Synthetic type F power steering fluid?

Hey guys,

I have been having problems with my power steering gear leaking now that it is cold outside. Everything was fine this summer, but the other day it was 0 out and I had to drive my truck to work. A lot of fluid leaked on that day and now it leaks all of the time no matter the temp out. I did replace all the seals before installing the box so they are about 4 months old.

I thought maybe my junkyard steering gear had moisture in it, so I flushed it out with clean fluid again. No change really.

I’m assuming the seals have been slightly ruined so I have a new set to put in.

The ultimate fix is probably going to be installing a redhead PS gearbox that is machined for bearings and helps hold the main shaft steady.

I’m wondering if anyone has used synthetic type F ATF in their steering gear? Maybe it wouldn’t be so thick in the cold and put less pressure on the seals?

If that pump gas any slop (extra play over factory spec) in the front bushing then the seals won't last very long. Best of luck (y) :nod:
