Gen 3 & R Front Differentials Grenading

[Clockton]

Has the forum heard about an issue with the Gen 3 & Rs front differentials blowing up? I don't have all the details, but I hear the badness occurs when in 4 wheel and hard breaking combined with engine deceleration that is blowing things up. I have heard of three occurrences and all were in trucks that offroad

Has anyone else heard of this?

I have not. I will say however that I dont like how my truck pulls when in 4wd... kinda bullchit. My gmc never acted like that.

I think I saw one post on here about a front pinion? I’ve noticed more vibration from the front in 4wd but that’s about it. Torque steer seems to be non existent but I’ve heard of that being present for some people.

Is the gen 3 front diff any different than the gen 2? Minus the torsen whether you have it or not.

Your GMC probably pulled to the side of the road a lot.

It did once at 26k. Motor went boom.... then it was gone.
However the Raptor had a trans replaced at 5k miles.... its just so much fun to drive haha.

Mine didn't, never had an issue and traded with 38k. It was a 2020 with a 6.2....oh and my HVAC worked EVERY SINGLE TIME. With that said, every brand has quirks. I might have gotten lucky on the GMC but the Raptor is still fun.

Your scenario is exactly what they have you do at Raptor Assault at least 10-20x in a day. They run the trucks 1 to 2 times per week for at least a few years…

The earlier case was 2009-2021 as far as I could tell.. maybe they changed something or maybe the site wasn't up to date but there's been many failures of front differentials.. the case is unable to deal with ring gear deflection on coast/decel/reverse.. I just put one in my gen2...

Based on this report, I’ve removed my front diff completely. It’s done wonders. Even cured the noise emanating from the speakers called music.
