Sub-steps:
1. Lift the vehicle using a floor jack and secure it with jack stands.
2. Inspect suspension components (struts, shocks, bushings) for any visible wear or damage.
3. Replace any worn or damaged components with OEM or high-quality aftermarket parts.
4. Reassemble the suspension and ensure all bolts are torqued to specification.

4. Driveline Inspection and Repair

Sub-steps:
1. Inspect the driveshaft for any signs of damage, such as dents or cracks.
2. Check the CV joints and boot for any tears or leaks.
3. If damaged, replace the driveshaft or CV joint as necessary.
4. Reconnect any disconnected parts and ensure proper alignment and securement.

5. Engine and Transmission Mount Check

Sub-steps:
1. Inspect engine and transmission mounts for any signs of cracking or excessive wear.
