I think its time to replace my u-joints. I have no problems with doing the job,but I have a question about the joints themselves. I've read the Adults Only u-joint cross reference thread. I'm usually the "I'll pay the extra for the marine part", but in this case, it seems like it may be moot. I know Don likes the Spicer u-joints, but my local sources have Neapco, Napa Premium, and Precision - Moog parts. Are these good parts, or should I bite the bullet and order the rockwells? I am hoping to get these replaced before the weekend and ordering will pretty much quash that.

Ok, I've checked all major auto parts places around me and no spicers or Rockwells. Only the ones noted above, Precision Moog, Neapco, and Napa Premium.

Opinions welcome.

IMHO - any of them should work. The only thing to watch for would be where the zerk is located. In the end cap probably won't work, not enough room in the bellows.

The NAPA Part# is identical to the Precision. I have read that NAPA has dropped Spicer, but I don't know that for sure.
