Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Inspect and Remove Wheels

Tools Required: Jack, jack stands, lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels by loosening the lug nuts with a lug wrench.

3. Inspect Brake Rotors

Check each rotor for warping using a dial indicator.
If the rotors are warped (exceeding manufacturer specifications), proceed to replace or resurface them.
Replacement:
- Remove caliper bolts and hang the caliper using a bungee cord.
- Remove the rotor by pulling it off the hub.
- Install the new or resurfaced rotor and reattach the caliper.

4. Inspect Brake Pads

Check the brake pads for thickness; replace if less than 3mm remaining.
To replace, remove the caliper as in the previous step.
Slide out the old pads and insert new ones, ensuring they are properly seated.

5. Inspect Suspension Components

Visually inspect control arms, bushings, and tie rods for any signs of wear or damage.
Replace any worn components as necessary.

6. Reassembly and Final Checks

Reattach the wheels and torque the lug nuts to the manufacturer’s specifications (typically 80-100 lb-ft).
Reconnect the negative battery terminal.
Lower the vehicle from the jack stands.
