U-Joint Cup size?

[chris070780]

I need to replace my passengers side wheel u-joint. I wanted to buy the joint before I tore into everything and it looks like autozone offers two different cup sizes for the u-joint. They make a 1.063” and a 1.188” cup size. Any clue what size a 91, 4-door, auto, Eddie Bauer would use or does it very from truck to truck?

If you are talking about what is called position #9 (in u-joint diagrams) which is the front axle shaft u-joints (outer on both sides and inner on the passenger side) the specs are..

Bearing Cap Diameter (in) Axis 1 1.188 in.
Width Including Clips (in) Axis 1 2.188 in.
Bearing Cap Diameter (in) Axis 2 1.188 in.
Width Including Clips (in) Axis 2 2.188 in.

Thats for the Precision Brand.. p/n 371

diagram of the positions...

Rock auto has a bunch of options, so maybe check that out... (you get a 5% discount using the code in their sticky thread in the vendor section)
