Help with A arm shaft end bolts/bushings - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have disassembled my front suspension on my 70 1/2 ton 2WD and had all parts powder coated. I'm ready to reassemble and I'm wondering how tight the end bolts on the A Arm shafts need to be. They were very difficult to get appart. I have purchased a rebuild kit from PST and I don't know how to tell when they are in far enough. Is there a torque spec? Any and all advice will be greatly appreciated.

I don't have the torque specs at work, but as I remember because of the way they are made they will stop turning as the flange will hit the a-arm. I tightened mine that far.

Check the Haynes manual. They're in the beginning of the chapter on suspension for 1/2 ton trucks.

I think they where something like 90 ft-lbs, but I can't remember. I just torqued em down till they didn't move any more since I didnt have a socket big enough.
