2012 Yukon - 40 miles on dry pavement & 4wd hi engaged

All it takes is to check the fluid condition then you'll know. So you're saying that from point a to point b there were zero turns made and no possible chance for driveline binding. The clutch pack in the transfer case is the weakest link

Drove my Burb(albeit an 01 model) from Louisianna to Alabam in 4hi in the bad weather...200miles. no issues- Always have used 4hi in inclimate weather in every 4wd i ever owned. Never tore up anything. I don't recommend anyone else do this- I am just saying I do- and it has been no issue.

And do you really think that the driveline doesn't bind at all even when you're off road or driving in mud/snow? It's an imperfect system, and shit happens even when you aren't on pavement. You might not hear it as much because the tires aren't scrubbing on asphalt, but the driveline binding a little is bound to happen. It's just part of the deal when you're driving with the system engaged. Unless he was doing figure-8's the whole time and the driveline was CONSTANTLY binding, he is fine. A few little turns aren't going to burn anything up. Get real.

In low traction conditions the tires slip and relieve the binding. If the tires can't slip on dry pavement something else has to.

I didn't say there is a 100% chance for destruction. I said to check the fluid for signs of damage.

Thanks for your replies. I will have the fluids checked and hope that I lucked out. Although a bone-head move on my part, a dummy light on the inst panel indicating the vehicle is in 4wd would be useful. The tiny light on the 4wd dial is not very obvious...

I totally agree, and was thinking about it just yesterday when I checked to make sure I had gone back to 2WD. There should be "AWD", "4HI", and "4LO" indicators on the dash, just too easy to forget, especially a day later or if someone else drove it and shifted and you aren't looking for it.
