Hi, is this a legitimate question?
This forum has been dead for a while, and the 808 is ancient now hence my asking this.
If yes, then the answer is definitely to ditch the entire old setup and switch to the 808 '11+ design where they went back to traditional 8x16x5mm (x2) diff pinion bearings. Xray made a mistake on this buggy here, and thankfully they recognized it from 2011+, and for the last entire decade has probably had the best drivetrains in the business. I hope they continue to use the 8x16 instead of switching to smaller bearings like other manufacturers.
I had to deal with the same mess in the past myself, and this was my solution which lasted a very long time.
viewtopic.php?f=9&t=12537You can use XT8 or XT9 10T pinions from any year model including current 2017-2019, they are compatible with your 43T 808 ring gears.
For the center shafts you can use any XB8 center CVD from 2011 to 2019, ideally choose newer ones (XB9 '13 through to current).
You can't use the 808 ones any more as they are too long, but ditching that entire inferior design is worth it.
The parts compatibility on these vehicles is amazing, diff casings still use the same pattern which I really appreciate.
If you don't mind spending the money again, I recommend just replacing the casings instead of doing what I did in the above thread, I eventually replaced them.
The design of having the bearing seat in the middle of the two bearings is just superior. The original design as I said was just a mistake, all the recommendations / spacers / tech tips just delay failures, the real solution is to switch to the updated design. Good news is once you do that, it will last for many years.
Best wishes,
Udi
