Driveshaft knocking. Help***128553;

I have a 2000 bmw 323ci Manuel 5speed. Now when I take off in first there's this huuuge knocking clustering sound coming from underneath my cup holders and e brake. I know it's my driveshaft but I'm not sure whether it's the u joint or the support bearing. It's getting worse so I just have my car parked. Thanks..

I don't see a question in your post, so I will assume you are a person with down syndrome. What you do is get the car on the lift and remove the exhaust, remove the heat shield and inspect the driveshaft.

Well first of all calm down with your shit talking names. I don't want to be an pussy and talk shit to you over the internet. Second I just drove from Cali to Oklahoma so I have no tools to do that. I had my car towed to a shop and it's a loose driveshaft bearing.

So what is the point of posting in the forum then?

Sounds like more of a u joint problem if it's knocking hard... is it on acceleration or Deceleration.

Both. There's nothing holding my driveshaft the whole bearing broke off with nothing supporting it so the driveshaft just moves like crazy. Well was

When my bearing went bad it was the transmission mounts broken shifting the driveshaft sideways.

Trashed the u joint........lots of play
Csb.....shot.
Guibo......cracked
And last but not least......the cv axle at the end of the driveshaft was working.....but heavily bound up.

So.....when your csb goes......what does it take with it.
