Solution

1. Preparation

Gather Tools: OBD-II scanner, jack and jack stands, torque wrench, socket set, tire pressure gauge.
Safety Warning: Always ensure the vehicle is on a flat surface and securely supported on jack stands before working underneath.

2. Tire and Wheel Inspection

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's specifications.
Visual Inspection: Inspect each tire for bulges, cuts, or uneven wear.
Wheel Balance: If tires appear normal, have them balanced by a professional.

3. Mounts Replacement

Locate Mounts: Identify the engine and transmission mounts under the vehicle.
Remove Fasteners: Use a socket set to remove the bolts securing the mounts.
Replace Mounts: Install new mounts and torque to the manufacturer's specifications (consult repair manual for torque values).

4. Driveshaft and CV Joint Inspection

Visual Inspection: Check the driveshaft and CV joints for any visible damage or tears in the rubber boots.
Spin Test: Rotate the driveshaft by hand to ensure it moves freely without binding or grinding sounds.
Replace as Necessary: If damage is found, replace the affected components following manufacturer guidelines.

5. Suspension Components Check

Visual Inspection: Check control arms, bushings, and struts for wear.
Shake Test: With the vehicle on jack stands, shake the wheel to check for excessive play.
Replace Worn Parts: If any components are found to be worn, replace them as needed according to specifications.
