We can help. We have a large inventory of rebuilt NV246 transfer cases plus Transfer Case parts.

NV246 Transfer case replacements and parts

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.
