Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and safely lift the vehicle using jack stands.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Inspect Tires: Check for uneven wear, bulges, or damage.
Inflate Tires: Adjust tire pressure to manufacturer's specifications.
Replace Tires: If tires are worn unevenly or damaged, replace with new tires.

3. Wheel Balancing and Alignment

Remove Wheels: Use a lug wrench to remove the wheel from the hub.
Balance Wheels: Mount wheels on a balancing machine and add weights as necessary to achieve balance.
Align Wheels: Adjust the alignment using an alignment machine, following manufacturer specifications for alignment angles.

4. Drivetrain Inspection

Check Driveshaft: Inspect for any visible damage or wear.
Inspect CV Joints: Look for cracks or leaks in the CV boots; replace if necessary.
Replace Damaged Components: If any parts are damaged, replace them with OEM parts.

5. Suspension Component Check

Inspect Bushings and Struts: Check for wear or damage; replace worn suspension parts.
Replace Shocks/Struts: If shocks or struts are leaking or have lost damping capability, replace with OEM or equivalent parts.
