Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety during repairs.

2. Tire Inspection and Balancing

Check Tire Condition:
- Inspect each tire for signs of damage, uneven wear, or low pressure.
- Replace any damaged tires.
Balance Tires:
- Remove the wheels using a socket set.
- Take the wheels to a tire shop for balancing or use a wheel balancer if available.
- Reinstall the wheels and torque the lug nuts to specifications (typically 75-90 ft-lbs for Tiguan).

3. Inspect and Replace CV Joints or Axles

Visual Inspection:
- Look for torn CV boot covers or leaks around the CV joints.
Replacement (if necessary):
- Remove the axle nut using a breaker bar.
- Disconnect the lower control arm to free the axle.
- Carefully remove the CV joint and replace it with a new one.
- Reinstall the axle and torque the axle nut to manufacturer specifications.

4. Check Engine and Transmission Mounts

Inspect Mounts:
- Visually inspect the mounts for cracks or deterioration.
Replacement:
- Remove bolts securing the mount to the engine and frame.
- Replace with new mounts and torque the bolts to specifications.
