Eliminate the joint at center of the link. Weld the tubes together. A radius arm doesn't pivot in the middle.Well finally an update...
I had to gather the motivation to replace the tranny for the 3rd time in 500 miles, but I did get it installed and actually wheeled.
Everything flexes well and is stable but I do need to figure out how to stop the links from rotating, and changing lots of angles.
Here is the right side.
and the left side
I'm thinking about a couple of options, weld a DOM bushing at the axle end of the lower link, and another is invert the links, putting the long link from the frame end to the upper hole on the axle and make the short link connect to the lower axle mount.
I think I might plate one side, the passenger side and do nothing with the drivers side and see what happens.
Sure, at the time if the initial design, I don't see how I would have been able to place the upper link on a truss over the diff and clear the oil pan with the ride height I was expecting.Any particular reason you didn't go with a 3 link?
Buck:I'm not too sure I would be comfortable driving the 3 link I'd have to build, on the road, at speed, and being able to drive to the trails was just about my #1 requirement for this rig.
I think my front 3 link issues are running my upper link(s) off of my lower links and the rotation of the links I could not control with this design. If I had the frame end of the upper link on the frame, I don't think the axle would be able to rotate, even if the upper link was paralell to the lower link (instead of angled in to the top of the diff).Buck:
I’ve read both of your link builds and also read 472Scout’s. It appears you did a lot of research so maybe you ran across some 3 link issues you did not mention. What made you uncomfortable about driving a 3 link? Fabrication skills and relying on one link or the way it functions? If function, what?
I’m in the layout phase of linking my 80 and do not see a way to get the upper (third) link to the middle of the axle due to obstructions. I’ve read that attaching the single upper link offset to one side will cause the Scout to pull to the opposite side of the Scout the link is on during braking. I can see how this would happen and am curious if you ran across the same issue.
If anyone else has experienced this please share.
Also, how close do the top of your front tires get to your coilovers on the front during articulation?
