Independent of the tools mentioned above, this youtuber was very clever when he replaced the rear bearing on his BMW 3-series...
This youtube video is a must see!

I will highlight a few things:
1. Removing the hub using a bearing separator as a backing device, once the lug bolts are tightened, the hub comes out.
Alternatively, you can place some ? 2x4 wood and a wrench as backing material so the lug exerts the force on the wrench rather than the wood, just a thought...
2. PVC Coupler is no match, it broke...So don't use PVC Coupler.
3. No need for large receiver cup, a few pieces of 2x4 wood and piece of metal (from the internal spring compressor), and the bearing came out!
4. To install new bearing, he used the plumbing disc, but he should have used the OLD bearing as an adapter, just an option.
Here are the photos from the same youtube video...
