I've got a 99 Suburban (OBS) 4x4. It's got the auto 4x4 also. When in 2wd the light on the switch goes out after a minute or so. It comes on every time you first start the vehicle, and then goes out a short time later. Is this common? It didn't happen on my previous 99 Sub. Is the switch going bad or is there some sort of sensor? Even when the light goes out, I can tell it's still in 2wd.

Thanks

- Fluid Change Questions

  I bought the truck new in December 2022, and it's got 60,000 miles. The front cover magnet had slightly more glitter, but overall very clean, no off odor, and good-colored; really nothing to report. My truck has Hi-Lo transfer case, and the fluid looked great, as well. I have towed..maybe 1,000 miles. Yes, this was the first change for all three driveline items. I'll probably do the transmission at next oil change.

  Would this be the first time both the diffs and transfer case oils were changed ( that is if you know the history of the truck since new ) and if so how many miles are on the truck now. Also and of course that would make all the difference if this was the factory oil or had been changed prior, what volume of wear metal fine paste like substance were on the rear vs the front diff cover magnets. So far I have drained the rear diff oil and the transfer case as I said above at 9000 miles but don't have a clue what would be on the front diff magnet and would be speculating to guess it surely couldn't be near as much as what the rear diff magnet had on it due to it going along for the ride a large part of the time. The transfer case I have has the 4 auto feature which I have tried to avoid using as much as possible due to warnings about the clutch pack slippage wear that takes place, certainly I saw some discoloration of the oil but it still easily identified as red fluid but the fact it has no magnet isn't impressive but I think most transfer cases over the years never had a magnetic plug.
