Hi guys,
I was wondering what oil you guys run in your 5,000 Ford rear differential? I have a 600 Ford then I have ran 80w 90 gear oil for 20 years and it has work flawless. But it does have a piston pump whereas the 5,000 has a Gear Drive pump. When I rebuilt it I put 68 Universal hydraulic oil in it. My pump is making a lot of noise I read somewhere that the wrong oil would cause that. Just want to know what you guys run.
Thanks
DAN
