(long screwdriver) anyone else had this problem? if not ill just wait till something breaks. then ill know what the hell it was! < Message edited by zero psi -- 11/25/2005 9:27:35 PM > _____________________________ 01 jimmy, 95 blazer, 01 sonoma, 75 kawasaki kz400, 87 starcraft popup lol!

I'd check and make sure that the PS res is full. It is possible that the pump is starting to go, but being lubricated by the PS fluid, it doesn't feel bad to the touch. It also wouldn't be a bad idea to change the PS fluid. _____________________________ Kyle- 2004 Rainier 1970 Chevelle - Resto 1974 K5 Blazer - Resto (in reply to zero psi) Post #: 2
