Holy crap man, that sucks! How did that happen?
After the RC meetup, we were driving back home and had horrible vibration coming from the front end. I couldn't source the cause of it and thought it might be a unit/wheel bearing. Took it to 4WP and found that the pinion nut in the front had backed out but not come off. That caused the driveshaft to vibrate. Also, the pinion nut allowed differential fluid to leak out the front diff which led to the Rubi locker frying, literally! All the clutch packs melted and fused together. The vibration caused the teeth in the R&P to get out of alignment and chewed up some of the corners.
$3500 later, I have upgraded to 4.88's in both F&R diffs and added an electronic OX locker to the front because I couldn't just run an open carrier and the OX was the cheapest upgrade without also changing my spline count on the front axles.
I had thought that I could just run an open diff and save the money for either an ARB locker or just upgrade the whole damn axle assembly to a Dynatrac or Currie 44, but the Rubicon axle won't let you run the front open.
Live and learn I guess. Just disappointed in the result from an otherwise awesome weekend. I'm still waiting to find out if the cause of the nut backing out is the actual JE Reel being out of balance. If it is, I'm going to get it rebalanced and then bitch them out. If its not, then it's probably user install error (being me).
