This is the front case half for the Borg Warner 4405 transfer case. The oil pump stabilizer wears into the side of the case and the shift rail wears it's bore as well. When this happens the shift fork can disengage the shift cam and the transfer case fall out of gear. The first indication you will get is a whirring noise when you let off the gas. We have these case halves in stock.

The core charge for the case halves will be refunded when the case is returned to us in rebuildable condition.
