Pitman Arm problems

Pitman Arm problems

Postby gcalledinsick [OP] » Dec 04 2011, 11:51pm

i got an aftermarket pitman arm that wont seat on stearing box. the aftermarket replacement looks like the same dimensions and same tooth count and even calipered the diameter and its the same but it still wont seat all the way. when i turn lock to lock i cant turn fully to the right b/c the tie rod hits the frame. the only difference i notice between the old and new is the joint end is much larger on the old arm.

so is it possible the steering box was swapped with another model or maybe the aftermarket parts do not fit the same way? any help would be greatly appreciated. thanks

As far as it not seating all the way, that is not uncommon, because the replacement arm may start it's taper at a different diameter. Just make sure you can get it tightened down to the correct torque. Make sure it doesnt bottom out on the box (as if the hole was too big, and didn't allow for a good press fit). As far as the tie rod hitting the frame, have you added a lift kit? I don't see a reason (by the pictures of the arms) that you should be having geometry issues.

Kinda sounds like its not "centered" correctly,dont the arms have 1 spline that is larger than the rest and if that spline is not where its supposed to be the arm would not seat and would throw off the "turn to stop" ratio. Just my $.02 :P

I put one on a GMC Sierra last night. They had two different ones to choose from (you had to know what kind your truck had). Apparantly GM made some with 3 master splines and some with 4 master splines. I'm not sure if a 3 master spline pitman arm will fit on a 4 master spline steering box, but a 4 master spline pitman arm will not go on a 3 master spline steering box.

oh ya, thanks for the help. it ended up being the idler arm. it was bent up instead of down. just the wrong part. the pitman arm was fine i guess its not meant to seat all the way like the oem one.
