Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Check the fluid level against the dipstick or indicator.
3. If low, top up with the manufacturer-recommended power steering fluid.
4. If fluid is dirty or contaminated, drain and replace it by disconnecting the return line.

Tools Required: Funnel, container for draining fluid

3. Replace CV Joints if Damaged

Sub-steps:
1. Safely lift the vehicle and secure it on jack stands.
2. Remove the wheel to access the CV axle.
3. Inspect the CV joint for tears in the boot or excessive play.
4. If damaged, remove the axle nut and unclip the CV joint from the hub.
5. Install the new CV joint by reversing the removal process, ensuring proper torque on the axle nut.

Tools Required: Socket set, torque wrench

4. Replace Worn Wheel Bearings

Sub-steps:
1. Remove the wheel and brake components for access to the wheel bearing.
2. Use a bearing puller to remove the old bearing from the hub.
3. Clean the bearing seat and press in the new bearing, ensuring it is seated properly.
4. Reassemble the brake components and wheel, then torque all bolts to specification.

Tools Required: Bearing puller, press, torque wrench

5. Inspect and Replace Suspension Components as Necessary

Sub-steps:
1. Check for any damaged control arms or bushings by visually inspecting and feeling for play.
2. If any components are worn, unbolt and replace with new parts.
3. Reassemble all connections and torque to manufacturer's specifications.
