Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Shock Absorbers/Struts

Tools Required: Socket set, torque wrench, jack stands, spring compressor (if needed)
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the shock absorber/strut assembly.
Sub-steps:
1. Remove the upper and lower mounting bolts of the shock absorber.
2. If equipped with a strut assembly, use a spring compressor to safely remove the coil spring from the strut.
3. Replace the old shock absorber/strut with the new one, ensuring it is properly aligned.
4. Reinstall the coil spring and ensure it is seated correctly.
5. Torque all bolts to the manufacturer's specifications.

3. Replace Control Arms/Bushings (if necessary)

Tools Required: Socket set, pry bar, torque wrench
If control arms are found to be worn or damaged during the inspection:
- Remove the nuts securing the control arm to the frame and ball joint.
- Use a pry bar to detach the control arm from the vehicle.
- Install new bushings if applicable, or replace the entire control arm assembly.
- Reinstall the control arm and torque the bolts to specifications.

4. Replace Sway Bar Links/Bushings (if necessary)

Tools Required: Socket set, torque wrench
Inspect sway bar links and bushings for wear:
- Remove the sway bar link from the sway bar and lower control arm.
- Install new sway bar links and ensure they are tightened to the correct torque.
