Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather tools and parts required for the repair.
Safety warning: Ensure the vehicle is securely supported with jack stands before working underneath.

2. Inspect and Replace Suspension Components

Inspect Struts and Shocks:
- Remove the wheel to gain access to the suspension.
- Check for any visible leaks or damage on struts and shocks.
- If damaged, proceed to replace them:
  1. Disconnect the upper mounting bolts using a socket set.
  2. Remove the lower bolts from the control arm and carefully extract the strut/shock assembly.
  3. Install the new strut/shock in reverse order, tightening bolts to manufacturer specifications (Refer to service manual for torque values).
Check Sway Bar Links:
- Inspect sway bar links for wear or looseness.
- If necessary, replace the sway bar links by removing the retaining bolts with a wrench.
- Install new links, ensuring they are properly torqued.
Replace Bushings:
- If bushings are worn, remove the components they are attached to (e.g., control arms).
- Use a bushing removal tool to extract the old bushings.
- Install new bushings, ensuring they are seated properly.
