Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Replace Brake Components

Remove the Wheel
- Use a lug wrench to loosen the lug nuts and lift the vehicle using a jack.
- Secure it with jack stands and remove the wheel.
Inspect Brake Pads and Rotors
- Check the brake pads for thickness; replace if less than 3mm.
- Inspect rotors for warping or scoring; replace or resurface if necessary.
- Tools Required: Brake caliper tool, torque wrench.
Replace Brake Pads and Rotors
- Remove the brake caliper and bracket using a socket set.
- If rotors are being replaced, remove the rotor from the hub.
- Install new rotors and pads in reverse order, ensuring proper alignment.
- Torque caliper bolts to specified manufacturer settings (typically around 25-35 ft-lbs).

3. Check Engine and Transmission Mounts

Inspect Engine and Transmission Mounts
- Visually inspect mounts for cracks or excessive wear.
- Use a pry bar to check for excessive movement in the mounts.
Replace Worn Mounts
- If mounts are damaged, support the engine/transmission with a jack.
- Remove the old mounts and install new ones.
- Torque bolts to manufacturer specifications.
- Tools Required: Jack, jack stands, socket set.
