Update: I finally got around to installing a different lower control arm and fulcrum pin. Everything went on as it should. I tighten up the fulcrum pin and The dog bone had the same movement as the other side so I would consider this a successful fix! I’ll try to add pictures once I figure it out. I would like to thank everyone for your help, greatly appreciated and keep up the good work guys! Mklotz, I think it would be great if you continue making parts for these trucks. Some of us can definitely use them.

I think I found the problem, seems that the inner threads of the lower control arm to where the fulcrum bushings screw onto are stripped. Causing the bushings to move w/the control arm when they are tight and I move it with force. I’m going to see if I can find a spare one local to me...sux.

Thanks Mklotz, I watched that video several times prior to the reinstall very useful, by the way. I’ll go ahead and start moving things around and hope I figure it out this puzzle. I need to get this rig back on the road. Thanks for responding greatly appreciated.

Hi everyone, first time post. I don’t ask for help unless I exhausted all of my options and haven’t drank enough beer. I just got my king pins done on my 72 521. I started to reassemble things back together and the driver side spindle gets super hard to move when I torque down the fulcrum bushings to 80-90 lbs. The passenger side is fine. I tried swapping bushings thinking it was the issue, but nope. Another thing that’s really got me confused is I torque bushings to 90lbs. and the right side bushing on the fulcrum rotates with the spindle when I move it around. This is my first Datsun so Any help would be greatly appreciated. I did search, but found no solution. She’s my daily and I need to get her back in the road, thanks in advance.
