Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.

2. Tire Inspection

Tools Required: Tire pressure gauge, lug wrench
Check the tire pressure and adjust to manufacturer specifications. Inspect tires for uneven wear or damage.
Replace any damaged tires as needed.

3. Brake Inspection

Tools Required: Lug wrench, jack stands, brake cleaner
Remove the wheel to access the brake components.
Inspect brake calipers for sticking or binding. Clean and lubricate moving parts as necessary.
Replace brake pads if they show signs of excessive wear or damage.

4. Drivetrain Examination

Tools Required: Socket set, torque wrench
Inspect the driveshaft for any signs of wear or damage. Check universal joints for play.
If any components are damaged, replace them with OEM parts. Torque bolts to manufacturer specifications during reassembly.

5. Suspension Check

Tools Required: Socket set, pry bar
Inspect the suspension components, including control arms, bushings, and shocks. Look for signs of wear or damage.
Replace any worn components and ensure all fasteners are tightened to specifications.
