Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace CV Joints

Tools Required: Jack and jack stands, socket set, torque wrench, grease.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel on the side with the suspected CV joint issue.
Detach the axle nut using a socket wrench.
Disconnect the CV joint from the hub assembly.
Inspect the CV joint for wear or damage; replace if necessary.
Reassemble by reversing the removal steps, ensuring proper torque specifications for the axle nut.

3. Check and Replace Engine/Transmission Mounts

Tools Required: Socket set, torque wrench, pry bar.
Locate the engine and transmission mounts.
Inspect for visible cracks, breaks, or excessive wear.
If damaged, remove the mounting bolts and replace with new mounts.
Tighten new mounts to the manufacturer’s torque specifications.

4. Inspect Suspension Components

Tools Required: Socket set, pry bar.
Visually inspect control arms, bushings, and struts for damage.
Use a pry bar to check for play in bushings and joints.
Replace any worn or damaged components, ensuring all bolts are torqued to specifications.
