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 to ensure safety during repairs.

2. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, jack stands, and possibly a spring compressor.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel on the affected side to gain access to the suspension components.
3. Inspect the struts and shocks for leaks or damage. If damaged, remove the strut/shock assembly:
  - Remove the top mounting bolts using a socket.
  - Remove the lower bolts securing the strut to the control arm.
4. Replace with new struts or shocks if necessary, ensuring all mounting points are secure.
5. Reinstall the wheel and lower the vehicle.
6. Repeat for the opposite side if needed.

3. Replace Worn Sway Bar Links and Bushings

Tools Required: Wrench set, socket set.
Sub-steps:
1. Locate the sway bar links and bushings on the front and rear suspension.
2. Use a wrench to remove the nuts securing the sway bar links.
3. Inspect the bushings for wear; if cracked or degraded, replace them.
4. Install new sway bar links and bushings, tightening to manufacturer specifications (typically around 15-20 lb-ft).

4. Final Assembly

Recheck all bolts for proper torque.
Reinstall the wheel and lower the vehicle.
Connect the battery.
