How to Change Wheel Bearings

Changing wheel bearings is a relatively complex task that requires specialized tools and skills. It is recommended that you have this work done by a qualified mechanic.

However, if you are comfortable working on your own vehicle, the following steps will guide you through the process:

Step 1: Gather your tools

You will need the following tools:

• Jack and jack stands
• Lug wrench
• Socket wrench
• Ball joint separator
• Slide hammer
• New wheel bearing
• Grease

Step 2: Safety first

Park your vehicle on a level surface and engage the parking brake. Chock the wheels behind the one that you will be working on.

Step 3: Remove the wheel

Use the lug wrench to loosen the lug nuts on the wheel. Do not remove them completely.

Jack up the vehicle and place a jack stand under the frame.

Remove the lug nuts and take off the wheel.

Step 4: Remove the brake caliper

Unbolt the brake caliper from the steering knuckle and hang it out of the way. Do not let it hang by the brake hose.

Step 5: Remove the rotor

Remove the rotor from the wheel hub.

Step 6: Remove the axle nut

Use the socket wrench to remove the axle nut.

Step 7: Separate the ball joint

Use the ball joint separator to separate the ball joint from the steering knuckle.

Step 8: Remove the steering knuckle

Unbolt the steering knuckle from the control arm and remove it from the vehicle.

Step 9: Remove the old wheel bearing

Use the slide hammer to remove the old wheel bearing from the steering knuckle.

Step 10: Install the new wheel bearing

Pack the new wheel bearing with grease and install it into the steering knuckle.

Step 11: Reassemble the steering knuckle

Reattach the steering knuckle to the control arm and bolt it into place.

Step 12: Install the axle nut

Tighten the axle nut to the specified torque.

Step 13: Install the rotor

Install the rotor onto the wheel hub.

Step 14: Install the brake caliper

Bolt the brake caliper back onto the steering knuckle.

Step 15: Install the wheel

Put the wheel back on and tighten the lug nuts.

Step 16: Lower the vehicle

Lower the vehicle and remove the jack stand.

Step 17: Tighten the lug nuts

Tighten the lug nuts to the specified torque.

Step 18: Road test

Take your vehicle for a road test to ensure that the wheel bearing is working properly.

Tips and Tricks

• Use a torque wrench to tighten all bolts and nuts to the specified torque. This will help to prevent overtightening and damage.
• Use grease on all moving parts to reduce friction and wear.
• If you are not comfortable working on your own vehicle, have the work done by a qualified mechanic.

Common Mistakes to Avoid

• Overtightening bolts and nuts. This can damage the bolts, nuts, and threads.
• Not using grease. This can lead to increased friction and wear.
• Installing the wrong wheel bearing. This can lead to premature failure.
