Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if electrical components will be worked on.

2. Tire Inspection and Balancing

Sub-steps:
- Remove the wheels using a socket set.
- Visually inspect tires for bulges, blisters, or uneven wear.
- Measure and adjust tire pressure to manufacturer's specifications.
- Mount the tires on a wheel balancer to check for imbalance.
- Add balancing weights as needed to correct any imbalance.

3. Wheel Alignment

Sub-steps:
- Position the vehicle on an alignment rack.
- Use alignment tools to measure the angles of the wheels.
- Adjust the camber, toe, and caster settings to meet manufacturer specifications.
- Test drive the vehicle to confirm improvement in handling and vibration.

4. Suspension Component Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect control arms, bushings, struts, and shocks for signs of wear or damage.
- Replace any worn or damaged components following the manufacturer's guidelines.
- Reassemble the suspension parts ensuring all bolts are torqued to specifications.

5. Driveshaft Inspection

Sub-steps:
- Check the driveshaft for any signs of bend or damage.
- Inspect U-joints for play or wear by rocking them back and forth.
- If any issues are found, replace the driveshaft or U-joints as necessary.
