Solution

1. Tire Inspection and Balancing

Remove the wheel: Use a jack to lift the vehicle and secure it with jack stands.
Inspect tires: Check for uneven wear, damage, or bulges in the sidewalls.
Balance tires: If tires are in good condition, take them to a tire shop for balancing. Ensure weights are properly applied.
Reinstall the wheel: Torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

2. Wheel Alignment

Perform alignment check: Take the vehicle to a professional alignment shop.
Adjust alignment angles: Ensure camber, caster, and toe settings are within specifications.

3. Driveshaft and CV Joint Inspection

Lift the vehicle: Use a jack and jack stands to safely elevate the vehicle.
Inspect driveshaft: Look for any visible damage or excessive play in the joints.
Check CV joints: Look for torn boots or grease leakage; replace if damaged.

4. Suspension Component Examination

Visual inspection: Check for worn or damaged bushings, control arms, and struts.
Replace worn components: If any parts are found to be faulty, replace with OEM or quality aftermarket parts.

5. Brake System Check

Inspect brake components: Verify that calipers are functioning properly and not binding.
Replace brake pads or rotors: If any wear or damage is present, replace as necessary.
