Well it was a rough week for the nytro in the UP Last week. Had the LH upper ball joint come loose while going down the trail, One spindle and ball joint replaced. Next day i was running the power lines off trail 3 in twin lakes, hit something and bent my perty red grizz frame. On the way to pats yamaha in greenland to see if i could get a subframe my RH spindle came loose, wtf!!! So i spent half a day puting a used subframe on and 2 new spindles w new bolts, nuts and washers. Gone is the perty red subframe for a 2010 model subframe and stock silver spindles..... LAME. Then the last day of the trip i rolled the sled on its side on a icy road and broke my windshield and bent my handlebars. UP was a cruel heartless bi*** this year and i enjoyed every minute of it. 1500 miles in 5 1/2 days of riding/exploring. FYI, IF you dont care about replacing your spindle and upper balljoint as a pair fill the hole around the bolt with JB Weld. Makes a solid spindle and ball joint mount that cant come loose...
