Replace any damaged hoses using a socket set.
Check the power steering pump for leaks; if defective, replace the pump.

4. Inspect Electric Power Steering Motor

Locate the EPS motor, usually mounted near the steering column.
Disconnect the electrical connector and check for corrosion or damage.
If necessary, replace the EPS motor.

5. Replace Steering Rack and Pinion (if necessary)

Remove the front wheels to access the steering components.
Disconnect the steering column from the rack.
Remove the mounting bolts securing the steering rack.
