Merchant Transfer Case Pump Upgrade
The GM transfer case use a gear pump inside the case that is driven off the mainshaft. This pump forces oil to the planetary as well as the drive sprocket sleeve. The 5 tabs around the housing fit into the spots in the rear housing are what positions the pump. Over time, the pump can start to wear on the rear housing. This is commonly referred to as pump rub. Each transfer case includes the Merchant Automotive Pump Upgrade to alleviate these "Pump Rub" issues.

Me gusta
Me gustó que no tiene mucho aroma ya que soy alérgica a los olores fuertes. Pero no brillo tanto como quería. Lo bueno fue que no mancho mi prenda de vestir

AMAZING. Last a long time. Super glittery. It does feel a little sticky when you first spray it on but once it gets down you can't even feel it.
