Hey guys, so I just took my 2018 rzr xp4 1000 to Pismo dunes for the first time and was very dissapoint….it ran great in 2wd except when you were cruising at a steady speed it had a bit of a rattle that seemed to come from the front drivetrain. However when I put it in 4wd it would be fine when cruising and then under hard acceleration it had a terrible vibration. My guess is a bad u-joint but would like some advice on how to get an accurate diagnosis. Thanks in advance for any advice.
