🔧 Suspension Bushings - Front Lower Control Arm Bushing Replacement

This guide covers the most common suspension bushing service on your RAV4: the front lower control arm bushings. These bushings reduce noise, vibration, and looseness in the front suspension, and worn ones can cause clunks, steering wander, and uneven tire wear.

Difficulty Level: Advanced | Estimated Time: 4-6 hours

⚠️ Safety & Precautions

• Work on a level surface and support the vehicle with jack stands before removing any suspension parts.
• Use wheel chocks on the rear wheels.
• Do not work under a vehicle supported only by a jack.
• Front suspension fasteners may be tight; use correct tools to avoid rounding bolts.
• After suspension work, a wheel alignment is required.
• Hybrid system shutdown is not required for this mechanical repair, but keep the vehicle OFF and the key fob away from the car.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the front wheel

• Use a 21mm socket to loosen the lug nuts, then remove the wheel after lifting the vehicle.
• Set the wheel aside safely.

Step 2: Inspect and mark alignment points

• Use a paint marker to mark the position of the control arm cam bolts and brackets.
• This helps keep the alignment close enough to drive to the shop.

Step 3: Remove the lower control arm

• Use a 17mm socket and 19mm socket to remove the lower control arm bolts and nuts.
• Use a breaker bar if the bolts are tight.
• If the ball joint is attached to the knuckle, use a 19mm socket to remove the ball joint nut.
• Use a ball joint separator (specialty) to free the ball joint from the steering knuckle if needed.
• Torque on reassembly: 103 Nm (76 ft-lbs) for lower arm-to-body mounting bolts unless the service fastener spec on your control arm differs.

Step 4: Remove the old bushings

• Use a hydraulic press (specialty) or bushing press kit (specialty) to press the old bushings out of the control arm.
• Clean the bore with a bolt brush and inspect for cracks or elongation.
• Press straight to avoid damaging the arm.

Step 5: Install the new bushings

• Use the hydraulic press (specialty) or bushing press kit (specialty) to install the new bushings in the same orientation as the originals.
• Lightly lubricate only if the bushing manufacturer allows it.
• Make sure the bushing is fully seated and aligned.

Step 6: Reinstall the control arm

• Position the control arm back in place and hand-start all bolts.
• Use a 17mm socket and 19mm socket to reinstall the mounting hardware.
• Do not fully tighten rubber-bushed pivot bolts with the suspension hanging.
• Raise the suspension to normal ride height before final tightening.
• Torque to 103 Nm (76 ft-lbs) for the lower arm mounting bolts at ride height.

Step 7: Reinstall wheel and lower vehicle

• Reinstall the wheel using a 21mm socket.
• Lower the vehicle and torque the lug nuts in a star pattern.
• Torque to 103 Nm (76 ft-lbs) for the lug nuts.

Step 8: Road test and inspect

• Drive slowly at first and listen for clunks or rubbing.
• Check the repaired side for looseness or shifting.
• Schedule a four-wheel alignment as soon as possible.

✅ After Repair
