Moog U-Joints

Hello,
Has anyone here used Moog U-Joints more specifically part number 280? I just bought some, and I'm getting the u-joints pressed in at a driveshaft shop on Monday. I believe they're greaseable, but I'm just wondering if they're quality u-joints or at least decent. I wanted OEM u-joints, but I wasn't willing to pay 160 bucks for two u-joints considering that the driveshaft isn't that difficult to remove, and it only cost 40 bucks to get them pressed in or free if I'm willing to do it myself. I just don't want to regret my purchase or waste my time if they aren't quality or at least decent u-joints. Any advice is appreciated thank you.

 

Thank you. How often do you recommend greasing them??

 

I'm assuming you grease them without taking the drive shaft off? Which grease gun do you use? From my understanding I know some grease guns are better than others.
