Driveshaft rebalance after center bearing replacement?

[ALEV8]

Replacing center bearing and flex disc on my 04CTT. Should the shaft be rebalanced before reinstalling it? Don't want to spend extra money on this but not sure it's necessary. I did not have a catastrophic failure of the shaft.

If you are just replacing the bearing and have not other damage, it should not be necessary.

Looks like there is a boot on the CV which needs replacing and my indy wants to balance the shaft after all. I've not seen a CV boot mentioned in any of the DIY articles....anyone?

If they noted the relative shaft positions when breaking it down....  and reassembled them in the same orientation, then a re-balance shouldn't be needed.

Wonder if the reman shafts get balanced again?

No need to replace the boot unless it's damaged. I use a laser level to mark the shafts in a few locations to be sure it goes back together indexed correctly.

Mechanic couldn't get the bearing centered and gave up after two tries and failures. Pretty sure he screwed up two of the bearings and the new boots. Doesn't seem that hard to me but I went ahead and ordered the reman unit from Vertex. I lost money on the parts from ECS however all my labor is comped for this job and the previous vacuum line install behind the engine cowl.

Still seems like a very straightforward job and my mech talked me out of getting the entire driveshaft reman and swapping it out in the first place. So he was wrong.

ALEV8, I see you are in Dallas.  What shop were you using?

My guy came from Classic and bounces around. Unfortunately I haven't broken up with him yet....
