One Cold North Dakotan
I've just been wondering what was happening when I heard a thunking sound coming from the front somewhere in the drivetrain when I got stuck in a snowdrift. I had my manual locking hubs locked before I tried to go through it of course, and when I couldnt go forward my friend and I dug behind it to back it up, so I was giving it alot of gas in reverse and it would kind of thunk a couple times every second or so. I don't think it did it when I tried to go forwards though. Seems to be working fine, just curious what it is.
