Hopefully someone can point me in the right direction. I replaced a 3 year old Red Head box that had developed slop with a new one and went ahead and swapped out to a Borgeson shaft. Ran through the recommended fill and bleed procedure. No slop in the wheel now, but the steering wheel is harder to turn that it used to be by a fair amount and it has no return to center. I suspect that my old pump is blowing by and not supplying enough pressure to help the gear box turn as easily as before? Any advice would be greatly appreciated.
