YETI CYCLES SMALL PARTS
Like many others, the Yeti 575 uses sealed cartridge bearings in the pivot points for the rear suspension. The bearings are sealed units, but they are not impervious to wear and or corrosion from a number of elements. Bearing longevity is a direct correlation to how much you ride, the conditions you ride in, and how you wash your bike. Put simply, go ahead and ride the hell out of your bike through the mud and anything else that gets in your way, then wash it at the carwash, making sure to blow all the grease out of all the bearings.
It's your bike, but that’s the fastest way to need one of these bearing kits. Most folks will actually get a good year or two out of the bearings in their Yeti before they will need replacement to get the bike running buttery smooth again. You may never need them, but if you do, this kit contains enough Enduro Max pivot bearings to replace everything in the rear suspension for your 2008+ Yeti 575. Simply remove the old ones and press in the new ones.
