Solution

1. Tire Inspection and Replacement

Inspect Tires:
- Check all tires for uneven wear, bulges, or other damage.
Replace Tires (if necessary):
- Remove flat or damaged tires using a jack and lug wrench.
- Install new tires, ensuring they are properly inflated according to the manufacturer's specifications.

2. Wheel Alignment and Balancing

Alignment:
- Use an alignment machine to check and adjust the alignment according to the manufacturer’s specifications.
Balancing:
- Remove the wheel assemblies.
- Use a wheel balancing machine to ensure weights are applied correctly.

3. Drivetrain Component Inspection

CV Joint and Driveshaft:
- Inspect CV joints for wear; replace if torn or damaged.
- Check driveshaft for straightness; replace if bent or damaged.

4. Engine and Transmission Mount Inspection

Mount Inspection:
- Visually inspect mounts for cracks or signs of excessive wear.
Replacement:
- Remove the damaged mounts using a socket set.
- Install new mounts, ensuring they are torqued to manufacturer specifications.

5. Transmission Fluid Check

Fluid Level:
- Check the transmission fluid level using the dipstick; top off with the correct type of fluid if low.
Fluid Condition:
- If the fluid is dark or smells burnt, consider a transmission fluid change.
