Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use jack stands to safely elevate the vehicle if necessary.

2. Inspect and Replace Shocks/Struts

Tools Required: Socket set, torque wrench, spring compressor (if necessary), pry bar.
Remove the wheel by loosening the lug nuts and lifting the vehicle.
Disconnect the shock absorber or strut from the mounting points using the socket set.
If the strut is damaged, use a spring compressor to safely remove the coil spring from the strut assembly.
Replace with a new shock absorber or strut, following manufacturer specifications for torque values during reinstallation.
Reattach the wheel and lower the vehicle.

3. Replace Bushings (if necessary)

Tools Required: Socket set, bushing tool or press.
Remove the suspension component (e.g., lower control arm) where the bushing is located.
Use the bushing tool to press out the old bushing and press in the new bushing.
Reinstall the suspension component and ensure all bolts are torqued to specifications.

4. Inspect and Tighten Loose Components

Tools Required: Wrench set.
Check all suspension-related bolts and nuts for tightness.
Tighten any loose components found during the inspection to the manufacturer's specifications.
