Hello, I've been building with lego technic for a couple of years, but found myself never having the right pieces for my builds. I recently bought a second-hand lego set with some nice wheels (8386). So I could finally start building some bigger and cooler cars. I started with my first supercar this week and am having trouble with the rear axle. I am using the method you see in this picture (https://ibb.co/ciYnN5) with 2 separate axles. The problem is that I want to use a differential, but can't figure out how that would work with this. Does anyone have a solution for this, or does anyone have a different, stable (compact) method for this? Any rear axle that has suspension is welcome. I would appreciate it to see more ideas from you. One more thing to keep in mind is that I only have the type of universal joints you see in the picture (https://ibb.co/ciYnN5). I don't have any other. Thanks in advance ;)
