Blake, remove them! now! After removal check for dirt in between the CV and
the tranny and on the wheel side. I think one is not sitting properly.

I say NOW because i had a bad eperience with one not properly installed, it
basicaly expoded on the tranny side.

If no dirt in between, it take only a few miles so they come kind a smooth
and loose so check if they are as tight as before. Also, if they are clean,
moving smooth (CV movement), swap them:

Something is wrong, good CV don'T make vibration or noise.

Still, i have my doubts on those 1 piece drive axle EMPI...

I prefer LOBRO or some German one. Those cheap one sell for as cheap as 20+$
at CIP1, i had them on my 79 (only on 1 side), a month later.......pffffff,
men, you should have seen the "play" they had.

Cheers, Ben
