Not sure what the factory suggests, but i do it about every 30,000 miles. Its not hard nor expensive to do.
X2I do it every year. same with trans fluid. cant hurt.
Yep dex 3 gets chewed up pretty quick in there. 30K is the interval I use.X2
I'm surprised by how quick the ATF gets dirty.
That's a good idea, I might have to try that.I would go buy a set of star bits (torx) and find the one that's closest and POUND it in so it fits good and snug.
Ask him and let us know.Why would my dealer change the transfer case fluid twice in one day?
