Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use a jack to lift the vehicle and secure it with jack stands.

2. Inspect and Replace Struts/Shocks

Sub-steps:
1. Remove the wheel to access the suspension components.
2. Disconnect the strut from the strut mount at the top by removing any bolts using a socket set.
3. Remove the lower strut bolts connecting it to the control arm.
4. Carefully remove the strut/shock assembly from the vehicle.
5. Compare the old strut with the new one to ensure correct replacement.
6. Install the new strut in reverse order, tightening bolts to manufacturer specifications (typically around 50-60 ft-lbs for lower bolts).
7. Reattach the wheel and lower the vehicle.

3. Replace Worn Bushings or Sway Bar Links

Sub-steps:
1. Locate the bushings or sway bar links needing replacement.
2. Remove any retaining bolts or nuts using a socket set.
3. Replace with new bushings or sway bar links, ensuring proper orientation.
4. Secure with bolts and tighten to the specified torque (usually around 30-40 ft-lbs).
5. Recheck all connections and components for tightness.
