1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Engine/Transmission Mounts

Inspect Mounts
- Visually inspect engine and transmission mounts for cracks or wear.
- Use a pry bar to check for excessive movement in the mounts.
Replace Mounts (if necessary)
1. Remove any covers or components obstructing access to the mounts.
2. Use a jack to support the engine or transmission.
3. Unbolt the old mounts from the engine and frame using a socket set.
4. Install new mounts, ensuring they are aligned correctly.
5. Torque bolts to manufacturer specifications (refer to repair manual for specific torque values).

3. Tire Inspection and Replacement

Inspect Tires
- Check for uneven wear, bulges, or punctures.
- Measure tire pressure and adjust to recommended levels.
Replace Tires (if necessary)
1. Jack up the vehicle and remove the wheel lug nuts.
2. Remove and replace the tire with a new or properly balanced tire.
3. Reinstall the lug nuts and torque them to the recommended specifications.

4. Driveshaft and Axle Inspection

Inspect Driveshaft and Axles
- Check for any visible damage or wear on the driveshaft and axle components.
- Look for any signs of fluid leaks from the CV joints.
Replace Components (if necessary)
1. Remove the driveshaft or axle using a socket set.
2. Install new components, ensuring proper alignment and securing bolts to manufacturer torque specifications.

5. Suspension Component Inspection

Inspect Suspension
- Check struts, shocks, and bushings for signs of wear or leaks.
Replace Components (if necessary)
1. Remove the damaged components using a socket set and appropriate tools.
2. Install new suspension components, torquing bolts to manufacturer specifications.
