Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools and parts.

2. Tire Inspection and Replacement

Check Tire Condition
- Inspect all tires for uneven wear, bulges, or damage.
- If damage is found, replace the affected tire(s) with the correct size and type.
Adjust Tire Pressure
- Use a tire pressure gauge to measure the pressure.
- Inflate or deflate tires to match the manufacturer's recommended PSI, usually found on the driver’s door jamb sticker.

3. Suspension Component Assessment

Inspect Suspension
- Raise the vehicle using a jack and secure it on jack stands.
- Visually inspect shock absorbers, struts, and control arm bushings for signs of wear or leaks.
- Replace any worn or damaged components as necessary.
Replace Suspension Components
- If struts or shocks are worn, remove them using a socket set.
- Replace with OEM or high-quality aftermarket parts, following the manufacturer’s torque specifications (usually around 40-70 ft-lbs for strut bolts).

4. Wheel Bearing Inspection and Replacement

Check Wheel Bearings
- Spin each wheel by hand to check for noise or excessive play.
- If issues are found, remove the wheel and hub assembly for further inspection.
Replace Wheel Bearings
- Remove the hub assembly and press out the old bearings using a bearing puller.
- Install new bearings and reassemble the hub using a torque wrench to manufacturer specifications.
