Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical shorts while working.
Tools Required: Socket set, wrenches, belt tension gauge, safety gloves.

2. Inspect and Replace Drive Belts

Inspect the belts: Check for any signs of cracking, fraying, or misalignment.
Remove old belts: Loosen the tensioner using a wrench, then slide the belt off the pulleys.
Install new belts: Route the new belt according to the diagram usually found on a sticker in the engine bay. Ensure proper tension is applied.
Torque specifications: Refer to the service manual for proper torque settings on the tensioner.

3. Check and Replace Tires (if necessary)

Inspect tires: Look for signs of uneven wear, bulges, or damage.
Replace tires: If damaged, use a jack to lift the vehicle and remove the wheel lug nuts with a socket wrench, then replace the tire and secure it with lug nuts torqued to manufacturer specifications.

4. Inspect and Address Other Rubber Components

Inspect hoses and gaskets: Look for cracks or leaks in any rubber hoses or gaskets.
Replace damaged components: Remove any damaged hoses or gaskets and install new parts, ensuring proper fit and sealing.
