Disconnect the negative battery terminal to avoid electrical shorts.

2. Fluid Inspection and Replacement

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick or fill plug and check fluid level.
3. If low, add manufacturer-recommended transmission fluid as specified in the owner's manual.
4. If fluid is dirty (dark or burnt smell), drain the transmission fluid.
5. Replace the transmission fluid with fresh fluid, ensuring it meets specifications.

3. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Locate the engine and transmission mounts.
2. Use a socket set to remove the mounting bolts.
3. Inspect mounts for cracks or significant wear.
4. If damaged, install new mounts by aligning them properly and tightening bolts to manufacturer torque specifications.

4. U-Joint and CV Joint Inspection

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Inspect U-joints and CV joints for play and wear.
3. If any joint is damaged, remove the driveshaft and replace the U-joint or CV joint.
4. Reinstall the driveshaft, ensuring proper alignment and torque on bolts.

5. Driveshaft Inspection

Sub-steps:
1. Visually inspect the driveshaft for any signs of damage or misalignment.
2. If misaligned or damaged, realign or replace as necessary.
3. Ensure all connections are tight and secure.
