Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection

Remove the wheel covers or hubcaps if necessary.
Inspect tire tread for uneven wear, and check tire pressure with a gauge.
Replace any damaged tires or inflate them to the manufacturer’s recommended pressure.

3. Suspension Component Replacement

Inspect and Replace Shocks/Struts:
- Jack up the vehicle and secure it on jack stands.
- Remove the wheels to gain access to the suspension.
- Detach the shocks/struts by removing the bolts at the top and bottom mounts.
- Install new shocks/struts, ensuring proper torque specifications for bolts (typically around 25-35 ft-lbs).

4. Steering Component Repair

Inspect and Replace Tie Rod Ends and Ball Joints:
- With the wheels still removed, check the tie rod ends for any play by moving them side to side.
- If play is present, remove the cotter pin and nut from the tie rod end and disconnect it from the steering knuckle.
- Replace with a new tie rod end, tightening the nut to the specified torque (usually 40-60 ft-lbs).
- Repeat for any ball joints showing signs of wear.

5. Wheel Alignment

After replacing worn components, perform a wheel alignment to ensure proper handling and tire wear.
Adjust the alignment settings according to manufacturer specifications.
