Pull up a chair and get comfortable Jonfinnell. I give you my tales of woe on my TRE propshaft.
Stock prop shaft. 1000 miles. U-joints in front shaft failing.
Found out front u-joints not available. Have to get the entire shaft. Went to a driveshaft shop. Best match was u-joints for a Kubota tractor. Had them rebuild everything.
Lasted barely 500 miles. odd-ball u-joints coming loose.
Spent big bucks on an RCV CV 2 piece shaft with their carrier bearing.
RCV carrier bearing failed 400 miles later. Most likely because you can't fit an installed carrier bearing through the frame on the shaft. Have to install it in the vehicle. Don't think I got it installed correctly.
Switched to a SandCraft Gen3 carrier bearing on the RCV shaft. Worked real good for about 2000 miles then this.
Send RCV prop shaft back to RCV. They rebuild. Re-install with Gen 3 carrier.
200 miles later-
Switched to SATV Rino shaft with their SATV "billet" carrier. Its a solid mount carrier. Noisy as hell and you can feel every buzz & vibration.
At this point, today, I'm in the process of shimming the front diff, going to run the SATV CV shaft with a rubber OEM style carrier. Just got my spacers back from the machine shop to run a OEM style rubber carrier. The stock style rubber carrier needs a spacer behind the bearing on the SATV shaft.
Pro4 has done something very similar to this.
Highrider is running the RCV with sand craft carrier (like I did at first) and seems to be having good luck.
I seem to have the worst luck with my prop shaft but, I really feel shimming the front diff (sand craft makes a shim), rubber OEM style carrier and the SATV CV shaft is going to do the trick.
I'll toss up a couple pictures in a bit of what it takes to put the rubber carrier on the SATV shaft.
