we looked at the tech tip and the 1/2-Ton Truck 3:55 Ring and Pinion Installation will show what we are having problems with we can get the assembly into the tube. under assembly the picture shows the more inner bearing and under that the retainer to keep to lock in assembly but we can not get it to drop far enough to install set bolts both of the bearings are in the proper location there are no edges or imperfections to stop it from sliding we even like stated before applied a thin layer of grease and still no success. any thoughts?

thank you
