Solution

1. Tire Inspection and Balancing

Inspect Tires: Check for any signs of uneven wear, bulges, or punctures.
Balance Tires: If tires are found to be unbalanced, use a tire balancing machine to correct the weight distribution.

2. Wheel Alignment

Perform Alignment: If the alignment is off, use a wheel alignment machine to adjust the angles of the wheels per manufacturer specifications.

3. Driveshaft and CV Joint Inspection

Inspect Driveshaft: Look for any visible damage or excessive play in the driveshaft.
Check CV Joints: If the CV joints are damaged, replace them as necessary. Remove the wheel and axle nut, detach the CV joint from the hub, and replace it with a new component.

4. Engine and Transmission Mounts

Inspect Mounts: Check engine and transmission mounts for cracks or signs of wear.
Replace if Necessary: If mounts are damaged, use appropriate tools to remove the old mounts and install new ones, ensuring they are torqued to specified values.

5. Suspension Component Check

Inspect Suspension: Look for worn or damaged struts, shocks, or bushings.
Replace Worn Parts: If any components are worn, replace them with new parts, ensuring correct torque specifications are followed during installation.
