Hey guys just bought a 2011 rzr 800s yesterday noticed its stuck in 4wd. Jacked the back up and tried it, still stuck. So I unplugged all the wires that I could find that went into the front diff and t case still nothing. Drained the diff fluid couple metal chunks so I ripped it out today, when I got to the part of taking the drive shaft off I could turn the input of the diff by hand it would lock up by it self(bike was in 2wd) put the bike in 4×4 and I could barly turn the input for the diff it was real hard( tires a arms axle shafts out already) so I tore the diff down found a few long think chunks of steel and noticed the cage has a couple very small cracks in it, would this be my problem? Thanks for the help in advance
