My 3 series sucks, help.

[Clarkey]

Bit of an uber bump, but doom has struck today. Car has now developed a good old fashioned clunking in the driveline. It's particularly profound when coming on and off the throttle quickly at low rpm.
Anybody here want to tell me that it's only a silly little propshaft guibo that's causing this?

 

[acemastr]

Don't the diffs generally knock on these?

 

[Matt82]

ive read on a few boards about those guibos. sounds like one of those (is that what you needed to hear?)

 

[robnut]

Guibo, or the diff mount. I had both go at different times.

 

[InvaderGIR]

Guibo most likely, but check your wheel nuts too. Some turd slackened off mine on the 318iS and it felt like a knock in the prop. Scared me immensely when I checked the wheels nuts and found them to be at fault.

Could it have torn a control arm bush?
