Next, use a socket wrench and remove the caliper bolts and slide the brake assembly off the rotor. Use wire or a bungee cord to suspend the brake assembly, so it doesn’t hang from the brake line.

2. Remove the bearing hub and dust cover

Use a pair of pliers or a screwdriver and remove the cotter pin, castle nut, and washer that secure the bearing hub to the axle spindle. Pull the hub assembly off the spindle, and you’ll see the bearing races and the grease seal inside it. Use a pry bar or a hammer and chisel to remove the dust cover or bearing retainer clip that holds the races in place.

3. Clean the hub assembly and axle spindle

Before installing the new bearings, you need to the hub assembly and axle spindle thoroughly. Use brake parts cleaner, a shop towel, and a soft brush to remove dirt, grease, and any debris from the surfaces. Inspect the spindle for any nicks, scratches, or wear that could damage the new bearings. If necessary, use sandpaper to smooth out any imperfections.

4. Install the new bearings and grease seal

Apply a thin layer of high-temperature wheel bearing grease to the inside of the bearing races and the axle spindle. Then, insert the new bearings into the hub assembly, pressing them in with a bearing installation tool or a socket that fits the outer race. After that, install a new grease seal over the bearings with the lip facing inward. Tap it gently with a hammer or a seal driver until it seats properly.

5. Reassemble the hub and brake assembly

Slide the hub assembly back onto the spindle, making sure that the bearing races align with the spindle’s surfaces. Then, install the washer, the castle nut, and the cotter pin, tightening the nut to the manufacturer’s torque specification. Bend the cotter pin ends around the nut’s grooves to secure it in place. Finally, reattach the brake assembly and the wheel following the same order you removed them.

6. Test drive the car

After changing the wheel bearings, you should test drive the car to ensure everything works fine. Listen for any unusual noise or vibration, check for proper braking performance, and observe the steering and handling feel. If you notice any issues, stop immediately and inspect the bearings and the assembly again.

In conclusion, changing the wheel bearings of a car is not an extremely complex task, but it requires some mechanical skills and attention to detail. If you feel uncertain or uncomfortable doing it yourself, it’s best to seek professional assistance. Remember, wheel bearings impact your car’s safety and performance, so don’t skimp on quality replacements and installation.
