The rear drive shaft carrier bearings on an ST185 had this as the original Toyota P/N:
- 37230-20120: Bearing Assy, Center Support, No.1: Qty. Req'd: 2
In North America, this bearing was also used on the ST165. Same is true in Europe, Japan, and other markets.
P/N 37230-20120 was superseded by 37230-20121.
From what I can see, neither P/N is available from Toyota anymore.
I was in the Febest catalog - I could not find a Febest alternative to this bearing. Perhaps they made them at one time, but I can't find any current inventory.
