A couple of large zip ties wrapped around it should buy you some time.

And this is why the forum is valuable!!  Thanks very much!

When they are ready to fail, they will give you plenty of warning with lots of driveshaft vibration.

Cracks? Meh.

If you WANT to do preventative maintenance, it's not rocket science. I've never done one on a BMW, but they are done all the time on E30's at the racetrack while laying on your back in the dirt.

Here's a "made in Germany" replacement on ebay

Here's a generic guibo replacement. It's basically going to be move all the stuff out of the way to give you access to the driveshaft, probably remove the carrier bolts to drop the driveshaft and loosen the bolts that holds the quibo to the driveshaft and the trans, pull out bolts, replace quibo, then reassembly is reverse order of disassembly. Not a countryman, but it'll give you an idea

So I just got the car back - 2012 Countryman All4 - from getting a new thermostat and water pump at the dealer.  While there, the service advisor advised me that the guibo (flex disk) was cracked - she said it was not an emergency situation but it should be replaced to the tune of ....wait for it.....$700.00!!   So could someone kindly educate me on this topic - I'm aware of the part but $700.00 seems like a crap load of money to replace it.  I just paid $1700+ for the thermostat and water pump and am feeling slightly sodomized by that!!    Any opinions are good opinions...thanks.  John
