So i had searched high and low through BeamNG website which i seem to have difficulty doing with the search function and how it's set up and the results i did get were not what i was looking for. I was looking for a mod that would let you have a rwd transfer case for the covet instead of fwd and haven't had any success. At one point someone had made a mod that enabled all vehicles to have multiple transfer case configurations for fwd, rwd or both and i no longer have it. For if i remember correctly it was outdated and caused my game to crash or when i kept having issues where i had to delete all local content in my mods folder. Since then or recently i haven't been able to find it or something similar. Does anyone know where i can find that mod or something similar and perhaps with a link?
I'm fairly sure this one by @Justy4WDTURBO is updated and working, you can find it here: https://www.beamng.com/threads/covet-4wd-cvt.32605/#post-474845
If it's still using the bits I threw together that one time then yeah you can remove the front diff while using the selectable 4wd gearbox, put it into 4wd and because the center is locked it should send power to the rear axle just fine
