Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar
Park the car on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues while working on the vehicle.

2. Inspect and Replace Suspension Components

Inspect Control Arms:
- Use a pry bar to test the control arm bushings for excessive movement.
- If damaged, proceed to replace the control arms.
Replace Control Arms:
- Remove the wheel using a socket set.
- Unbolt the control arm from the chassis and knuckle.
- Install the new control arm, ensuring proper alignment.
- Torque the bolts to manufacturer specifications (check factory service manual for exact torque values).

3. Check and Replace CV Joints

Inspect CV Joints:
- Examine the rubber boots for tears or grease leakage.
- Rotate the wheel to check for play in the CV joint.
Replace CV Joint if Necessary:
- Remove the axle nut using a socket.
- Disconnect the lower ball joint to free the CV axle.
- Pull the axle out of the transmission and replace with a new CV joint or axle assembly.
- Reassemble in the reverse order and torque all fasteners to specifications.

4. Inspect and Replace Wheel Bearings

Check Wheel Bearings:
- Spin the hub to check for roughness or noise.
- If defective, replace the wheel bearing assembly.
Replace Wheel Bearing:
- Remove the wheel and brake assembly.
- Unbolt the bearing from the knuckle and replace it with a new one, ensuring proper alignment.
