Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks for safety.
Disconnect the battery if working on the brake system.

2. Inspect and Replace Brake Rotors

Lift the Vehicle: Use a jack to lift the front or rear (depending on where the shaking occurs) and secure it with jack stands.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect Rotors: Check the rotors for warping using a dial indicator or caliper. If warping is detected beyond manufacturer's specifications (usually more than 0.002 inches), proceed to replace.
Remove Brake Caliper: Use a socket set to unbolt the caliper and hang it securely without stressing the brake line.
Remove Rotor: If necessary, remove the rotor retaining screws, then slide off the rotor from the hub.
Install New Rotor: Place the new rotor onto the wheel hub. Torque the rotor retaining screws to the manufacturer's specifications (typically around 10-15 lb-ft).
Reattach Caliper: Reinstall the brake caliper and torque bolts to the manufacturer’s specifications (usually around 20-25 lb-ft).

3. Inspect and Replace Brake Pads

Remove Old Pads: Remove the old brake pads from the caliper bracket; note the orientation for new pads.
Install New Pads: Apply anti-squeal grease to the back of the new pads and install them in the same orientation as the old pads.
Reassemble Caliper: Compress the caliper piston using a C-clamp to allow for the new pads, then reattach the caliper.

4. Check and Replace Suspension Components (if necessary)

Inspect Control Arms and Bushings: Check for cracks or excessive wear. Replace if necessary.
Replace Worn Bearings: If wheel bearings are found to be damaged, remove the hub assembly and replace the bearings according to the manufacturer's specifications.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
C-clamp
Dial indicator or caliper
Anti-squeal grease

Parts Required:

New brake rotors
New brake pads
Suspension components (if needed)
Wheel bearings (if needed)

Estimated Repair Time: 2-4 hours

Safety Warnings:
