Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine and Transmission Mounts

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Visually inspect the engine and transmission mounts for cracks or separation.
3. If damaged, proceed to replace mounts using a socket set.
4. Torque new mounts to manufacturer specifications (typically found in the repair manual).

3. Examine Driveshaft and CV Joints

Sub-steps:
1. Inspect the driveshaft and CV joints for any signs of wear or damage (such as tears in the boot or play in the joints).
2. If damaged, remove the driveshaft using appropriate tools and replace with a new unit.
3. Ensure all bolts are torqued to specifications.

4. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure and condition; look for uneven wear or bulges.
2. Rotate or replace tires if necessary to ensure even wear.
3. Balance the wheels if vibrations persist after other repairs.

5. Transmission Fluid Check

Sub-steps:
1. Remove the transmission pan to inspect fluid condition.
2. If fluid is burnt or contaminated, drain and replace fluid with manufacturer-recommended fluid type.
3. Replace the transmission filter if applicable.
