On my sled, what are you guys using for replacement or the bearing #'s for the ones that can be replaced. All of the bearing are noisy, I will replace bearings in those that can be and replace all the other ones. I cant find #'s for the upper carrier rear wheels. I would like to find replacement idlers that dont need any modifications.( Polaris ?? ) Any help would be a free beer in Hurley( after riding ) jan. 20th---27th or just a big THANKS. ( your choice )
