It wasn't overfilled when the hooning occurred. The whole "overfilled" thing is weird... I mean, I don't even see how I (anyone) could overfill, you just fill until fluid is pouring out of the top hole. But, the fluid on the diff must have come out of the blow off valve because it definitely doesn't leak.Detroit wrote: ↑Tue Jul 24, 2018 12:14 pmI suspect it's pinon bearing failure. Especially if it happened after being hammered on. If the fluid was overfilled, it might have gotten too hot and thinned out to the point where it wasn't properly lubricating the bearing.Tarspin wrote: ↑Tue Jul 24, 2018 11:56 am
Weird man. How do these things fail? They have a ring gear and a few bearings. If there were noise on a factory spec unit you'd think there's some metal in there.
At very least I'd get a second opinion. Maybe it's not a big deal? My diff didn't make any noise before or after gearz.
I don't see what I could do about this though, no real way to check it without opening up the diff, at which point, may as well just go with the 4.10s because you're already paying good money. So I'm pretty much just until it breaks, if it needs a tow, it needs a tow.
