[Oletrucks] Power steering rack

[boedigheimer]

I am at the end of my rope on this one. In building my 1949 GMC I took a 
79 Chev 3/4 ton front end and narrowed several inches out of the middle. 
It mounted well and looks like cast , camber , toe, and bump steer will 
be acceptable. Of course I cant use the original drag link and tie rods 
since it is narrow so I got a rebuilt steering rack from a 1998 Dodge 
Dakota thinking the same width, should be easy to mount. I got it fit up 
and working and all was well until I hit the steering stop. The left 
seal blew on the rack and leaks oil. Tryed another rack same issue. 
Turned the steering pump relief valve down to about 700 psi and thought 
I had it this time but no, when it hits the stop on a right turn, the 
seal began blowing oil out the left side of the rack. there is no 
binding or such and the system can be turned by hand with the engine 
off. I don't understand why it would blow the seal consistently.
I am hoping for some ideas from you all or suggestions of issues I may 
have overlooked, or options instead of the Dakota rack...

Thank you
