I got my lift installed and I am trying to install the new pitman arm however it will only go on the vector shaft half way and then sieze. If I use a socket and try to hammer it farther it won't go. So I got the old one and it does the same damn thing. I cleaned the splines on the vector shaft and it still does it. I tried using the nut to get it higher but I ended up stripping the nut.

Any suggestions on how the hell to get this thing on?

I hate to ask this, but did you have it on the right direction? It is cone shaped to fit the shaft, it is possible you just need to flip it over.

naa thanks for the tip though. the problem was that was all the farther it went. there was like 1/2 inch of splines left and the old one fit snug and I thought so did this one but I was wrong.
