Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, pry bar, jack stands, and safety glasses.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Shock Absorbers

Inspect: Remove the rear wheels to access the shock absorbers. Examine for leaks or physical damage.
Remove: Use the socket set to remove the bolts securing the shocks. Carefully pull the shock out from the mount.
Replace: Install the new shock absorbers by reversing the removal steps. Torque bolts to manufacturer specifications (typically around 40-50 ft-lbs).

3. Check and Replace Sway Bar Links

Inspect: Check sway bar links for play. Use a pry bar to test for any movement.
Remove: Use a socket set to remove the bolts securing the sway bar links to the sway bar and lower control arm.
Replace: Install new sway bar links, ensuring they are properly aligned. Torque to manufacturer specifications (usually around 20-30 ft-lbs).

4. Inspect and Replace Bushings

Inspect: Check the condition of bushings on control arms and sway bars for degradation.
Remove: If damaged, use a pry bar to remove the old bushings from their mounts.
Replace: Install new bushings, applying lubricant if specified. Ensure proper orientation and fit before reassembling.
