Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level; if low, top off with manufacturer-recommended fluid.
If fluid is dark or contaminated, drain and replace the fluid.
Reconnect the battery and turn on the vehicle, then turn the steering wheel from lock to lock to bleed air from the system.

3. CV Joint and Boot Inspection

Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a socket set.
Inspect the CV joints for any visible grease leaks or damage.
If damaged, replace the CV axle.
- Sub-steps for Replacement:
  - Remove the axle nut and disconnect the axle from the hub.
  - Remove the inner joint from the transmission.
  - Install the new CV axle in reverse order, ensuring the axle nut is torqued to manufacturer specifications (typically around 150 ft-lbs).

4. Wheel Bearing Inspection and Replacement

Spin the wheel while it is off the ground to check for any grinding noise.
If noise is present, remove the wheel hub assembly.
- Sub-steps for Replacement:
  - Remove the brake caliper and rotor.
  - Disconnect the hub from the steering knuckle and replace the wheel bearing.
  - Reassemble the hub, ensuring all bolts are torqued to specification.

5. Suspension Component Inspection

Check control arms, bushings, and struts for any signs of wear or damage.
Replace any worn components following the manufacturer's torque specifications.
