Solution

1. Preparation

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

2. Inspect and Replace Brake Rotors

Remove the Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Check Rotor Condition
- Visually inspect the rotor surface for grooves, warping, or uneven wear.
- Use a dial indicator to measure rotor runout if needed.
Replace Rotor (if warped)
- Remove caliper bolts and slide the caliper off the rotor.
- Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
- Install the new rotor, ensuring it sits flush against the hub.

3. Inspect and Replace Brake Pads

Check Brake Pad Condition
- Examine the brake pads for thickness and even wear.
- If the pads are worn unevenly, they should be replaced.
Replace Brake Pads (if necessary)
- Remove the caliper from the rotor.
- Slide out the old pads and replace them with new ones.
- Reinstall the caliper, ensuring all bolts are tightened to the manufacturer's torque specifications.

4. Inspect Suspension Components

Visual Inspection
- Check for any visible damage to the control arms, bushings, and ball joints.
Test for Play
- With the wheel off, grasp the wheel at 12 and 6 o'clock positions and wiggle. Any play indicates worn components.
Replace Worn Parts
- If any components are found to be damaged, replace them following manufacturer specifications.
