First let me say I did search but there is so much information and so many post it started to get confusing. I have a 17 and in 2wd at 25+ mph I get the marble in diff sound. In 4wd i don’t get this assuming since its under a load. I see on the 14 and 15’s guys were removing a shim but then I see that the newer diffs have a different part number. Also read a lot about the driveshaft being out of phase and not balanced. I’ve taken it back for warranty work but polaris denied the claim and said it was normal. I just want to know how to fix it.
