Solution

1. Preparation

Tools Required: Jack and jack stands, tire iron, OBD-II scanner, torque wrench, wheel balancer.
Ensure the vehicle is on a flat surface and the engine is off. Disconnect the battery for safety.

2. Tire Inspection and Balancing

Remove the wheel covers and loosen the lug nuts slightly.
Jack up the vehicle and secure it with jack stands.
Remove the wheels and inspect for uneven wear, bulges, or punctures.
Check tire pressure and inflate to manufacturer specifications.
Have tires balanced at a professional shop, if necessary.

3. Driveshaft Examination

Locate the driveshaft and inspect for any signs of damage, such as cracks or dents.
Check the universal joints for play. If worn, replace them with new units.
Ensure all mounting bolts are torqued to the manufacturer’s specifications.

4. Suspension Check

Inspect control arms, bushings, and shock absorbers for wear or damage.
Replace any worn components with OEM or high-quality aftermarket parts.
Reassemble and torque bolts to the manufacturer’s specifications.

5. Engine and Transmission Mounts Inspection

Locate the engine and transmission mounts and visually inspect them for cracks or deterioration.
If any mounts are found to be defective, remove the old mounts and install new ones, ensuring proper alignment and torque.
