Got my new 1K 2 weeks ago. Front Diff. noise was bad, just like what has been described here many times "rocks in a can". I was pretty much expecting it cause I’ve heard so much about it here. Even though few failures have been reported, its down right annoying with that constant noise coming from the front end.

I took it into the dealer to have a winch installed, and told them to check out the noise in front end. They did and determined it was in the differential. Filed a claim with Polaris and 2 days later it was approved..New Front Differential ordered, however it was on backorder. I said fine I’ll wait.

Got my 1K back today with the new Differential and its like a whole new machine, completely quiet front end so far, I havent hit it hard yet, but the original Diff would started rattling at anything over 10mph and this is definatly an improvement.

BTW dealer told me the Diff had a new part number. And also said it appeared as if it was pulled off from the assembly line. So I guess we can assume new 2016 1K’s will NOT have the noisy Differential issue.
