centering rear end

The Yukon aftermarket a body axles were (are) shorter than stock a body axles so they could not be used with factory style wheel bearings as they wouldn't contact the thrust block in the center. This shortness is also why they could not be used with early style sure grips that use two piece side gears, there is not enough engagement in the second piece of the side gear and they tear the spline off. Ask me how I know... My second set of Yukon's were the cut to fit variety and I made them the same length as factory and used factory style wheel bearings (I prefer them.over green bearings).
