Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery if working with electrical components.

2. Inspect and Replace Engine Mounts

Sub-steps:
- Lift the vehicle using a jack and support it with jack stands.
- Remove any obstructions to access the engine mounts.
- Visually inspect the mounts for cracks or excessive wear.
- If damaged, use a socket set to remove the bolts securing the mounts.
- Replace with new engine mounts and torque bolts to manufacturer specifications (refer to service manual for torque values).

3. Wheel and Tire Inspection

Sub-steps:
- Remove the wheels using a lug wrench.
- Inspect tires for uneven wear, bulges, or damage.
- Check wheel balance using a tire balancing machine.
- Reinstall wheels and torque the lug nuts to the proper specifications.

4. Drive Axle and CV Joint Assessment

Sub-steps:
- Examine the CV joints for any signs of grease leakage or damage.
- If damaged, remove the axle using a socket set and replace with a new or reconditioned part.
- Reassemble and ensure the axle is properly seated in the transmission.

5. Exhaust System Check

Sub-steps:
- Inspect the exhaust system for loose or damaged hangers.
- Tighten or replace any loose components to prevent contact with the chassis.
