Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.

2. Inspect and Replace Drive Belts

Tools Required: Socket set, belt tensioner tool
Steps:
1. Remove the engine cover if necessary to access the drive belts.
2. Use the belt tensioner tool to relieve tension on the drive belt.
3. Inspect the belt for cracks, fraying, or glazing; replace if damaged.
4. Install the new belt, ensuring it is properly seated on all pulleys.
5. Reapply tension to the belt and check for proper alignment.

3. Wheel Bearing and CV Joint Inspection

Tools Required: Jack and jack stands, socket set, hammer
Steps:
1. Lift the vehicle and secure it with jack stands.
2. Remove the wheel to access the CV joint and wheel bearing.
3. Inspect the CV joint for any torn boots or excessive play; replace if damaged.
4. Check the wheel bearing for play by shaking the wheel; replace if it feels loose or makes noise when spun.

4. Suspension Component Inspection

Tools Required: Socket set, pry bar
Steps:
1. With the vehicle still lifted, inspect the shock absorbers and suspension bushings for any signs of leakage or wear.
2. Use a pry bar to check for excessive play in bushings; replace any that are worn or damaged.
3. Reinstall the wheel and lower the vehicle when all inspections and replacements are complete.
