Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Brake Components

Check Brake Rotors:
- Remove the wheel using a socket set.
- Inspect the rotors for warping with a dial indicator; replace if warped beyond specifications (typically 0.002 inches).
- If rotors are within spec but have uneven wear, consider resurfacing or replacing them.
Replace Brake Pads:
- If pads are worn down to a thickness of less than 3mm, replace them.
- Remove the caliper by unbolting it from the bracket; hang it securely without stressing the brake line.
- Remove old pads and install new pads, ensuring proper orientation and alignment.

3. Check and Replace Suspension Components

Inspect Control Arms and Bushings:
- Visually inspect control arms and bushings for cracks, tears, or excessive wear.
- If damaged, remove the affected component using an appropriate socket or wrench.
- Replace bushings if necessary, and reassemble.
Check Wheel Bearings:
- Lift the vehicle and check for play in the wheel hub by shaking it side to side.
- If play is detected, remove the wheel and hub assembly, and replace the wheel bearings.

4. Tire Inspection and Balancing

Inspect tires for uneven wear, bulges, or low tread.
If tires are damaged or worn, replace them.
Balance the tires if needed to ensure even weight distribution.
