Generic part number is 1310. You can measure the width to be sure. http://knowhow.napaonline.com/know-h...u-joint-guide/ Are you just replacing the one at the differential or rebuilding the shaft? Pay attention to which side the grease nipple faces, btw. If you put the joint in backwards you won't be able to get the grease gun on it. (Not 100% sure since I haven't had my coffee yet, but I think it faces the drive shaft).

i always go with the non greaseables. then just grease the caps with high quality grease before i put them in.

now, you have two different u-joints. you have the 1310 joints that go in your drive shafts, also a centering ball in the front double cardon joint. you have 3 plus your centering ball in the front shaft alone, and 2 in the rear shaft.
then you have two in the front axle shaft. those are spicer 297x or 760x, either will work, with the latter being stronger, and a little more money.

just don't by the cheapest joints, for obvious reasons.

Go spicer life sealed joint. They'll cost you about a 20 dollar bill per joint but when you think about how long the OEM non serviceable joints lasted, is that really a big deal? Why deal with grease zerks when the sealed spicer joints will last 100k miles?

Thanks so it 760 in the axles shafts and 1310s in the front and rear driveshaft

Huh? That depends on what one you are trying to replace.

yes. correct

if they don't have the 760's, you can use 297's
