My car's power steering assist fails when i rev over 4,000 RPMs.

Sometimes it returns quickly and sometimes i will come back to my car later and will still be difficult to turn the steering wheel.

What part(s) should i check that can possibly be the culprit ?

Good morning,

This could be the drive belt slipping when the RPM is high. At that point, the tensioner is not keeping the belt tight.

I attached the instructions for the belt and the tensioner.
