Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Shock Absorbers

Tools Required: Socket set, wrench set, torque wrench, jack, jack stands, and safety goggles.
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the rear or front wheel (depending on which shock absorbers are being replaced).
3. Locate the shock absorber and remove the bolts securing it to the mounting points.
4. Remove the old shock absorber and install the new one, ensuring proper orientation.
5. Torque the mounting bolts to the manufacturer-recommended specifications (typically around 50-80 ft-lbs).
6. Reinstall the wheel and lower the vehicle.

3. Replace Worn Bushings

Tools Required: Socket set, pry bar, and bushing removal tool.
Sub-steps:
1. Remove the affected control arm or sway bar as necessary.
2. Use a bushing removal tool to extract old bushings from the control arm.
3. Clean the mounting surfaces and install new bushings, ensuring they are properly aligned.
4. Reinstall the control arm or sway bar and torque bolts to specifications.
