Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack and jack stands, torque wrench
Check tire pressure and inflate to manufacturer's specifications if needed.
Inspect tires for damage or uneven wear; replace if necessary following these sub-steps:
- Loosen wheel lug nuts slightly while on the ground.
- Raise the vehicle using a jack and secure with jack stands.
- Remove the lug nuts and take off the wheel.
- Replace with a new tire, ensuring it’s properly seated on the rim.
- Reinstall the lug nuts and tighten to the manufacturer’s torque specification.
- Lower the vehicle and fully tighten the lug nuts in a star pattern.

3. Wheel Balancing and Alignment

Tools Required: Wheel balancer, alignment tools
If tires are in good condition, proceed to balance:
- Remove the wheel from the vehicle and mount it on the wheel balancer.
- Follow the machine instructions to achieve proper balance; add weights as needed.
- Reinstall the wheel on the vehicle.
Check alignment:
- Adjust wheel alignment using an alignment machine following the manufacturer's specifications.

4. Inspection and Replacement of Mounts/Drivetrain Components

Tools Required: Socket set, torque wrench, pry bar
Inspect engine and transmission mounts:
- Remove any components obstructing access to mounts.
- Check for cracks or excessive wear in the rubber isolators.
- Replace damaged mounts using the following sub-steps:
  - Support the engine or transmission with a jack.
  - Remove the bolts securing the mount, then replace with new mount.
  - Torque bolts to manufacturer specifications.
Inspect CV joints and drive shafts:
- Look for torn boots or grease leakage.
- Replace any damaged components as necessary.
