Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, stethoscope, torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace CV Joints (if damaged)

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the CV joint boots for tears or leaks; if damaged, proceed to replacement.
4. Disconnect the axle from the wheel hub and remove the CV joint from the transmission side.
5. Install the new CV joint by reversing the removal steps. Ensure to torque the axle nut to manufacturer specifications (typically around 35-50 ft-lbs).

3. Check and Replace Wheel Bearings (if necessary)

Sub-steps:
1. With the wheel removed, grab the hub and check for any play or grinding noise.
2. If play is detected, remove the brake assembly and hub to access the wheel bearing.
3. Use a bearing puller to remove the old bearing and install the new one.
4. Reassemble the hub and brake assembly, ensuring all bolts are torqued to specifications.

4. Inspect and Replace Suspension Components (if required)

Sub-steps:
1. Visually inspect control arms, bushings, and struts for wear or damage.
2. If any components are worn, remove the affected parts using a socket set.
3. Install the new parts, ensuring proper alignment and torque specifications are followed.
