Rear bearings, green vs timken

Green bearings get a bad rap because there are two kinds. The first older style was an inferior design and was prone to failure due to excessive side loading. The second later designed is much improved having resolved those issues.

I used to know how to tell them apart by number and name, but I have forgotten. Maybe Supershafts or Dr Diff will chime in. I have seen one or the other....or maybe both talking about the same thing.

The green style bearings have been used on cars and trucks for a very long time and you do not see large scale failures. It's a very good design, you just have to get the right ones.
