Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, tire pressure gauge, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Check Tire Pressure: Use a tire pressure gauge to verify that all tires are inflated to the manufacturer's recommended PSI.
Examine Tire Condition: Look for uneven wear patterns; replace tires if necessary.
Torque Lug Nuts: If tires were removed, use a torque wrench to ensure lug nuts are tightened to the manufacturer’s specifications.

3. Suspension Component Replacement

Identify Worn Parts: Determine if any bushings or control arms are damaged.
Remove Affected Components: Use a socket set to detach any worn suspension parts.
Install New Components: Replace with OEM or quality aftermarket parts, ensuring all bolts are torqued to specifications.

4. Drivetrain Inspection and Repair

Inspect Drive Unit: Look for any oil leaks or damage to motor mounts.
Tighten or Replace Motor Mounts: If motor mounts are loose or damaged, replace them, ensuring they are properly torqued.
Check Connections: Ensure all electrical and mechanical connections to the drive unit are secure.

5. Brake Component Maintenance

Inspect Brake Calipers: Ensure they are not sticking; clean or replace as necessary.
Check Brake Pads: Replace worn brake pads to ensure proper function.
Bleed Brake System: If calipers were removed, bleed the brake lines to remove any air.
