I dealt with the shop in Atlanta a couple of times when I lived in Cincinnati. They replaced a staked UJ for me, but I didnīt like their sloppy way of placing the drive shaft balance weights so I had to send it back to them. It never seemed quite right, so after I moved to CA I took it to a shop in Sacramento that installed a UJ using a cir-clip. I would guess this is what you mean by "serviceable" meaning "changeable".

If you are interested in a UJ with a grease nipple, you can probably find it in either staked type or cir-clip. In the end, itīs the stress more than inadecuate lubrication that causes the UJ to wear.
