Just some looking for info on changing out my Power steering pump on my 02' f150 4x4 hopefully before snow flies.:icon_thumby:
Anyway, I think/ pretty sure I need 3A674(STP-86-RM) , but I also see that STP-130RM may work too.... so my question is which is right and what is the difference??? Does it matter?

Well and also, how big of a chore is it to change one out? Getting the drive pulley swapped seems to be one of the top hemorrhoids :shok:

SO 3A674 is a base number, and doesn't tell you much of anything aside from "it's a power steering pump".

I am not sure what the exact differences are between the two parts you posted, but the only thing I can remember is that on some years the pump is held by four bolts, other years it's only three. Shouldn't affect fitment if you use one or the other.

Changing a Triton engine's PS pump is not what I would call fun, but it isn't terrible. The worst part is the pulley. The bolts can usually be accessed pretty easily through the wheel well with long extensions.

hey thanks for the reply. I'll look things over more closely before I start and double check the mounts. I was suspicious it wasn't easy....but doable.

sucess

well about a month ago I did get the PS pump swapped out.

The bigger chore was getting the new high pressure hose to start back into the steering gear box. If I had to do it again I probably would remove the fan and the shroud ....just for a bit more room to work.
