Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and cool before starting work.

2. Tire Inspection and Balancing

Remove the wheel covers or hubcaps (if equipped).
Loosen the lug nuts but do not remove them completely.
Lift the vehicle using a jack and secure with jack stands.
Remove the wheels and inspect for uneven wear or damage.
If tires are worn, replace them with new tires of the same specifications.
Balance the tires using a tire balancing machine before reinstallation.

3. Suspension Component Inspection

Visually inspect all suspension components for signs of wear or damage.
Replace any worn or damaged parts (e.g., bushings, control arms).
If necessary, have the alignment checked and adjusted to manufacturer specifications.

4. Driveshaft and CV Joint Inspection

Inspect the driveshaft for any visible damage or excessive play.
Check CV joints for signs of grease leakage or wear.
Replace any damaged driveshaft components or CV joints.

5. Brake Inspection

Check the brake rotors for warping or uneven wear.
Replace warped rotors if necessary and ensure brake pads are in good condition.
Reassemble all components and torque lug nuts to the manufacturer’s specifications.
