Posted October 27, 20159 yr So I made a small scale solid axle just for fun and I think it turned out quite well, but it wiggles side to side a bit too much. Here are some pictures. Any thoughts would be greatly appreciated. Those are the pictures of the axle, now here is the problem. The above two pictures show the extent of the wobble.
October 27, 20159 yr Most vehicles with solid axles have a third link to center the axle, just look at the instructions for 8110 and 42043 to see what I mean.

The problem with that is that if I attach it in a way that allows each wheel to flex independently, it will not stop it from wiggling. Is there a way to retain independence while removing wiggle?
October 27, 20159 yr Put a third like directly over the U joint and 6L links and link it above the end of the 6L links on the axle. Should work

October 28, 20159 yr What you need is a panhard rod: https://en.m.wikiped...iki/Panhard_rod There are other solutions, like triangulated suspension links, but they are probably too big here. Edited October 28, 20159 yr by John Daniels

Sorry here is a picture I found of what I am taking about The very right axle has the third link like I was talking about. It connects to the chassis and it allows no side to side but allows flex.

October 28, 20159 yr instead of the ball joints and steering arms use half pins and these ... Should still get the flex but perhaps a bit too stiff - so experiment with full pins or halfpins on the chassis and full on the axle etc...

I don't see how that would work, because when it flexes the entire axle is rotated, so a liftarm would not connect.
October 28, 20159 yr yes it will restrict the axle flex - but try it it may allow just enough if you use full pins all sides or use the steering arm on pins ir axles instead of ball joints (as seen on sheepo's MAP chassis)
October 29, 20159 yr Author Thanks a billion for all the great suggestions everyone. I have ended up using a panhard rod, because I couldn't get anything else to work well. Hopefully soon I will be posting a topic about this truck.
