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.

Dogs would not even put in their mouth!
Flavor Name: Beef, Size: Large
Toy is rock hard. Have seen toys like that before, but the smell is disgusting. I have 5 dogs, and while this was purchased for one in particular, none of the dogs would chew on it. Only one put it in his mouth, and then immediately spit it out. My dogs are not picky or finicky but none would have anything to do with it. Total waste of money.

8 months later, my dog's favorite toy by far!
Color: Ring, Color: Ring
My dog has a LOT of toys, and this is her favorite. We've had it for 8 months and it still holds up. She likes to pull at the stitching (and has removed a bunch), but the toy still holds together surprisingly well. It's a great value for the money.

Not good for aggressive chewers
Color: Ring, Color: Ring
My aggressive chewer had pieces of leather and felt chewed off within 10 minutes. Had to take it away from him because I didn’t want him swallowing them.
