Can anybody tell me what changesr are required to install the steering mechanism from a 2003 Prius on a 2001 Prius? The power steering on my 2001 Prius has quit. I can drive the car okay, but I would like to have the power steering back and want to use parts from a 2003 to get the fix made for 2001 and 2002 power steering problems. I have had no respones to this query. Does that mean that nobody knows the answer? Am I the only person with PS failure?
