Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Components

Check Power Steering Fluid:
- Locate the power steering reservoir.

- Torque the new pump to manufacturer specifications.

3. CV Joint and Axle Inspection

Remove Wheel:
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the lug nuts and take off the wheel.
Inspect CV Joint:
- Examine the CV joint for tears in the rubber boot or signs of grease leakage.
- If damaged, remove the axle by disconnecting it from the hub assembly and replacing it with a new one.

4. Suspension Component Replacement

Inspect Suspension:
- Check control arms, bushings, and struts for wear.
- Replace any damaged components as needed.
Reassemble Suspension:
- Tighten bolts to manufacturer specifications using a torque wrench.

5. Wheel Bearing Replacement (if necessary)

Remove Hub Assembly:
- Disconnect brake caliper and rotor.
- Remove the hub assembly from the vehicle.
Replace Wheel Bearing:
