Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check fluid level; if low, top off with manufacturer-recommended fluid.
If fluid is discolored or contaminated, drain the fluid using a turkey baster and replace with new fluid.

3. Replace Damaged CV Joints or Axles

Raise the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a socket set.
Inspect the CV boots for tears; replace any damaged CV joints or axles.
- Remove the axle nut using a socket.
- Detach the lower control arm from the knuckle.
- Pull the axle from the transmission side and install the new one.

4. Replace Wheel Bearings

After removing the wheel, unbolt the brake caliper and rotor.
Use a bearing puller to remove the old wheel bearing from the hub.
Install the new wheel bearing using a press or hammer and appropriate adapters.
Reassemble the brake components and wheel.

5. Inspect and Replace Suspension Components

Visually inspect control arms and bushings for cracks or excessive wear.
Replace any damaged components by unbolting them from the chassis and reattaching new parts with a torque wrench set to manufacturer specifications.
