Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use jack stands to elevate and secure the vehicle safely.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel with a lug wrench.
2. Remove the caliper bolts using a socket set and secure the caliper to avoid strain on the brake line.
3. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
4. Check for warping using a dial indicator; if warped, replace the rotors.
5. Install new rotors, securing them with retaining screws.
Tools Required:
- Lug wrench
- Socket set
- Dial indicator

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper and rotor as outlined in the previous step.
2. Inspect the brake pads for thickness; they should be at least 1/4 inch thick.
3. If worn unevenly or below the minimum thickness, replace the brake pads.
4. Apply brake grease to the back of the new pads and install them.
Tools Required:
- Brake pad spreader tool
- Brake grease

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and struts for cracks or excessive wear.
2. Replace any worn or damaged components, ensuring proper torque specifications are followed.
Tools Required:
- Torque wrench
- Socket set

5. Wheel Balancing and Alignment

Sub-steps:
1. Remove the wheels and take them to a tire shop for balancing.
2. After balancing, perform a wheel alignment to ensure proper tracking.
Tools Required:
- Alignment equipment (typically found at tire shops)
