2015 Polaris Sportsman X2 570

— Started making a grinding noise

1 month left on warranty! — Whewwwww

They started offering the 5 year warranty 2 weeks after I made the purchase!

Here ia a pic of the Left Rear:

Hear is a Pic of the Right Rear(Looking like its got problems with fluid leaking)

Anyone ever hear of polaris offering a free extended warranty on manufacturing defect this early on?

Will the rear end need replaced as well?

Would you buy the extended warranty?

Any reason to worry about the front ones?

Thank you
