I had to remove my front drive shaft and the bearings on these joints all fell out and the whole thing will need to be replaced.

I'd love to buy some new ones but I'm not sure what theyre called.

my bad, heres the picture

 

Universal joint.

 

Thank you very much

 

I've been there Red. Now when I remove a U-joint, I wrap tape around it so the caps don't fall off.

 

if the shaft for the cap isn't worn and if there isn't any broken needle bearings and if you haven't lost any needle bearings lay a light coat of grease inside the cup and reinstall the bearings - it's easy and simple too do
