Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure.
Disconnect the battery for safety if electrical components will be handled.

2. Tire Inspection and Adjustment

Check tire pressure and inflate to the manufacturer's recommended PSI.
Inspect tires for uneven wear; replace if necessary.
Balance the tires using a wheel balancer if out of balance.

3. Wheel Alignment

Use a wheel alignment machine to check alignment settings.
Adjust the alignment according to manufacturer specifications.

4. Inspect and Replace CV Joints/Axles (if needed)

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the CV joint and axle.
Inspect the CV boots for tears; replace the axle if any damage is found.
Reinstall the wheel and torque lug nuts to manufacturer specifications.

5. Engine and Transmission Mount Check

Inspect all engine and transmission mounts for cracks or separation.
Replace any damaged mounts with OEM or high-quality aftermarket parts.
Use a torque wrench to tighten mount bolts to the specified torque values.
