Gottcha
It didn't start out too bad and it wasn't noticable until about 70mph. It did get progressively worse until something totally blew out at around 1500 miles or so.
Ok well I'll keep going with my plan to fix the front first then remove the rear shaft and see what it does. I'm at about 500 miles on the new gears so the last thing I want to to be driving down the highway on a ticking time bomb
Sorry man, I wish I could help... It may have been that the shims weren't right in the first place or it could've been shitty bearings. I was supposed to get Timkin bearings with the package I bought but they ended up being some other brand (don't remember the name). Apparently it was the same brand the factory uses now, but my guy said that he's even seen bearing failures in new JKs with these in them. The replacements sent were the Timkins that were supposed to have been there from the jump.
You still have the stock driveshaft? Is there grease slung out on the gas tank?
Stock rear shaft. No grease slung out that I have noticed
Not too sure I have never had a shaft balanced. But I imagine it would be cheaper than buying new arms to correct the pinion angle or having the rear diff looked at so that's probably my starting guess.
COULD cause a vibration. generally, 1°-2° between the driveline and pinion is what is recommended. but again, if this isnt a new pinion angle, I think if the angle was the problem, you would have had the vibration all along.
I did check the pinion when I pulled the shaft and it seemed to me (in my limited knowledge) that it's all good but I will check it again. The little torque paint they put on the pinion nut hasn't slipped either.
Yeah so litteraly the only thing that changed was the re gear.... since its the stock driveshaft and not a U joint shaft I was thinking that 4* wouldn't be too bad but now that the shaft is spinning even faster with the new gears maybe it is. Thats kinda what drew me to think out of balance shaft if it was ever so slightly out of balance and now it's spinning faster it's causing the vibe.Its MOST likely the driveline itself if nothing else has changed.
But 4° (Hold Alt while typing 0176)
If its the rear diff bearings, the sound/vibe would likely still be present when you drive, that wouldn't go away just because the shaft was pulled... everything still rotates.
