Step-by-Step Guide:
1. Vehicle Preparation:
Engage the parking brake and then loosen the lug nuts on the rear wheel you're working on (don't remove them yet).
Use a jack and jack stands to safely raise the vehicle off the ground.
Once raised, remove the lug nuts and the wheel.
2. Remove Brake Components:
Remove the brake caliper by removing its bolts.
Carefully hang the caliper using a piece of wire to prevent it from dangling.
Remove the brake rotor.
3. Access the Wheel Bearing Assembly:
Pry off the dust cap covering the wheel bearing assembly using a pry bar and flat-head screwdriver.
Remove the hub nut using the hub nut socket.
4. Separate the Bearing Assembly:
Pry off the bearing hub using a pry bar.
Continue prying until the bearing assembly is completely removed.
5. Remove Old Bearing:
Using the hammer, gently tap on the old bearing to drive it out of the wheel hub.
6. Clean and Inspect:
Thoroughly clean the wheel hub and bearing assembly to remove old bearing debris and grease.
Inspect for any damage or excessive wear. Replace any damaged components if necessary.
7. Insert New Bearing:
Press the new bearing into place using a press or by gently tapping it in with a hammer.
8. Apply Grease:
Apply bearing grease to the new bearing and the hub before reassembling.
9. Re-attach Bearing Assembly:
Re-attach the bearing assembly to the wheel hub.
10. Hub Nut:
Replace the hub nut and tighten it as much as possible.
11. Re-attach Brake Components:
Re-install the brake rotor, brake caliper, and lug nuts.
12. Lower Vehicle:
Slowly lower the vehicle using the jack and jack stands.
13. Tighten Lug Nuts:
Fully tighten the lug nuts in a star pattern.
14. Test Drive:
Take the car for a short test drive, listening for any unusual noises.
Note:
Proper torque specifications should be followed while tightening lug nuts and hub nuts. Refer to the Mitsubishi Galant service manual for specific values.
If you're not comfortable with any of these steps or have limited automotive knowledge, it's best to leave this task to a professional mechanic.
