Looks great. Don't know how I missed this thread for so long.
so which part of this is an MJ?
:roflmao:
looks great. can't wait to see where you go with suspension.
The pressure's on!! :lickout:It's slowly coming together, but February seems like it's just around the corner.
Any update?
The reason for the switch is with traditional steering (no full hydro) the steering will be forcing the axle from side to side. We could run a track-bar, but that will induce bump-steer (not good when you're hauling ass through the desert), and more suspension binding. A three link will have no binding, and the track-bar will keep the axle centered.
So a four link with a track bar will bind and have bump steer, but a three link with a track bar will not bind and not have bump steer?
Maybe I haven't had enough coffee yet this morning, but somehow that logic is lost on me....

I still don't see why...I guess I need some 3d animation. :dunce:
I fully understand that, now how is a three link any different? It seems to me that a three link keeps the axle located exactly as a four link, the missing link does allow for more articulation..... But how does that prevent bump steer?
To me it seems that track bar vs the steering is what causes bumpsteer. So how does eliminating an upper link change that if no other changes are made?
a triangulated 4 link will have bumpsteer because the triangulation in the links is going to move the axle pretty much straight up and down, whereas the drag link wants to move in an arc. in order for the axle to cycle, the drag link will turn the knuckles/steering box resulting in bumpsteer.
a trackbar, setup properly, will move the axle on the same arc as the drag link, hence them needing to be parallel and the same length... so the have the same arc.
running both a triangulated 4 link and a panhard creates bind because the 4 link is trying to move the axle in one direction, and the panhard is trying to move it side-side.
eliminating one upper prevents the link geometry from locating the axle, that is left up to the panhard.
one could run a 4 link+ panhard with no bind if the links are parallel and not triangulated.
