1. Preparation

Gather necessary tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues while working.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top off with the manufacturer-recommended fluid.
If the fluid is dirty or contaminated, drain the system and replace with new fluid.

- Lift the vehicle using a jack and secure it with jack stands.
- Remove the front wheels.
- Use a socket set to remove the nuts and bolts securing the damaged component.
- Install the new component and torque to the manufacturer specifications.
- Reinstall the wheels and lower the vehicle.

4. Inspect and Replace Wheel Bearings

If wheel bearings are found to be faulty:
- Remove the wheel and brake assembly.
- Use a bearing puller to extract the old wheel bearing.
- Install new wheel bearings, ensuring proper alignment and lubrication.
- Reassemble the brake assembly and wheel, torquing to specifications.

5. Check and Replace CV Joints if Necessary

If CV joints are damaged:
- Remove the axle from the transmission side.
- Inspect the joints for wear or damage.
- If needed, remove the boot clamps and replace the joint by following the manufacturer’s procedure.
- Reinstall the axle and torque all fasteners correctly.
