I regularly service my vehicle per the owners manual at the dealership. I have been going through my service records and the manual's suggested maintenance schedule and can't seem to see what is recommended, if anything, for regular maintenance of the 4x4 system. Can someone please let me know what should be done and at what intervals?

 

The only thing in the manual is to change the transfer case fluid at 150k or 60k for severe duty.

 

I'd do mag hytec front and rear covers. That way you don't have to peel off old cover and re gasket everytime.

 

Would take a hell of a lot of fluid changes to make up for the $500 cost for a couple of diff covers ...

 

When you count the savings in a hourly rate it's not that many. Shop labor is what....110-120 a hr. They quote you an hour each for front and rear. Plus tax and recycling fees. So twice? Plus if you tow regularly it would be in your best interest to change it frequently.
