Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Ensure the engine is off and cool.

2. Inspect and Replace Suspension Components

Visual Inspection
- Use a jack and jack stands to lift the vehicle.
- Inspect all suspension components, including control arms, bushings, and shocks for any signs of wear or damage.
Replace Damaged Parts
- If any component is worn, remove the affected part using a socket set.
- Replace with OEM or high-quality aftermarket parts, ensuring all bolts are torqued to manufacturer specifications.

3. Brake Inspection and Service

Brake Pad and Rotor Inspection
- Remove the wheel using a lug wrench.
- Inspect brake pads for thickness and check for any uneven wear patterns.
- Check the rotors for scoring or warping.
Replace Brake Components
- If pads are worn below specifications, remove the caliper and replace pads.
- Resurface or replace rotors as necessary, ensuring to follow torque specifications for caliper bolts.

4. Drive Belt Inspection

Belt Check
- Inspect the drive belt for cracks or signs of wear.
- Check alignment of pulleys.
Replace if Necessary
- If the belt is worn, remove it using a serpentine belt tool.
- Install a new belt, ensuring correct routing and tension.

5. Wheel Bearing Inspection

Check Wheel Bearings
- Raise the vehicle and grasp the wheel at the 12 and 6 o'clock positions.
- Check for play; if excessive movement is felt, the bearing may need replacement.
Replace Wheel Bearings
- Remove the hub assembly as needed using a socket set.
- Replace with new bearings and reassemble, torquing bolts to specification.
