Anyone running these? RCV

[Ghostbuster]

4 front diffs zero CVs for me
Bebe 3 front diffs zero CVs
4speed 3 front diffs Zero CVs
08 H3 I believe had a front diff go with no CV issues

Don't all of y'all wheel the majority of the time on rocks and stuff?

What causes a diff to break? Tons of wheel spin and then when it does gain traction it breaks the diff?

Yep, pretty much.

I just bought the Cardones for spares ( Black Sheep week). While on Rock Auto,they had the oem shaft only for $ 75.00. My originals with 90 k are still fine. The type of wheeling you do, has a lot to do with it. ( Opinion only) I don't have a lot of rock crawling near me. I think this is one of the reasons I haven't had problems .

Yep, pretty much.

I blame automatic transmissions. ;-)

Bebe and I wheeled rocks, 4speed I believe more mud but idk what he was on when he broke. Diffs will break due to shock loading like spinning then grabs hard. Problem is I never broke from shock loading I believe it was more of an accumulation of abuse. I wheeled a lot and it just wore out over time

Chris you push that poor 3 past hell and back. Not sure why you break anything . HaHa

My first break was at 2300 miles with stock Duellers, on level ground, in 3"-4" of mud. Got pulled out by a Caterpillar....drove home in 4Hi-lock. Ended up being a snapped d.s. stub shaft. Moron crew at GM fixed it.
Second break happened at 20k while climbing a rock ledge at the Badlands. This time I spun-and-snapped, with 35"s Same issue...stub shaft. Drove to the dealer and was told it wasn't covered.
Told the service manager to suck my balls, drove home, bought a used 06 AAM-7, put it in myself with a Rancho. It lasted until the SAS at 42k. Still worked great when pulled.
At 42k...pulled the Rancho and did the SAS. Problem solved. It's much stronger and also geared to handle the 37"s, so there is no tranny hunting or downshifting on the highway.
