Solution

1. Preparation

Gather tools and parts needed for the repair.
Safety: Disconnect the battery before starting any work.

2. Inspect and Replace Engine/Transmission Mounts

Locate the engine and transmission mounts:
- Use a socket set to remove any covers obstructing access.
Check for damage:
- Inspect each mount for cracks, tears, or excessive wear.
Remove worn mounts:
- Use a wrench to unbolt the mounts from the engine and chassis.
- Carefully support the engine/transmission with a jack before removal.
Install new mounts:
- Position the new mounts in place and hand-tighten the bolts.
- Torque to manufacturer specifications (usually around 40-70 ft-lbs, consult service manual for exact values).

3. Wheel Alignment and Balancing

Inspect tires for balance:
- Take the vehicle to a tire shop to confirm that tires are balanced correctly.
Check alignment:
- Have a professional perform a wheel alignment to ensure all angles are set to specifications.

4. Inspect and Replace CV Joints/Driveshaft
