Need assistance with 97 328i center bearing

[SolTNutz]

Hope this is in the right section..
I have a 97 328i with center bearing issues. Under medium takeoff the center bearing rattles, once the car is going and the revs are up I can accelerate as hard as I want with no issues.
The flex disk and center bearing are new BMW parts, mechanics say the transmission and diff are ok, driveshaft has new u-joints and recently balanced.....
Any ideas at all would be appreciated.
PS: the person who mentioned this site today asked me to check if the mounting area of the center bearing is still solid.

Thanks in advance for any info.

I had this issue with my E46 a while back, and all I had to do was change the propshaft bearing.

Was your noise anything like this? (listen closely at about 2 seconds). I only had it when accelerating hard. Excuse the poor quality, recorded with my iPhone.

Hope you come right.

Can not really hear much, he rattle only happens on takeoff and if a certain amount of acelleraton there is a banging. I just took the drive shaft in to get the center u-joint replaced ( the mechanic says it is a little loose but the driveshaft rebuild place does not think it is the issue )
I can floor the car once I am driving about 30 kpm and all is good, when I go 200 kpm the car runs smooth.
Just seems like that if there is load at low rpm this issue happens.

Check that the centre bearing has been properly pre-loaded when fitted.

I hope you get to the problem sorted because I'm experiencing the very same rattle on my E46 325i Touring.

Yesterday I took my car to another mechanic is a different town and he claims that the center u-joint is faulty ( 2 others said u-joints were good ). I am getting the u-joint replaced and it will be done by July 2. From the suggestion above I will make sure to mention about loading the center bearing.

Update: Had the center u-joint replaced and driveshaft balanced, told the mechanic the proper steps to install it ( advice came from driveshaft rebuild place ) and all is good. Kind of pissed because last year a different mechanic had me replace the end u-joint and said not to bother with the inside one as it is good, when I still had a slight wobble at takeoff he said it was something else but could not figure it out.

There is a machine shop east of Montreal Canada, they replaced the end one last year and did a good job, should have had him do both but I listened to a mechanic that was wrong.
Are you in Canada?

Nope... very far from there in warm and sunny South Africa (which is where I thought you were)

Sorry did not make it more clear, I only stated it in my introduction.... I heard from people I was discussing my problems with that this is the site to get useful info from.
