Solution

1. Tire Inspection and Balancing

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels and inspect the tires for uneven wear or damage.
Check tire pressure and adjust to manufacturer specifications.
Balance the wheels using a tire balancer, if necessary.
Reinstall the wheels and lower the vehicle.

2. Driveline Inspection

Inspect the driveshaft for any signs of bending or damage.
Check the CV joints for play or wear by shaking them while the vehicle is raised.
Replace any damaged components. Ensure to torque bolts to manufacturer specifications (typically around 30-50 Nm for CV joint bolts).
If applicable, replace the driveshaft with a new one, ensuring proper alignment during installation.

3. Suspension and Mounts Inspection

Visually inspect all suspension components for visible damage or wear.
Replace any worn or damaged bushings, control arms, or mounts as necessary.
Tighten all fasteners to manufacturer specifications.
If engine or transmission mounts are worn, replace them, ensuring they are torqued to the correct specifications (typically around 40-60 Nm).
