Hi all , any "How To" on how to check the Front Diff , seem to be getting Noise and vibration
2015 ZForce 800 , 2500 km
thanks

[2015 Z Force 800 53/Trail EPS]

All had some loose parts in the drive lines and many lost their carrier bearings. Mine has had loose splines sense new and have gotten a little worse over the years. Can always pull the plastics and check but a quick test to see if it's in the drive line is be moving in 4wd, preferably up hill so you can load it, monumentally take your foot off the throttle and reapply a couple of times. If the vibration changes..ie gets worse or less when the power is reapplied, its likely in the drive line or..in a CV joint. If no change, it's probably in the differential or..more commonly, the diff is coming loose or has broken a mount.   

Well when I blew mine, I rebuilt it but found a second whole diff for $250. I put that one in to use while rebuilding the old one. The used one had 3k miles on it. The used one for sure has a decent amount of vibration. Probably bearings but I will run it till it breaks then reinstall my rebuild. My rebuild did have one chipped ring tooth so That's why I opted to just toss a used one in and have extra parts.

the noise was/is coming from the Steady Bearings, lots of play , as well as the 4 universals have a littlr play
