Solution

1. Preparation

Gather tools and necessary replacement parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Shocks/Struts

Tools Required: Socket set, torque wrench, spring compressor, ratchet, and extension.
Remove the wheel on the affected side.
Use a spring compressor to relieve tension on the strut assembly.
Remove the strut assembly by unbolting it from the wheel hub and the upper mount.
Inspect the strut for leaks or damage; replace if necessary.
Install the new strut, ensuring all bolts are torqued to manufacturer specifications (refer to service manual).
Reassemble the wheel and lower the vehicle.

3. Check and Replace Bushings

Tools Required: Socket set, pry bar, and hammer.
Inspect control arm bushings for wear.
If worn, use a pry bar to remove old bushings and press in new bushings using a suitable tool.
Ensure all bushings are securely fastened.

4. Tighten Loose Components

Tools Required: Socket set and torque wrench.
Check all suspension bolts and nuts for tightness.
Use a torque wrench to tighten to specified torque values as per the service manual.

5. Final Inspection

Recheck all components and ensure no tools are left in the engine bay.
Reconnect the battery.
