So I hear a rotating knocking sound, get out to find the cap fell off the front passenger side of the U-joint. I have read on here that they are "around $20" but when I call the stealership they quoted me $99 and Autozone says they don't carry them.

Can someone help me out with a part number or something that I can get this U-joint?

 

The factory joints are actually spicer joints , dont know the model number.

 

anyone have the model number to these bad boys?

 

boom...oreillys had them for !6.99...screw you autozone!!!!!!!

 

Which U-joint size are in them?

 

I jeep a word document on stuff I might need to remember for my jeep and found this:
Sorry don't know where I stole it from... And its rather embarrassing because its written in word and for a living I tell people not to use word..

part of the reason your u joint cap came off is because oem type joints come with c clips instead of full circle clips but the main reason they came off is because they used less than ideal materials to manufacture there axleshafts,this leads to the bores becoming oblong and allowing the caps to spin in the first place...the only real way to correctly fix your problem would be to upgrade to a set of cromo shafts as the bores in yours are already out of tolerance and installing a new joint will most likely result in the same thing happening...if that upgrade is not in the budget now then you can tack weld the end caps and that should keep your caps in place...hope this helps...

 

Awesome list. Saved to a Word document in your honour.

 

Would this info apply to a 2012 Sahara front axel, has anything changed? Thank you.
