When going through a bearing supplier how do you figure out the sizes of the old worn out bearings? I want to replace the swingarm and linkage bearings on my 96cr250 but the bearings seem quite pricey. Also do the lower shock bearings come w/ the linkage kits? How much of a difference should i see if the bearings on it now are shot? This bike swaps alot, could these bearings being shot have anything to do w/ the swapping?
