Just wondering what everyones carrying for spare u-joints?

I have superior evolution axles in my front d44 and the u-joint has "SPR549" on it. Tried doing a search for this part but got nothin.

I have rubicon express front and rear 1310 driveshafts. There are 3 u-joints on either side of the t-case for 6 in total. They have no part# on them but all look identical.

Any ideas on what u-joints will fit the above parts?

Has anyone ever broke any of the above u-joints?

Thanks

 

if you got your superior shafts a while ago, they most likely have the old 760 u-joints and they are pretty easy to find and cheap. as far as your drive shaft goes, you just need to get 1310 u-joints
