Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical components, and allow the engine to cool before working on the steering system.

2. Replace Power Steering Fluid

Drain the existing power steering fluid from the reservoir into a catch pan.
Refill with the manufacturer-recommended power steering fluid (refer to the owner’s manual for the correct type).
Run the engine and turn the steering wheel from lock to lock to purge air from the system.

3. Replace Steering Rack (if necessary)

Tools Required: Socket set, wrenches, torque wrench, steering wheel puller, hydraulic jack, jack stands.
Raise the vehicle using a hydraulic jack and secure it on jack stands.
Remove the front wheels to gain access to the steering components.
Disconnect the steering shaft from the steering rack.
Unbolt the steering rack from its mounting points and remove any necessary components (e.g., hoses, brackets) to facilitate removal.
Install the new steering rack by reversing the removal steps and ensure all bolts are torqued to the manufacturer’s specifications.
Reconnect the steering shaft and check for proper alignment of the steering components.

4. Alignment

After completing repairs, perform a wheel alignment to ensure proper handling and tire wear.
