Broski-I had no Idea you were going through this mess! We'll have to get together sometime soon, baby is on the way in the next couple days. CheersSuper stoked, got my third back already. The owner of the shop checked it out before disassembly and said the preload was still with in Spec and everything was as it should be,besides the ring and pinion. He said that it looked like shock load that caused the damage.

Looks dam good to me. Sierra gears were used and total cost was $650.00 parts and labor out the door. I'm happy & love small town living.
Waiting for the rest of my parts to come in from Cruiser Outfitters to stab it back in, should be her today.
Did a double take...... not seen the rear RCV axle before. Almost thought it was an odd looking stock front hub without the grease cap.Looked at previous pics (in this thread) to see what it looks like with the grease cap on. Did a quick search on RCV axles, but couldn't find a rear RCV, just fronts. Must be hard to come by.
Looking back through previous posts I saw that you had asked how I was getting the 15.1 V at my Puma air compressor. Didn't mention that my aux batt is an AGM and my alternator will charge it that high for a short time and then drop down to the normal 14.6 V. Forgot that part and that's when I snapped the pic. That high of voltage (over 15 V) can mean a voltage regulator problem if it stays high like that. My primary and aux battery are isolated. I run the Puma, winch, fridge, inverter, a 12V aux connector and a charge line to my trailer's battery with the aux batt. And it seems to do well. Just thought I'd clarify that voltage reading, because it is a little odd to have it that high.
Here's a picture of one of @spyduh RCV rear flanges ( not good ) Our set ups are close to the same and we are both running 39s . Seeing that picture of his flange is what prompt me to inspect mine.Did a double take...... not seen the rear RCV axle before.

I wonder if it’s a bad batch of heat treating? If either of you have hardness files you could check his vs yours.Here's a picture of one of @spyduh RCV rear flanges ( not good ) Our set ups are close to the same and we are both running 39s .

This should not have happened, and what is really baffling is that both sides totally failed like that.![]()

That brings the suck, but better than a shaft.Here's a picture of one of @spyduh RCV rear flanges ( not good ) Our set ups are close to the same and we are both running 39s . Seeing that picture of his flange is what prompt me to inspect mine.

The shaft was chewed up too. Lol that's 300M shaft on 4340 Chromoly flange. My 529s survived. I'll take it outside failure all day long vs inside diff going outThat brings the suck, but better than a shaft.
RCV is taking care of it and warranting my shafts. They are checking hardness before they ship them out to me.I wonder if it’s a bad batch of heat treating? If either of you have hardness files you could check his vs yours.
Bad batch makes sense, mine are a year older with many trail rides on them.RCV is taking care of it and warranting my shafts. They are checking hardness before they ship them out to me.
very first trip out. It had couple hundred street miles from home to Fordyce Meadow Lake and then it was done on WH1 and WH2. WH3 is where i blew my stock Aisin hubs, but by then I was trying to wheel up WH3 on front wheel drive and winch assistance. Has to be bad batch.Bad batch makes sense, mine are a year older with many trail rides on them.
Yours are new and failed first time out= bad batch ?
I hope we don't see more of this !!!
