Solution

1. Preparation

Gather tools: jack and jack stands, lug wrench, OBD-II scanner, torque wrench, and basic hand tools.
Ensure the vehicle is on a flat surface and the engine is off before beginning work.

2. Tire Inspection and Balancing

Jack up the vehicle and remove the wheels using the lug wrench.
Inspect all tires for signs of uneven wear, bulges, or damage.
Take the tires to a tire shop for balancing if they show signs of imbalance.
Replace any damaged tires as necessary.

3. Driveshaft Examination and Repair

Inspect the driveshaft by looking for visible damage or signs of wear.
If any damage is found, remove the driveshaft using the appropriate socket set.
Replace the driveshaft if necessary, ensuring the new driveshaft is properly aligned.
Reinstall the driveshaft and torque the bolts to the manufacturer's specifications.

4. Engine and Transmission Mounts Check

Visually inspect the engine and transmission mounts for signs of cracks or deterioration.
If mounts are damaged, use a socket set to remove the faulty mounts.
Replace with OEM or equivalent mounts, ensuring all bolts are torqued to specifications.

5. Wheel Alignment Adjustment

After reinstalling the wheels, take the vehicle to a professional alignment shop.
Ensure the alignment is corrected to prevent further tire wear and vibrations.
