Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on the braking system.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Brake Pads

Remove the wheels to access the brake components.
Inspect the brake pads for uneven wear. If worn beyond specifications (usually 3mm or less), replace them.
- Tools Required: Socket set, torque wrench.
- Safety Warning: Ensure the vehicle is secure on jack stands before working.

3. Check and Resurface or Replace Brake Rotors

Use a dial gauge to measure the rotor thickness and check for warping. If warping exceeds manufacturer specifications (typically 0.002 inches), the rotor should be resurfaced or replaced.
- Remove the brake caliper and rotor.
- If resurfacing, follow the machine’s instructions; if replacing, install new rotors.
- Tools Required: Socket set, brake caliper tool.

4. Inspect and Replace Wheel Bearings

Check for play in the wheel bearings by moving the wheel back and forth. If there is excessive play, replace the wheel bearings.
- Remove the wheel hub assembly to access bearings.
- Replace with new bearings and reassemble.
- Tools Required: Bearing puller, socket set.

5. Check Suspension Components

Inspect control arms and bushings for any signs of wear or damage.
Replace any worn parts to ensure proper alignment and handling.
- Tools Required: Socket set, pry bar.
