Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and securely raised using jack stands if necessary.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Power Steering Fluid

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

3. Inspect and Replace Steering Rack

Remove the steering column cover to access the steering rack.
Disconnect the power steering lines using a socket set.
Remove the mounting bolts securing the steering rack to the chassis.
Carefully slide the steering rack out and replace it with a new or reconditioned unit.
Reinstall the mounting bolts and reconnect the power steering lines.

4. Inspect and Replace Wheel Bearings (if necessary)

Lift the vehicle and remove the front wheels.
Remove the brake caliper and rotor.
Use a socket set to remove the axle nut and any retaining bolts for the wheel hub.
Carefully pull the wheel hub assembly off and inspect the bearings.
Replace the bearings if they are damaged, using a press if necessary to install new ones.

5. Inspect and Replace CV Joints (if necessary)

If CV joints are suspected, remove the axle from the transmission side.
Inspect the boots for tears and the joints for wear.
Replace any damaged CV joint assemblies.
