Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shocks.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
- Remove the wheel covers or hubcaps (if applicable).
- Loosen the lug nuts with a socket wrench.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheels and inspect the tires for uneven wear or damage.
- If tires are damaged or excessively worn, replace them with new tires, ensuring they match the specifications.
- Reinstall wheels and tighten lug nuts to the manufacturer’s torque specifications (usually around 80-100 lb-ft, check specific values for your model).

3. Check and Adjust Wheel Alignment

Sub-steps:
- Use a wheel alignment tool or take the vehicle to a professional alignment shop.
- Adjust alignment settings according to manufacturer specifications.
- Test drive the vehicle to confirm that the shaking has been resolved.

4. Inspect and Replace Driveshaft (if necessary)

Sub-steps:
- Remove any necessary underbody covers to access the driveshaft.
- Inspect the driveshaft for any visible damage, such as dents or bends.
- Check universal joints for play or wear.
- If damage is found, replace the driveshaft, ensuring to align it correctly during installation.

5. Check and Replace Engine/Transmission Mounts (if necessary)

Sub-steps:
- Locate the engine and transmission mounts under the vehicle.
- Inspect mounts for cracks, separations, or excessive wear.
- If mounts are damaged, remove the old mounts and install new ones, ensuring proper torque is applied according to manufacturer specifications.
