Solution

1. Preparation

Tools Required: Jack and jack stands, tire pressure gauge, tire balancing machine, alignment machine, basic hand tools.
Safety Warnings: Ensure the vehicle is parked on a level surface and set the parking brake before beginning work.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate as necessary to match the manufacturer’s specifications.

3. Inspect and Balance Tires

Remove the wheels using a socket set.
Visually inspect tires for damage or uneven wear.
Mount the tires on a tire balancing machine and adjust weights as needed.

4. Perform Wheel Alignment

After balancing, mount the wheels back on the vehicle.
Use an alignment machine to check and adjust the alignment to manufacturer specifications.

5. Inspect and Replace Suspension Components (if necessary)

Check for any worn or damaged components in the suspension.
If any parts are found defective, replace them as follows:
- Ball Joints: Use a ball joint separator to remove and replace if necessary.
- Control Arms and Bushings: Remove bolts and replace with new components, ensuring proper torque specifications.

6. Inspect Driveshaft and CV Axles

Check for any play in the driveshaft and CV joints.
If damaged, replace the driveshaft or CV axle as follows:
- Remove the retaining bolts and disconnect from the differential/transmission.
- Install the new part and torque the bolts to manufacturer specifications.
