Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Tires

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Use a tire pressure gauge to check all tire pressures and inflate as needed.
3. Inspect the tread depth with a tread depth gauge and replace any tires showing excessive wear or damage.
4. Rotate tires if uneven wear is detected.
Tools Required: Tire pressure gauge, tread depth gauge, jack, jack stands, lug wrench.

3. Inspect and Repair Suspension Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect struts, shocks, control arms, and bushings for signs of wear or damage.
3. Replace any worn or damaged components with OEM or quality aftermarket parts.
4. Ensure all bolts are tightened to manufacturer specifications (typically found in the service manual).
Tools Required: Socket set, torque wrench, pry bar.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel and brake assembly.
2. Check for play in the wheel bearings by shaking the hub.
3. If play is detected, replace the wheel bearing assembly.
4. Reassemble the brake and wheel assembly, ensuring all fasteners are torqued to spec.
Tools Required: Bearing puller, socket set, torque wrench.
