DriveShaft rear u-joint
 

Can anyone answer. If the rear u-joint can be replaced. And if so, part#. I been looking all over and haven't found a single video or guide of it being replaced. Some places say yes and others say no it cant. It was put in some how at factory so it should be able to be taken apart.

How'd ya break it?

After changing the CSC it got bolted to the diff 180° out. Do to being rushed out of the shop i was using. Didnt notice untell a vibration started about month later. I swoped back. But the joint is shot now.

no help really,
a metal u joint into CF composite driveshaft must be using some really heavy duty glue
i would assume to remove it would destroy the shaft.

but how would bolting 180 degrees matter?
i can't think of any reason a u joint would have to be bolted in one way vs another
what would you do if you replaced your diff? not like the diff/drive shaft are balanced together or something.

Forgot to mention there was clearly clean metal were there use to be a wight mounted. This possibly is the main reason. U can see all the grease in the pic also all splattered. https://uploads.tapatalk-cdn.com/202...dbc51268e8.jpghttps://uploads.tapatalk-cdn.com/202...087bb1446b.jpghttps://uploads.tapatalk-cdn.com/202...f8c56c4109.jpg

If u look in the FSM it is recommended if there is any vibration to rotate 90° on the 4 bolts drive and rotate if not fixed. So there something from factory they know.

You can replace the universal joint itself ... in one of the photo's, you can see the circlip that retains the bearing cap (there are 4 caps ... 2 on the piece that bolts to the diff and 2 on the tail-shaft itself).

If there was a weight that balanced to tail-shaft and it has disappeared, then you need to get the tail-shaft re-balanced

Google found me an example on first search:

I been looking in my area for any shop that will balance it. But as soon as i mention 370 carbonfiber drive shaft they say they cant do it. Us there any part# for the barring caps?
