Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Inspect and Replace Worn Belts

Inspect Belts: Remove the engine cover if necessary and visually inspect serpentine and timing belts for signs of wear, cracks, or damage.
Replace Belts:
1. Loosen the tensioner pulley using a socket wrench.
2. Remove the damaged belt.
3. Install the new belt, ensuring it aligns with all pulleys correctly.
4. Re-tension the belt according to manufacturer specifications.

3. Inspect Tires

Inspect Tires: Examine all tires for uneven wear, bulges, or foreign objects stuck in the tread.
Replace Tires:
1. If any tire is damaged, safely jack up the vehicle.
2. Remove the lug nuts using a tire iron and take off the wheel.
3. Install the new tire, hand-tightening the lug nuts.
4. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

4. Check Brake System

Inspect Brakes: Remove the wheel to access the brake caliper. Check for signs of wear on brake pads and any signs of the caliper sticking.
Replace Brake Components:
1. If pads are worn, remove the caliper by loosening the bolts.
2. Replace the brake pads and reassemble the caliper.
3. Ensure proper reinstallation of the wheels.

5. Inspect Wheel Bearings

Check Bearings: With the vehicle raised, spin each wheel to check for roughness or excessive play.
Replace Bearings:
1. Remove the wheel and brake assembly.
2. Use a bearing puller to remove the old bearing and install the new one.
3. Reassemble components and check for smooth operation.
