1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Remove any covers obstructing access to the engine mounts.
2. Use a socket set to remove the bolts securing the engine mounts to the frame.
3. Lift the engine slightly using an engine hoist or jack to relieve tension on the mounts.
4. Replace the old mounts with new ones, ensuring they are seated correctly.
5. Torque the bolts to the manufacturer’s specifications (refer to the service manual for exact torque values).

3. Inspect and Replace Suspension Components

Sub-steps:
1. Raise the front of the vehicle and secure it on jack stands.
2. Visually inspect the suspension components (control arms, bushings, ball joints) for wear.
3. Replace any damaged components using a socket set and torque to specified values.
4. Align the suspension if necessary after component replacement.

4. Inspect Drive Shaft and U-Joints

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the drive shaft by loosening the U-joint bolts with a socket set.
3. Inspect the U-joints for play or damage; replace if necessary.
4. Reinstall the drive shaft and torque the bolts to the specified values.
