1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, jack stands, impact wrench, pry bar.
Raise the vehicle and secure it on jack stands.
Inspect the struts and shocks for leakage; replace if necessary.
- Remove the strut assembly bolts using the socket set.
- Replace the strut or shock, reinstall and torque to manufacturer specifications.
Check control arms and bushings for wear.
- If the bushings are damaged, replace them by removing the control arm bolts and pressing out the old bushings.

3. Check and Replace Engine/Transmission Mounts

Tools Required: Ratchet set, torque wrench.
Locate the engine and transmission mounts.
Inspect for cracks or excessive movement.
If replacement is necessary:
- Remove the bolts securing the mount to the frame and engine/transmission.
- Install the new mount and torque to specifications.

4. Inspect and Replace Drivetrain Components
