Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Tires (if necessary)

Remove the tires:
1. Loosen lug nuts using a lug wrench.
2. Jack up the vehicle and remove the lug nuts and tires.
Inspect the tires:
1. Check for uneven wear patterns, bulges, or cuts.
2. Replace any tires that are damaged or excessively worn.
Reinstall tires:
1. Place the tires back on the hubs.
2. Hand-tighten lug nuts, then lower the vehicle and torque to the manufacturer's specifications (typically 76 ft-lbs for Corolla).

3. Check and Replace Wheel Bearings (if necessary)

Remove the wheel assembly:
1. Follow the steps in "Inspect and Replace Tires."
2. Remove brake caliper and rotor.
Inspect the wheel bearings:
1. Spin the hub and listen for noise or roughness.
2. If faulty, remove the hub assembly.
Replace bearings:
1. Use a bearing puller to remove old bearings.
2. Press in new bearings using a bearing press, ensuring proper alignment.
Reassemble:
1. Reinstall the hub, brake rotor, and caliper.
2. Reattach the wheel as previously described.

4. Inspect and Replace CV Joints/Axles (if necessary)

Check CV joints:
1. Inspect for torn boots or leaks.
2. If damaged, detach the axle from the hub and transmission.
Replace CV joints/axles:
1. Remove the old axle by pulling it out of the transmission.
2. Install the new axle and ensure it clicks into place.
Reassemble:
1. Reattach the wheel assembly following previous instructions.

5. Fluid Inspection and Replacement (if necessary)

Check transmission fluid:
1. Locate the transmission dipstick or fill plug.
2. Pull the dipstick and check the fluid level and condition (should be bright red and clear).
Replace fluid:
1. If low or burnt, drain the old fluid and replace it with the manufacturer-recommended fluid.
2. Recheck the level after adding fluid.
