labor and get your alignment back where it belongs.

What causes the wheel to sit too far back in the wheel well?

Your rear control arm (sometimes called a trailing arm or lower control arm, depending on your vehicle) connects the wheel hub assembly to the frame or subframe. Rubber or polyurethane bushings sit at each mounting point and absorb road shock while keeping the wheel in proper alignment. When those bushings crack, collapse, or tear, the control arm can shift under load. This pulls the wheel backward in the wheel well.

Common causes include:

Worn-out rubber bushings from age and mileage
Impact damage from hitting a pothole or curb
Failed polyurethane bushings that weren't properly lubricated
Corroded control arm mounting points allowing play

Drivers often notice the symptom first the wheel looks off-center in the fender opening, usually pushed toward the rear of the car. You might also feel the vehicle pulling to one side, hear clunking over bumps, or see the rear tires wearing unevenly on the inside or outside edges.

How do I confirm the bushing is the problem?

Before you start wrenching, confirm that the rear control arm bushing is actually the cause. Here's how to diagnose it:

Visual inspection: Get under the car (safely on jack stands) and look at the control arm bushings. Cracked, split, or missing rubber chunks are obvious signs. Sometimes the bushing sleeve will be visibly shifted out of its housing.
Pry bar test: Place a pry bar between the control arm and the mounting bracket. If there's excessive movement (more than a tiny amount), the bushing is worn. Compare both sides the bad side will have noticeably more play.
Check alignment specs: If your rear toe or thrust angle is way off and can't be adjusted back to spec, a collapsed bushing is often the reason.

If the wheel shifted after hitting a pothole or curb, the damage may be more sudden and obvious. In that case, check out what to do when the wheel moves backward in the wheel well after hitting a pothole for more specific repair steps.

What tools and parts do I need to replace the rear control arm bushing?

Gather everything before you start. Stopping mid-job to run to the parts store is frustrating and can lead to mistakes.

Parts

Replacement bushings (OEM rubber or upgraded polyurethane)
New control arm bolts and nuts (recommended, since old ones may be stretched or corroded)
Anti-seize compound or chassis grease (especially for polyurethane bushings)

Tools

Floor jack and jack stands (minimum two, four preferred)
Wheel chocks
Socket set and breaker bar
Torque wrench
Bushing press or C-clamp with sockets (for pressing bushings in and out)
Penetrating oil (PB Blaster or similar)
Wire brush
Safety glasses and gloves

How to replace rear control arm bushing when wheel sits too far back in wheel well step by step

Step 1: Secure the vehicle

Park on a flat, level surface. Engage the parking brake and chock the front wheels. Raise the rear of the vehicle with a floor jack and place jack stands under the frame or designated lift points. Never work under a car supported only by a jack.

Step 2: Remove the wheel

Loosen the lug nuts while the tire is on the ground, then raise the car and remove the wheel. Set it aside somewhere it won't roll.

Step 3: Locate the control arm and bushings

Find the rear control arm it runs from the subframe or frame mount to the wheel knuckle or axle housing. You'll see the bushings at each end where the arm bolts to the frame and to the knuckle. The frame-side bushing is usually the one that fails first, but inspect both.

Step 4: Soak the bolts with penetrating oil

Spray all mounting bolts generously and let them soak for at least 15–20 minutes. Rust and corrosion make these bolts extremely difficult to remove, especially in northern climates where road salt is common.

Step 5: Support the suspension and remove the control arm

Place a jack under the knuckle or axle to support it. Remove the control arm mounting bolts. Some vehicles have cam bolts that set rear alignment if yours does, mark their position before removal. The control arm should now come free.

Step 6: Press out the old bushings

Using a bushing press kit or a large C-clamp with appropriately sized sockets, press the old bushings out of the control arm. If they're badly deteriorated, they may crumble out. Clean the bushing bore with a wire brush and check for cracks or deformation in the arm itself.

Step 7: Install the new bushings

Press the new bushings into the control arm. Make sure they're fully seated and aligned correctly most bushings have a specific orientation. If you're using polyurethane bushings, apply the included grease or a quality chassis lube to prevent squeaking.

Step 8: Reinstall the control arm

Bolt the control arm back into place. Hand-tighten all bolts first to make sure everything lines up. If your vehicle uses cam bolts for rear alignment adjustment, set them back to your marked position as a starting point.

Step 9: Torque to spec

This step matters more than most people realize. Torque the control arm bolts to the manufacturer's specification. On many vehicles, the final torque should be applied with the suspension loaded (at ride height), not hanging in the air. Failing to do this preloads the bushing and causes premature failure.

Step 10: Reassemble and align

Reinstall the wheel, lower the vehicle, and torque the lug nuts. Get a four-wheel alignment as soon as possible. This is not optional. Even small changes in bushing position affect toe, camber, and thrust angle.

What are the most common mistakes when replacing control arm bushings?

This job seems straightforward, but several mistakes can turn it into a headache or leave you with the same problem you started with.

Not getting an alignment afterward: Replacing the bushing changes the arm's position. Without an alignment, your wheel could still sit off-center, and your tires will wear out fast.
Torquing bolts with the suspension hanging free: This twists the bushing at ride height, causing it to tear or bind. Always load the suspension to ride height before final torque.
Ignoring the other side: If one bushing failed, the other side is likely close behind. Replacing both sides prevents you from doing this job again in a few months.
Skipping the grease on polyurethane bushings: Poly bushings squeak loudly without proper lubrication. Use the supplied grease generously.
Reusing stretched or corroded bolts: Old bolts may not hold torque properly. New hardware is cheap insurance.
Overlooking a bent control arm: If the wheel shifted because of a hard impact, the control arm itself may be bent. A new bushing in a bent arm won't fix your wheel position. Inspect the arm for visible bends or compare measurements side to side.

Understanding what makes a bushing shift the wheel backward in the first place can help you avoid replacing parts that aren't actually the root cause.

Should I replace the whole control arm or just the bushings?

This depends on the condition of the arm and the cost difference. On many vehicles, a complete control arm with new bushings pre-installed costs only $20–$50 more than bushings alone. The advantage is guaranteed fitment, fresh ball joints (if the arm includes one), and no need for a press.

If you go with just bushings, you'll save money but you'll need access to a press or a loaner tool from your local auto parts store. Either approach works the key is making sure the arm is straight and the new bushings are properly seated.

How long does this repair take?

For someone with basic mechanical experience and the right tools, expect about 1.5 to 3 hours per side. Rusty bolts and stuck bushings are the biggest time killers. If the bolts are badly corroded, budget extra time for soaking them in penetrating oil, potentially using heat, or drilling out a broken bolt.

A shop will typically charge 2–4 hours of labor for this job, plus the alignment, which adds another $80–$150 depending on your area.

Can I drive with a bad rear control arm bushing?

You can, but you shouldn't drive far or fast. A severely worn bushing lets the wheel move unpredictably under braking and cornering. That reduces your control of the vehicle and accelerates tire wear. If the bushing has completely separated, the control arm could shift enough to contact other components or affect your ability to steer.

Drive slowly and carefully to a repair shop or your home garage. Avoid highways and sharp turns until the repair is done.

Practical checklist before you start this job

Confirm the bushing is the actual cause (visual check, pry bar test, alignment data)
Inspect the control arm for bends or cracks
Order both sides if the other bushing shows wear
Gather all tools and parts before lifting the vehicle
Soak all bolts with penetrating oil at least 20 minutes before removal
Mark cam bolt positions if your vehicle uses them for alignment
Press out old bushings, clean the bore, and verify the new bushings are seated correctly
Load the suspension to ride height before torquing control arm bolts to spec
Reinstall the wheel, lower the vehicle, and torque lug nuts
Schedule a four-wheel alignment immediately after the repair
Test drive at low speed and check for noises, vibrations, or pulling
Re-torque control arm bolts after 50–100 miles as a precaution
