My new 11 850xp whine?

[jp850xp]

Just curious i finally put a few miles on my wheeler this weekend, is it common for there to be kind of a whining noise coming from somewhere in the rear? especially when letting off the gas, kind of annoying if this is normal

yes but check the oil level in rear diff, mine was kinda loud when I first got it, stopped and checked all fluid levels and ther was very little in the rear diff, changed oil and over filled it a little with synthetic 80-90, quieted down aloot, probably saved rear diff too

Mine whined when it got water in it.

Super easy to change.

Mobile 1 75w/90 synthetic or also known as GL5 gear lube at any auto parts store. 1 quart will give you 3-4 changes. Drain from the bottom and fill from the upper. It really helps to go ahead and get an marine outdrive pump. Also available at any autoparts store for about $10. You'll need this pump to put the front diff and transmission fluids in also.

yes, it is normal.
