U-joints and where to buy

[bhedberg]

Any suggestions on which u-joints to buy for the half shafts and the drive shaft and where to buy them? Seems the part numbers have changed over the years. The 5-627x and spl30-1x are shown as obsolete.

Spicer seems to have shuffled the part numbers around some on the 1310 and 1350 series u-joints. Basically you want the ones without the grease fitting in the cross and for the aluminum d/s and half shaft applications.
I was able to recently get the d/s one as 5-1310X (new number scheme).

The half shaft u-joints I bought were listed as 5-799X units. They fit so nicely. They might even be the ones listed for the steel half-shafts, but they have been doing just great.

ON EDIT- the aluminum shaft application calls for 5-800X (if you can still find them). They have a galvanic coating on the bearing cups to prevent issues with dissimilar metals. I wouldn't worry about it, but if you want a real problem throw in some $10 imported u-joints and hog out the eyelets a couple thousands of an inch from oversize dimensions.
