If you have the version that's mounted using just two cover bolts - I can imagine that being a potential problem. If you have the version where you have an additional screw on the diff cover - that might be better, provided that the mentioned screw doesn't go to ****.

I think that altogether - it's a bad solution and you should change bushings.
