Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect Power Steering System

Tools Required: Fluid syringe, funnel, rag.
Check the power steering fluid level using the dipstick.
If low, add the appropriate type of power steering fluid (refer to the owner’s manual).
Inspect the fluid for contamination; if dirty, consider a fluid change.

3. Replace Damaged Components

Tools Required: Socket set, torque wrench, jack stands, wheel chocks.
Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the suspension and steering components.

a. Steering Rack and Tie Rods

Inspect the steering rack for leaks or damage.
If damaged, disconnect the tie rods from the steering rack.
Remove the bolts securing the steering rack and replace it with a new unit, ensuring it’s properly aligned and torqued to specifications.

b. CV Joints

Check the CV joints for wear; if cracked, replace the entire axle assembly.
Remove the axle nut and disconnect the axle from the hub, then replace the axle.

c. Wheel Bearings

Inspect the wheel bearings; if they feel loose or are making noise, replace them.
Remove the brake caliper and rotor to access the wheel bearing.
Use a bearing puller to remove the old bearing and press in a new bearing.

4. Reassemble and Lower the Vehicle

Reattach the wheels and lower the vehicle back to the ground.
Reconnect the battery.
