Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, jack, jack stands, tire balancer.
Check tire pressures using the pressure gauge and adjust as necessary.
Inspect all tires for uneven wear, bulges, or punctures. Replace any damaged tires.
Use a tire balancer to balance the tires if they are out of balance.

3. Drivetrain Inspection

Tools Required: Jack, jack stands, socket set.
Safely lift the vehicle and support it with jack stands.
Inspect the driveshaft for any signs of bending, cracks, or damage.
Check CV joints for wear by visually inspecting for torn boots or grease leakage.

4. Engine and Transmission Mount Inspection

Tools Required: Socket set, torque wrench.
Locate the engine and transmission mounts, inspecting for cracks or excessive wear.
If any mounts are faulty, replace them by removing the old mount bolts and installing new mounts to the manufacturer’s torque specifications.

5. Test Drive

After completing repairs, lower the vehicle and reconnect the battery.
Conduct a test drive to ensure the shaking has been resolved during acceleration.
