Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Jack and jack stands, socket set, OBD-II scanner, torque wrench, mechanic's stethoscope.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before working underneath.

2. Engine Oil Inspection and Change

Check Oil Level:
- Remove the dipstick, wipe it clean, reinsert, and remove again to check the oil level.
- If low, add the manufacturer-recommended oil type.
Change Oil:
- Drain the old oil using an oil pan.
- Replace the oil filter using an oil filter wrench.
- Refill with fresh oil to the recommended level.

3. Inspect and Replace Engine Mounts

Remove Engine Mounts:
- Locate the engine mounts (usually on the left and right sides of the engine).
- Use a socket set to remove the bolts securing the mounts.
Install New Engine Mounts:
- Position the new mounts in place and hand tighten the bolts.
- Torque to the manufacturer’s specifications.

4. Drive Axle and CV Joint Inspection

Check for Damage:
- Inspect the CV joints and axle boots for tears or grease leakage.
Replace if Necessary:
- If damaged, remove the axle from the transmission and replace it.
- Use the torque wrench to ensure proper tightness on the axle nut upon reinstallation.

5. Exhaust System Check

Visual Inspection:
- Check for loose hangers or damaged parts in the exhaust system.
Tighten or Replace:
- Tighten any loose components. Replace any damaged parts as needed.
