Front driveshaft issue ?
Hi
After replacing the front cat on my cayenne s ( passenger side) all seemed to be well even tho it was the worst diy ive undertaken to date until i took it for a drive. There seems to be a shudder when driving almost similar to a flat tire feel. I had to remove the front driveshaft or cardan shaft to gain acces to the flex pipe from the cat. Im pretty sure the driveshaft went together ok but im concerned something isnt right there. Anyone have any experience with this ? All was fine before the removal

Eilenberger's Law of Troubleshooting "Look where you last worked.."
If it was OK before disassembling the front driveshaft and it's not now - I believe that law applies.

Yes thank you that’s the plan. Do you know if roationally it has to go on a certain way ? Some research showed apparent marks on the housings and shaft that have to be aligned but my thinking is the shaft should be balanced so wouldn’t matter or am I missing something ?

Yes. It has to go together the way it came apart.
It's not so much a balance issue as a 'synch' issue.
If all the CV joints aren't lined up right, you can get some interesting vibration issues.
