Solution

1. Preparation

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

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Check tire pressure and inflate to recommended PSI.
2. Inspect tread depth and look for any bulges or cracks.
3. If tires are worn or damaged, remove the wheel using a lug wrench.
4. Install new tires, ensuring they are correctly balanced.
5. Torque lug nuts to the manufacturer-specified value (usually around 80-100 ft-lbs).

3. Inspect and Replace Shock Absorbers

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel for better access to the suspension components.
3. Unbolt the upper and lower mounts of the shock absorber using a socket set.
4. Remove the old shock absorber and install the new one, ensuring proper alignment.
5. Reattach the upper and lower mounts and torque to manufacturer specifications.

4. Check and Replace Bushings and Mounts

Sub-steps:
1. Inspect all suspension bushings and mounts for signs of wear or cracking.
2. If damaged, use a bushing removal tool to take out old bushings.
3. Apply lubricant to the new bushings and install them in their respective locations.
4. Ensure all mounts are securely fastened and torqued to specifications.

5. Alignment Adjustment

Sub-steps:
1. After replacing components, take the vehicle to a professional alignment shop.
2. Ensure that the alignment is set according to manufacturer specifications.
3. Monitor for any steering issues post-alignment.
