2. Inspect Engine Mounts

Remove any covers obstructing access to the engine mounts.
Visually inspect the mounts for cracks or separation.
If damaged, replace with OEM or equivalent parts.

3. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and check the fluid level.
If low or contaminated, drain the fluid and replace with manufacturer-recommended transmission fluid.

4. Examine Exhaust System

Raise the vehicle using a jack and secure it with jack stands.
Inspect all hangers, clamps, and connections for looseness or damage.
Tighten any loose components or replace damaged sections.

5. Inspect Drive Shafts and CV Joints

Check the drive shafts for any visible signs of wear or cracks.
Inspect CV joint boots for tears or leaks.
Replace any worn or damaged components as necessary.

6. Test Ignition System

Use a multimeter to check the resistance of spark plugs and coils.
Replace any faulty components with new ones as per manufacturer specifications.
