Are 4x4s broken right now

Every car I export now that has 4x4 selected break as soon as I try to drive them in beamng. For some cars as soon as I lock the differential or change it from 2wd to 4wd the wheels break off immediately citing that the half shafts have broken. Some cars can make it a little further but overall break eventually. I’m sorry if this is a dumb question but I’ve been away from the game for a few months and all these bugs are new to me.

After some testing I’ve found changing the suspension fixes the issue I haven’t test every suspension type but for sure leaf spring is broken when using the 4x4 drivetrain when exported to beamng

Edit 2: figured out it was just a specific mod body that breaks in Beamng. For reference it’s the Brass Era body pack. For some reason it doesn’t export right into beamng and the axles all break
