Having issues diagnosing problems with your NV246 transfer case?

We have a large inventory of rebuilt NV246 transfer cases plus Transfer Case parts. Our factory rebuilt re-manufactured Transfer Cases are dyno tested before leaving the factory, New Venture Gear for the General Motors and Chevrolet, this transfer case is also sometimes referred to as a NP246.

The NV246 has a factory engineering defect. The oil circulation pump can wear a hole in the rear case causing loss of lubrication fluid and premature transfer case failure. If you just replace the case this will not solve the problem. The NV246 rear case is manufactured using magnesium, it’s soft; the aluminum pumps are harder. We have designed a machined metal protection plate to fix this defect, before this problem arises you should install our Case Saver part number MW52007. A better option is to replace your rear case with the new improved upgraded case shown above. You need to install this part before the oil pump causes your transfer case to fail.
