Stock u-joint size

[fad2blk99]

What size are the stock u-joints in a front drive shaft on an '89 Blazer / Jimmy (Both in the CV and pinion yoke)?

Saginaw S44 in the CV

Spicer 1310 series on the pinion

Which one is considered a one-ton joint, 1350 or 1410?

If you want to classify them, a 1350 is a "1 ton" joint. Some newer rigs come with 1410s from the factory even in 3/4 ton trucks, but if you want to classify them:

1/2 ton = 1310
3/4 ton = 1330
1 ton = 1350
1 1/2 ton = 1410

If you insist on looking at it that way I suppose. Trouble with that way of thinking is that all front shafts use the same u joints, and Chevys generally don't use the 1330, the 3/4 tons usually have 1350 shafts.
