bar setup rose joint both ends of the ladder bar.
A standard gem diff assembly moves straight up & down,
same as a 4 link. Hence why the end of the torque tube
mount is rubber, so it can move telescopicly (moves
forwards & backwards).
If you have a rigid mounted ladder bar it trys to move
the diff in an arch & because the mounting point(pivot)
is different to the trailing arm mounts. It will
'bind up' when going through it's travel path.
On my setup I copied an end of a nissan patrol radius
arm on the lathe & welded it to the end of the ladder
bar. Rubber mounted & performs exactly the same
as a patrol arm. This way the ladder bar can still move telescopicly
according to the position of the diff. The mounting point
I made as close to the lower arm mounting points as
possible. The same length but 5mm higher.
A 4 link would be soooo much easier!
