Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the vehicle battery to prevent electrical issues during repair.

2. Inspect and Replace Brake Pads and Rotors

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, C-clamp or brake caliper tool.
Lift the vehicle using a jack and secure with jack stands.
Remove the wheel using a lug wrench.
Inspect brake pads and rotors for wear. If they are worn or warped:
- Remove the caliper bolts and slide the caliper off the rotor.
- Remove the old brake pads.
- Use a C-clamp or brake caliper tool to compress the caliper piston.
- Install new brake pads and reattach the caliper.
- Replace the rotor if warped, by unscrewing the rotor retaining screws and sliding it off.
- Install the new rotor and secure it with screws.

3. Check and Replace Suspension Components

Tools Required: Socket set, torque wrench, pry bar.
Inspect control arms, tie rods, and bushings for damage. Replace any components that are loose or worn.
Use a pry bar to check for play in the bushings and joints.
If a component needs replacement, remove the bolts securing the component, replace it, and torque to manufacturer specifications.

4. Wheel Alignment

Tools Required: Wheel alignment tool.
After replacing any suspension parts, perform a wheel alignment.
Adjust the camber, caster, and toe settings to manufacturer specifications.
