Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Wear safety goggles and gloves.

2. Tire Inspection and Replacement

Remove the lug nuts using a socket set and jack the vehicle to access the tires.
Inspect each tire for uneven wear patterns and check the pressure; replace any tires that are worn beyond the tread indicators.
If replacing a tire, ensure the new tire is of the same size and type as the others.

3. Wheel Balancing

After ensuring tire integrity, take the vehicle to a tire shop to have the wheels balanced.
Follow the technician's instructions for balancing; typically, they will add weights to the rim as needed.

4. Suspension Inspection and Repair

With the vehicle elevated, visually inspect the suspension components for any visible damage.
If any control arms or bushings are worn, replace them with OEM or high-quality aftermarket parts.
- Use a torque wrench to tighten to manufacturer specifications (usually specified in the vehicle manual).

5. Drivetrain Inspection and Repair

Inspect the driveshaft for any signs of damage, such as dents or excessive play in the joints.
If any issues are found, replace the driveshaft or CV joints as necessary.
Ensure all components are properly lubricated and torqued to the manufacturer's specifications.
