Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery if any electrical components will be handled.

2. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Check tire pressure and inflate to the manufacturer’s specifications.
Remove the wheel and tire assembly using a lug wrench.
Inspect the tires for signs of uneven wear or damage.
If necessary, take the tires to a professional for balancing and alignment.

3. Suspension Component Inspection

Tools Required: Socket set, torque wrench, pry bar.
Visually inspect suspension components such as control arms and bushings for signs of wear or damage.
Use a pry bar to check for excessive play in the bushings and joints.
Replace any worn or damaged parts found during inspection.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, torque wrench, grease.
Inspect the driveshaft and CV joints for cracks, tears, or excessive play.
If damage is found, remove the driveshaft by loosening the bolts at the differential and transmission.
Replace any damaged CV joints or driveshaft components and reassemble.

5. Engine Mount Inspection
