Thanks for taking the time to take a look. I have a 2004 grizzly 660 and am the original owner with over 4500 miles on it, hauls wood and tows spliter for ten cords a year, plows a 1400 foot drive way as well as hard playing. That said it owes me nothing. However I continually have the common problem of the rear axle popping out, mainly the right one. Ive been reading about this for years, Ive pulled it, cleaned it and stretched many of clips over its tired life,,,I haven't tried the gorillia square clips manly because so many people say they didn't work. My local yamaha dealer tells me they dont have any beefier replacement clips. I haven't tried the rubber band under the cir clip yet because i just hurd of it. The spline on the drive axle seams to have some wear on it now and the last time i pulled and cleaned it there wear significant metal shavings in the diff case. I didnt think to put a magnet to it to see if alum or steal. Im at the point wear i need to rebuild the diff and get at least one new axle but the re build kits arnt that much cheaper then an aftermarket new one. Does anyone have any experience with the after markets and would this fix the axle slipping problem if i just went with a new one. I read about a guy who said that problem was fixed for him by removing the dust shields which is a commitment and wouldnt that lead to other problems of contamination . Any one else try that with vicory? Lastly I currently run a 50 inch straight plow and wanted to upgrade to the sixty inch county style, i keep 120lbs of weight on the rear rack while plowing and have very limited problems clearing snow. I think it could handle the extra blade. Anyone out there have that blade on this machine? Thankyou very much to anyone who made it to the end. This has been such a long frustrating reacquiring problem for so long, besides the walking axle that quad is a beast!
