changing u joints/tapping stock with grease nipple

[highrollin113]

so i attempted to change my u joints on my rear drive shaft on the weekend and to no avail i could not get them to budge(well i only tried the rear one) does anyone have some advice for me. also the replacements are greaseable does anyone know if i drill into the stock ones are they hollow and then can i tap a grease nipple into it and make them greaseable??? thanks in advance for any help

No do not drill any holes in the U joint, Matco makes a air chisel tool that will remove u joints real slick.
