U-Joint size with 45RFE?

[ShafferNY]

Does anybody know what size U-joint my '03 Liberty with the 45RFE transmission uses?

I'd rather go pick up the parts I need before I take the driveshaft out, rather than take one of the old u-joints with me to match up.

Advance Auto lists two different sizes for my vehicle. I believe this is because in '03 the KJ could have either the 45RFE or the 42RLE transmission, which translates into two different driveshafts. The sizes available are 3.622 & 3.219.

If I had to make an educated guess, I'd go with the 3.622.

All KJ's use 1310 u-joints on the rear driveshaft,42RLE or 45RFE it doesn't matter.

I wonder why they list two different ones online then.

There are 2 different yokes used in the KJ, one is a 4" and another is a 3 1/2".
Can you pull the P/N from your old U-joint? The Spicer 1310 is 3 7/32".
