Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine Mounts

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove any obstructions to access the engine mounts.
2. Use a socket set to unbolt the engine mounts from the chassis.
3. Inspect for cracks or excessive wear.
4. Replace with new engine mounts if necessary, tightening to manufacturer torque specifications.

3. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel
Sub-steps:
1. Start the engine and let it idle.
2. Remove the transmission dipstick and wipe it clean.
3. Reinsert the dipstick and remove it again to check fluid level.
4. If low, add the recommended transmission fluid.
5. If the fluid is dirty or burnt, consider a transmission fluid change.

4. Inspect Exhaust System

Tools Required: Visual inspection tools (flashlight, mirror)
Sub-steps:
1. Visually inspect the entire exhaust system for loose bolts or damaged hangers.
2. Tighten any loose connections and replace any damaged components.
3. Ensure that there are no leaks present in the exhaust system.

5. Examine Drive Shaft and CV Joints

Tools Required: Jack and jack stands, socket set
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
