Solution

1. Preparation

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

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Use a socket set to remove any bolts securing the control arms.
- Check for cracks, wear, or excessive play in bushings.
- If damaged, replace with new control arms and bushings, tightening to manufacturer specifications.
Check CV Joints:
- Lift the vehicle and remove the wheel to access the CV joint.
- Inspect the joint and boot for any tears or grease leakage.
- If the boot is torn or the joint is damaged, replace the CV axle.

3. Wheel Bearing Inspection and Replacement

Check Wheel Bearings:
- After lifting the vehicle, grasp the wheel at the 12 and 6 o'clock positions and wiggle it. Any movement indicates a bad bearing.
- If defective, remove the wheel and brake assembly to access the wheel bearing.
- Replace the bearing using a bearing press and ensure proper torque is applied when reinstalling.

4. Power Steering Fluid Check

Inspect and Refill Power Steering Fluid:
- Locate the power steering reservoir and check the fluid level.
- If low, refill with the manufacturer-recommended fluid.
- Check for leaks in the power steering lines and repair any issues found.
