Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and allow any hot components to cool.

2. Tire Inspection and Replacement (if necessary)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressure with a gauge and inflate to manufacturer specifications if low.
Inspect tires for uneven wear or damage.
If tires are worn, remove the wheel using a lug wrench, replace with new tires, and re-torque to manufacturer specifications (usually around 80-100 ft-lbs).

3. Suspension Component Inspection and Replacement

Tools Required: Socket set, torque wrench, pry bar, suspension tool set.
Lift the vehicle using a jack and secure it with jack stands.
Inspect shocks and struts for leaks or physical damage. Replace if necessary.
- Sub-steps for Replacement:
  1. Remove the wheel to access the suspension.
  2. Unbolt the top mount of the shock/strut assembly.
  3. Remove the lower mounting bolts and detach the assembly.
  4. Install the new shock/strut and reassemble in reverse order, ensuring to torque bolts to specifications.
Check control arms and bushings for wear; replace if necessary.

4. Sway Bar Link Inspection and Replacement

Tools Required: Wrench set, socket set.
Inspect sway bar links for any play or damage.
If damaged, remove the old sway bar link and replace with a new one, ensuring proper torque when reattaching.
