Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle with a jack and support it with jack stands.

2. Inspect and Replace Damaged Components

Sway Bar Links:
- Remove the retaining nuts with a socket set and replace the sway bar links if worn.
Shock Absorbers/Struts:
- Disconnect the upper and lower mounting bolts using a socket set.
- Carefully remove the shock absorber or strut assembly.
- Replace with new units following manufacturer specifications for torque settings.
Control Arm Bushings:
- Remove the control arm by disconnecting bolts using a torque wrench.
- Inspect bushings for wear and replace if necessary.

3. Reassemble and Lower Vehicle

Reattach all components in the reverse order of removal.
Ensure all bolts are torqued to specifications.
Lower the vehicle carefully back to the ground and remove the jack stands.
