Do you think there is any way you could have rebuilt it, from a parts perspective?

Aside from drilling it and using a removal tool I'm not sure what can be done about the subframe bolt. That sucks.

If I had a spare pinion gear and crown gear, with the front/rear pinion bearings, along with the centre crush ring for the pinion, yeah it could be rebuilt. I assume there are specialty tools needed though, it looks like the pinion is pressed in and there isn’t an easy way to get it out. The damage on the centre bearing housing wouldn’t influence the usability and it seems the axle gears and floating gears are fine.
It’s just a matter of getting all the parts and tools needed, I looked and cannot easily get them to me with shipping/cost etc.

Any ideas if it would be a good idea to drive the x5 without that subframe bolt? I’m assuming it’s a dreadful idea but at the moment it’s our only car :/

Thanks!!
