Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, jack stands, and possibly replacement parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure the vehicle with jack stands to ensure safety during inspection and repair.

3. Inspect and Replace Components

A. Check Shock Absorbers

Remove the lower mounting bolts of the shock absorbers using a socket wrench.
Inspect for any signs of leakage or damage.
If faulty, replace with OEM or equivalent shock absorbers. Torque the bolts to manufacturer specifications (typically around 30-40 ft-lbs).

B. Inspect Sway Bar Links

Remove the sway bar link bolts.
Check for play or wear in the bushings.
Replace with new sway bar links if necessary, ensuring the bolts are torqued to specification.

C. Inspect Control Arms and Bushings

Remove the control arm bolts.
Check for cracks or excessive wear in the bushings.
Replace any damaged control arm or bushings, ensuring proper torque (usually around 50-60 ft-lbs).

4. Reassemble and Lower Vehicle

Reattach all components securely.
Lower the vehicle from jack stands and remove the jack.
