4l80e U Joint I can't find the u joint I need to join my stock DS to the 4l80e yoke. I went to NAPA and they ordered one from their conversion chart. The end caps work but the length of the joint on the 4l80e yoke is too short. I'm tired of searching can someone please help?
I should add the 4l80e and yoke are from a 2002 GMC two wheel drive 3/4 ton truck w/6.0 engine.

There is a way to match the u-joint with measurements. I think you can find that through driveshaft companies like Denny's that show what measurements are required to know what you are dealing with. Hope that helps.
Here is something to work with. THere is more info on the site.

Thanks for the link. I did take measurements but cannot find anything. The measurements refer to a S44 on the driveshaft and a 1410 on the yoke side. Guess I have to order a different yoke.

Gee, didnt think the yokes were that big on those trucks. Yeah, if nobody has a conversion joist then i think you are stuck. Try any truck or industrial shops? Even like the offroad 4x4 shops may have something.

I ordered mine from Jake's Performance and it fit on the output shaft perfectly. Maybe your output shaft is non o-ring'd but I'd check before you go trying to slide it on and then find it won't fit.
