Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner, WD-40 or silicone spray.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks before lifting.

2. Brake System Repair

Inspect Brake Pads: Remove the wheel to access the brake assembly.
- Check the thickness of the brake pads; if less than 3mm, replace them.
Clean Components: Use brake cleaner to remove dust and debris from the brake pads and rotors.
Lubricate: Apply silicone lubricant to the brake caliper contact points and back of the pads.

3. Suspension Component Repair

Inspect Suspension Parts: Remove the wheel for a full view of the suspension.
- Look for any cracked or worn bushings, struts, or control arms.
Replace Worn Components: If any components are damaged, replace them with OEM or high-quality aftermarket parts.
Tighten Loose Bolts: Ensure all bolts and nuts are properly torqued to manufacturer specifications.

4. Test Drive

Reassemble the wheel and lower the vehicle.
Conduct a test drive to verify that the squeaking noise has been eliminated.
