Highest Mileage on a BW Transfer Case?

[t77911s]

I'd like to know the expected mileage from a BW Transfer Case without a viscous or chain replacement? I have 129k on mine....

I have no idea what the expected mileage for a BW tranfer case is but before I changed mine out to a LT230 I had 219K on it.
It still works fine.
If you change out the fluids reguarly (5K) then I think you will get a good life span out of it.
