Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the front wheels using a lug wrench.
2. Unbolt the brake caliper and suspend it with a wire to avoid stress on the brake line.
3. Remove the brake pads for access to the rotor.
4. Measure rotor thickness with calipers; replace if below manufacturer specifications.
5. Check rotor surface for warping using a dial indicator; replace if warped.
6. Install new rotors, ensuring proper torque according to manufacturer specifications (typically 70-90 lb-ft).
7. Reinstall brake pads and caliper.

3. Inspect and Replace Suspension Components if Necessary

Sub-steps:
1. Visual inspection of tie rods, control arms, and bushings for wear or damage.
2. Replace any damaged components using appropriate tools (socket set, torque wrench).
3. Recheck the alignment of the wheels after replacement.
