Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Suspension Components

Remove Rear Wheels
- Use a lug wrench to remove the lug nuts and take off the rear wheels.
Examine and Replace Shocks/Struts
- Locate the upper and lower mounting bolts of the rear shocks.
- Use a socket set to remove the bolts and detach the shocks from the vehicle.
- Install new shocks by aligning them at the mounting points and securing them with bolts. Torque bolts to the manufacturer's specifications (usually around 30-40 ft-lbs).
Check and Replace Bushings
- Inspect control arm bushings for wear or damage.
- Use a bushing removal tool to remove old bushings and install new ones.
- Ensure they are seated properly and secured.
Inspect Sway Bar Links
- Check the sway bar links for play or damage.
- Use a wrench to remove and replace worn sway bar links.

3. Wheel Alignment

Set Up Alignment Equipment
- Position the vehicle on an alignment rack.
- Follow the manufacturer's specifications for alignment settings.
Adjust Alignment Angles
- Adjust the camber, caster, and toe settings as necessary.
- Tighten all bolts to the specified torque settings.
