It might be. Honestly the birfs are probably the weak link but so many are upgrading the birfs and inner axles to chomoly ones that it makes the diff the more likely weak link. All said though, it's almost always some really hard driving (whether it's a difficult crawling obstacle or something else) that breaks the diff. Mine broke when jumping the truck (not on purpose, just driving fast and got airborne). The landing under power shock loaded the diff. At least there are things like cryo-treating or REM surfacing that can be done to the diff gears to strengthen them too.That must be the weakest link on these trucks, that’s the third one I’ve heard of blowing in as many weeks
Yeah, no matter how you slice it, it's a small crown and pinion and size is a factor in strength, especially associated with shock load. If there was an easy upgrade (like there is for birfs) it would just reveal the next weakest link in the driveline.It might be.

Haha. I wish I had spare cash laying around. I did some work for a cruiser shop and they happened to be stripping an axle and I took the diff in trade for the work with plans to use it in the front axle of my son's minitruck. But we never got around to putting into his truck yet. Gotta say it was nice to have it on hand to use while the new diff was being put together.
- If you have spare cash like Adam, keep a set-up 3rd member on the shelf at home ready to go.

Great idea! I got some more thermal shield to wrap around it as well. I wish badly that the harness was still available. I feel like I’m repining half the connectors lol.Shoot while you got the motor out and harness available I would double check the area of the harness where it runs near the EGR and repair now rather than later.
Hmm yea it seems like it might be preferred to keep the birfs as the point of failure in that case. They'd be a lot easier to deal with on the trail than the diff itself, especially if you can't disconnect the front hubs.It might be.

Doesn’t wits end sell the whole thing?Great idea! I got some more thermal shield to wrap around it as well. I wish badly that the harness was still available. I feel like I’m repining half the connectors lol.
Thanks for sharing that, I’ve looked at the OBD2 harness. I wasn’t able to convince myself to figure out how to turn the obd2 harness into the od1 harness (my truck). Besides I’m almost done replacing connectors lol. When I looked into it, I think the trans pigtails were different, the EGR was different, and the MAF/AFM were all different, and the crank sensor, and a few ECU pins.Doesn’t wits end sell the whole thing?
