Power steering pump whining.

Unread post by East Coast Traveller » March 29th, 2015, 1:00 pm

Hi All.
I fitted new Crown power steering pump to my 2002 4.7 V8 Grand Cherokee limited as the previous pump leaked. Six thousand K's later I have a quite loud whine from the pump. My supplier can not supply a replacement Crown at the moment, so has sent a second hand genuine pump, it whines too, but nowhere near as loudly. Anyone else have this problem? Could it be the oil?

Is the fluid reservoir full? Power steering pumps develop a noticeable whine if the fluid level drops significantly.

is it really the pump? the aircon pump pulley bearing can make a similar noise, as can the idler pulleys.

Thank you gentlemen, I will check the fluid level as well as the idler and aircon pulleys.
