Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Check brake pads for thickness; replace if less than 3mm.
- Inspect rotors for scoring or warping; replace if necessary.
Replace Brake Pads:
- Remove caliper bolts with a socket wrench.
- Slide caliper off the rotor and support it to avoid stress on the brake line.
- Replace old pads with new pads, ensuring they are properly seated.
Reassemble Brake Components:
- Reattach the caliper and torque the bolts to manufacturer's specifications (typically 25-35 ft-lbs).
- Reinstall the wheel and torque the lug nuts in a star pattern to 80-100 ft-lbs.

3. Inspect and Replace Wheel Bearings

Remove Wheel:
- Follow the same steps as brake inspection.
Check Wheel Bearings:
- With the wheel removed, grasp the rotor and check for play by rocking it back and forth.
Replace Wheel Bearings:
- If play is detected, remove the hub assembly.
- Replace the wheel bearing using a bearing press.
- Reassemble the hub and wheel, ensuring all fasteners are properly torqued.

4. Suspension Inspection

Check Suspension Components:
- Inspect control arms, bushings, and ball joints for wear.
- Replace any damaged components.
