Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench.
Loosen the wheel lug nuts and lift the vehicle using a jack.
Remove the wheel and inspect the brake rotor visually for warping or uneven wear.
If warped, remove the brake caliper by unscrewing the caliper bolts, then remove the rotor.
Replace with new rotors, ensuring they are properly seated.
Reattach the brake caliper and torque the bolts to the manufacturer’s specifications.

3. Check and Replace Brake Pads

Inspect the brake pads for wear; if they are below the minimum thickness, replace them.
Remove the caliper brackets if necessary to access the pads.
Replace with high-quality brake pads, ensuring they are oriented correctly.
Reassemble the caliper and torque the bolts.

4. Inspect Wheel Bearings and Suspension

Remove the wheel and inspect wheel bearings for play.
If there is excessive play, replace the wheel bearings.
Check suspension components (e.g., control arms, struts) for wear or damage, and replace if necessary.

5. Check Tire Balance and Alignment

Use a tire balance machine to check and balance the tires.
If the alignment is off, take the vehicle to a professional for a wheel alignment.
