Solution

1. Preparation

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

2. Inspect and Replace Brake Components

Remove Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove lug nuts with a socket set and take off the wheel.
Inspect Brake Pads and Rotors
- Check the thickness of the brake pads; replace if below manufacturer specifications (usually 3 mm).
- Inspect rotors for warping or scoring. If warped, resurface or replace rotors.
Check Brake Calipers
- Inspect caliper slides for proper movement. If stuck, clean, lubricate, or replace the caliper as necessary.
Reassemble Brake Components
- If any components were replaced, reassemble in reverse order. Ensure proper torque settings for lug nuts (typically 100-120 lb-ft).

3. Suspension Inspection and Adjustment

Examine Suspension Components
- Inspect control arms, bushings, and tie rod ends for any signs of wear or damage.
- Replace any worn components as necessary.
Check Wheel Alignment and Balance
- Use a wheel alignment machine to ensure proper alignment settings according to manufacturer specifications.
