Does the rear slip yoke just slide off or is there some type of retainer ring holding it on? My is really stiff and won't slide at all I have to tap it with a hammer to get it to move. I broke 2 U-joints so far I think it's because it won't slide. Was gonna take the yoke off and clean it then grease it. Thanks

 

should slide off

 

The retainer is probably pressed on.
