Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint puller, grease.
Remove the wheel on the affected side to access the CV joint.
Using a socket set, remove the axle nut and detach the CV joint from the hub.
Inspect the CV joint for torn boots or excessive play. If damaged:
- Use a CV joint puller to remove the joint from the axle.
- Clean the axle and apply new grease.
- Install a new CV joint and reattach it to the hub. Torque the axle nut to the manufacturer’s specification.

3. Inspect and Replace Engine/Transmission Mounts

Tools Required: Socket set, torque wrench, jack and jack stands.
Locate the engine and transmission mounts.
Use a jack to support the engine/transmission.
Remove the bolts securing the mounts using a socket set.
Inspect the mounts for cracks or separation. Replace if necessary:
- Position the new mount and torque bolts to manufacturer specifications.

4. Check Suspension Components

Tools Required: Socket set, torque wrench, pry bar.
Inspect struts, bushings, and other suspension components for wear.
Replace any worn components:
- Remove the affected parts using a socket set and replace with new parts.
- Ensure all components are tightened to specified torque values.
