Diagnostic Steps

1
Inspect brake rotors for warping using a runout gauge or dial indicator.
2
Check brake pads for wear and proper installation.
3
Examine wheel lug nut torque to ensure they are properly tightened.
4
Verify the condition of the suspension components, such as control arms and bushings.
5

Solution

1. Preparation

Gather tools and safety gear.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, runout gauge.
Sub-steps:
1. Loosen the lug nuts on the front wheels using a socket set.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the front wheels.
4. Use a runout gauge to check for rotor warping. If the runout exceeds specifications, replace the rotors.
5. If replacing, remove the caliper and bracket, then install new rotors, ensuring they are clean and free of debris. Torque the caliper bolts to manufacturer specifications.

3. Inspect and Replace Brake Pads

Tools Required: Piston tool, brake grease.
Sub-steps:
1. Remove the brake caliper from the rotor.
2. Check the brake pads for wear. Replace if they are below the minimum thickness.
3. Apply brake grease to the back of new pads to prevent noise and ensure smooth operation.
4. Reinstall the caliper over the new pads and torque bolts to specifications.

4. Check Wheel Alignment

Tools Required: Alignment equipment (if performing alignment), or take to a professional.
Sub-steps:
1. If alignment is off, adjust the camber, caster, and toe angles as necessary.
2. Professional equipment may be required to ensure proper alignment settings are achieved.
