Bye Bye CV Axles
So over this winter, I swapped on Z3 hubs on my stock trail arms and CV axles. And possibly >200KM into the setup, I’ve blown my axles as they’re leaking from both the diff flange and the hub region.
Could any 5 lug experts explain what went wrong and next steps to take ?
I should mention that this car was originally a 320i and i’ve swapped the engine to an M20B25 but retained the 168mm diff and stock axles.
