I tried searching in google and I have no found anybody having similar problem. So my sled is a 2015 model and I did grease my rear suspension through the zerks multiple times last year. Now I am trying to prepare my machine for a new season and there is no way I can get any grease into the zerks. It seems like they are clogged or something and all the grease is coming out at the chuck of the pistol grease instead of getting into the zerk and inside the suspension. This is a professional pistol grease of a german production and it worked perfectly last year, this problem is showing at all the zerk locations. Any idea how to go around it? Do I have to disassemble entire rear suspension to figure this out? any help would be appreciated
