Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Engine/Transmission Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove the bolts securing the engine and transmission mounts.
Use a pry bar to carefully lift the engine/transmission assembly for easier access to the mounts.
Inspect the mounts for cracks, tears, or excessive wear; replace if necessary.
Install new mounts and torque the bolts to manufacturer specifications.

3. Inspect and Replace Suspension Components

Tools Required: Socket set, wrenches, torque wrench, ball joint puller
Remove the wheel to gain access to the suspension.
Inspect the struts, shocks, and control arms for wear; replace any damaged components.
If necessary, use a ball joint puller to remove and replace any worn ball joints.
Reassemble everything and torque components to the manufacturer's specifications.

4. Inspect and Replace Wheel Bearings

Tools Required: Socket set, torque wrench, bearing puller
Check for play in the wheel bearings by rocking the wheel back and forth.
If play is detected, remove the wheel hub and replace the bearings.
Reassemble the wheel hub and torque the retaining nut to specifications.
