For the record, I'd hardly say that I "molested the shit" out of Marc's 2015 Monster xp driveline. I only added a pulley right before the bolted stationary joint at the front of the driveline. Everything else was bone stock. It had a negligible, if any effect on the UN-reliability of the driveline.
You can see the flex in the carrier bearing here,
when Marc was still running a bone stock motor:
If it was so reliable in 2015, then why did the factory rework the transmission output shaft seal and bearing, and reduce the number of splined slip joints in the driveshaft from 2 to 1?
C'mon Jim, you know I don't "molest" anything. My mods are always well thought out, and are never lacking in craftsmanship. I did a near identical mod to the Monster Mav, and it proved reliable for 2 years. It was problematic on the Polaris due to the lengthy driveshafts coupled together using
2 slip joints, and a carrier bearing that is softer than a baby's ass. For the record, Marc no longer runs an alternator on his Polaris.
I know you hate to hear me say this, but I'll say it again: Marc's ability to push a UTV at, and past its limits exceeds that of most the drivers in his class. Therefore, he will exploit any vulnerability in any UTE he drives. Anybody feeling differently can offer up a challenge to him to run a lap on any track of their choice in bone stock cars and see how ther compare. Offer up a cash bet. He loves that shit.
