I have been working on the axles and the suspension. The original LTM 1055 S4 had the old fashioned Liebherr suspension with coil springs. Only later they introduced the hydraulic suspension.
The third axle also has the transfer box incorporated.
I made most of the parts for the axles, but I first wanted to get the suspension done before finishing them. It is quite tight and needs a bit of figuring to make it all work.
