Not that I'm hoping to have a rear u-joint problem after lift but given the age and condition of mine I was wondering if any of you use either of the following Moogs - (Precision Federal Mogul)

1) Moog Precision U-Joint Premium (greasable) #270 - about $9

2) Moog Precision U-Joint SuperStrength (greasable) #354 - about $15 but harder to find here

The second one has the grease fitting in the bearing cup and not sure if that would be easier to service, at the price I'll try to get the best I can if possible. Installation tips, dos and don'ts perhaps?

Might be something to have around the garage or in the spare kit anyways even if not needed right away?

Don't remember the numbers - but when I went to NAPA they pulled up u-joint with the grease fitting in the bearing cup for the front of the shaft and the one with the fitting in the cross for the rear.

The cup is easier to get to - but takes a grease 'needle' - not a standard grease gun fitting.

The "cup" fitting on front and rear would be ideal. They are messier to service, but much easier to get to as mentioned. The standard grease fitting is a PITA on either end for my KJ. I have the cup in the front, and standard fitting on the rear, and I wish I had changed the rear to the cup also because it's almost impossible to service.

I like these:

easier to service and supposed to be stronger. Win-Win.

Both times I've done the rear u-joint I have gotten the wrong one the first time. Make sure you get a good cross measurement before you buy. especially online.
