Cure the dreaded with PPE's Transfer Case Pump Upgrade kit.Pump rub occurs when the 5 positioning tabs holding the pump in place wear over time, thus causing the oil pump to come into contact with the housing itself. The result is a hole in the cover, causing fluid to leak and the possibility of heavily damaging the transfer case. PPE's kit consists of a new pump cover whose main feature is a more secure method of mounting the pump. All the necessary gaskets are included.
