Dylan Berichon Posted March 25, 2015 Report Share Posted March 25, 2015 Hi All! I'm wrenching on my 1980 720 Longbed. Been busy replacing the front end suspension and steering components this past week, but have hit a couple of snags. It appears that there is a major issue... somewhere. I'm wondering if the upper control arms might be bent, or if the subframe is messed up somehow. Here's some photos of the passenger side. It appears someone replaced the upper control arm at some point with a unit out of a junk yard: The arm is making contact with the shock, even when the car is sitting on the groud. The old shock I had pulled off was actually bent. The tire also sits at the wrong angle, there's a LOT of negative camber (tire points towards the middle of the truck). It's as though the upper control arm is too short. Also, when trying to get the control arm off the drivers side of the car, I wasn't able to get the upper control arm to clear the inner part of the fender. I disconnected the ball joint, and the two bolts on the back of the arm (just like the manual says to do) but I couldn't get the right angle to get the arm off. Photo of the drivers side: Any ideas how to proceed from here? I'm not sure how to fix these issues. And finally, does anyone know where I can source new upper control arms for this thing? I've scoured and haven't been able to find them anywhere. Thanks as always! Quote Link to comment
ggzilla Posted March 25, 2015 Report Share Posted March 25, 2015 720 doesn't have a subframe, it has a full frame. Looks like the wrong part is installed. Maybe the UCA is from a 620 Quote Link to comment
datzenmike Posted March 27, 2015 Report Share Posted March 27, 2015 Has the truck been raised? Right arm on the left side? How about a picture of the right side to compare? Quote Link to comment
Dylan Berichon Posted April 7, 2015 Author Report Share Posted April 7, 2015 Thanks to the folks at the local alignment shop, I've found out that the truck has a bent frame. This explains a great deal. I wonder how easy / difficult it would be to straighten it out. Quote Link to comment
