It still has the factory fill, which I think is 80W-90, but would like to use the 75W for winter & wondered how it would perform & hold up with the traction lock differential & sound, if any, when in use??? Would be interesting to hear any inputs, good, or bad, you can muster as your use progresses.
Any evidence, or idea what might have caused the ring gear mischief????

I'll keep u updated. As far as the old rearend the truck was beat on. Underneath was covered in mud. I would say it was used in 4x4 mostly. Not sure on lift size but they put 17 in jeep wheels on with 1 inch spacers and 255 75 bfg mt. I paid 680 for the truck. That's what he owed les schwab. Motor runs real strong and everything works. I'm gonna use it for hunting as soon as I trust it. Put about 60mi on it today running 65.
