Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and safely elevate it using a hydraulic jack and jack stands.
Disconnect the negative battery terminal to eliminate any electrical hazards.

2. Inspect and Replace Suspension Components

Inspect Struts and Shocks:
- Remove wheels to access struts and shocks.
- Check for oil leakage on struts or shocks, indicating failure.
- If damaged, proceed to replace them with new units.
Replace Worn Bushings and Sway Bar Links:
- Use a socket set to disconnect the sway bar links from the sway bar and control arms.
- Remove old bushings and replace them with new ones.
- Reconnect the sway bar links ensuring they are tightened to manufacturer specifications.

3. Check and Tighten Suspension Bolts

Use a torque wrench to check and tighten all suspension bolts to the specified torque values as per manufacturer specifications.
Ensure all components are secure and properly aligned.

4. Verify Drivetrain Components

Inspect the drivetrain for any loose bolts or components around the transfer case and rear differential.
Tighten any loose connections, and replace worn mounts if necessary.
