1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery before starting any work to ensure safety.

2. Inspect and Tighten Components

Tools Required: Socket set, torque wrench, and pry bar
Inspect all visible mounting bolts on the exhaust system, driveshaft, and suspension components.
Use a torque wrench to tighten any loose bolts to manufacturer specifications.
Check for missing bolts and replace as necessary.

3. Replace Damaged CV Joints

Tools Required: Socket set, CV joint puller, grease, and new CV joint boots
Raise the vehicle securely on jack stands.
Remove the wheel to access the CV joint.
Unbolt the CV joint from the wheel hub and the transmission.
Replace the CV joint with a new one, ensuring proper alignment and secure mounting.
Reinstall the wheel and lower the vehicle.

4. Replace Engine and Transmission Mounts

Tools Required: Socket set, torque wrench, and possibly an engine hoist
Identify the engine and transmission mounts by locating the mounting points.
