On some vehicles, the U-joints can’t be serviced. Instead the driveshaft is replaced.

What kind of vehicle are you talking about?

For several years GM used epoxy to hold in the factory u-joints. Heating softens and expands the epoxy out the holes it was forced into and releasing the bearing cups.

You have to hit them hard with at least a 24 oz. hammer. It will work easier with heat because that’s what you do to epoxy (plastic). Some parts will be easier than others.
