How to Replace Back Wheel Bearings Step-by-Step

Replacing back wheel bearings is a complex procedure that requires specialized tools and knowledge. If you are not experienced in automotive repair, it is recommended to have the work performed by a qualified mechanic.

Step 1: Gather Materials

Before you begin, gather the following materials:

• Replacement back wheel bearings
• Bearing grease
• Lug wrench
• Torque wrench
• Socket set
• Jack and jack stands

Step 2: Safety First

Park the vehicle on a level surface and engage the parking brake. Place wheel chocks behind the front wheels.

Step 3: Remove the Wheel

Use a lug wrench to loosen the lug nuts on the wheel with the bad back wheel bearing. Do not remove the lug nuts completely.

Step 4: Jack Up the Vehicle

Place a jack under the frame rail near the bad back wheel bearing. Pump the jack to raise the vehicle until the tire is off the ground.

Step 5: Remove the Bad Bearing

Use a socket set to remove the hub assembly. The bearing should pull out easily.

Step 6: Install the New Bearing

Pack the new bearing with grease and carefully slide it into place. Tighten the hub assembly according to the manufacturer's specifications.

Step 7: Reinstall the Wheel

Lift the wheel onto the hub and tighten the lug nuts by hand. Tighten the lug nuts to the manufacturer's specifications using a torque wrench.

Step 8: Lower the Vehicle

Slowly lower the vehicle to the ground. Remove the jack and wheel chocks.
