You original 2 points were:

To cure a vibration, the front and rear flex discs must be replaced along with the center bearing.

A drive shaft removal is difficult for a DIY especially without a rack, partially because the exhaust needs to be removed.

My points: ( without malice )

While inspecting my _spare_ drive shaft I noted that the center universal joint didn't flex freely and felt notchy. I then went on to state that the notch _could_ cause vibration.

The center universal joint caps are retained by staking the yoke, something that is difficult using normal shop tools. I then asked if an aftermarket u joint was available.

In a second post I addressed that drive shaft removal wasn't an issue and gave an example of how GM used to lock caps and the field repair method.

( Again, without malice )

I am sorry... it's just that there are not universal joints in my car....it's the flex disks that join the drive shafts.... and the center bearing is not a universal..it's just a bearing inside a bracket....

Maybe I am confused... I had this problem in my 300ce.... i was certain it was a bearing problem...but when they told me the exhaust had to come out , i went ahead and got the flex discs..... the front was about to break apart... the rear was fine....

that's my experience.... the indy charged 400... plus i gave him the parts....

i thought it was a fair deal...

There is a universal joint in the MB two piece driveshaft and it is staked into place, The ends have guibo discs and the centre hangs off the carrier with a bearing in it.

The U joint is staked in place and requires grinding and restaking to renew. Very hard in field, Some members have replaced it with some ford application U joint but its a very hard job. Best left to a driveline shop that can repair truck shafts.
