Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle's 12V battery for safety.

2. Inspect and Replace Brake Pads and Rotors

Remove the wheel:
- Loosen lug nuts using a socket wrench.
- Lift the vehicle with a jack and secure with jack stands.
- Remove the wheel.
Inspect brake components:
- Visually check brake pads for uneven wear.
- Measure rotor thickness using a caliper and check for warping with a runout gauge.
Replace brake pads (if necessary):
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and support it without putting stress on the brake line.
- Remove old brake pads and install new ones, ensuring they are seated properly.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Replace rotors (if necessary):
- Remove the rotor by unscrewing any retaining screws.
- Install the new rotor and secure it with retaining screws.
- Reinstall the wheel and torque lug nuts to manufacturer specifications (typically around 100-120 ft-lbs).

3. Check Suspension Components

Inspect control arms, struts, and bushings:
- Look for signs of wear or damage, such as cracks or excessive play.
Replace any worn components:
- Remove and replace faulty struts or control arms as necessary, following manufacturer specifications.

4. Wheel Alignment

Check alignment settings:
- Use an alignment machine to check the vehicle's alignment.
Adjust as needed:
- Make necessary adjustments to camber, toe, and caster settings according to manufacturer specifications.
