Clicking Sounds

[G3N3M3]

Hey Everyone...

I recently bought a 2004 coupe from a friend of mine and since the transfer, I've noticed a clicking sound coming from under the center console. The noise is only when the car is in motion and not during idle. Any ideas what this may be?

my guess is the guibo underneath is shot

What's a guibo?

Looked it up:

A giubo (/ˈdʒuːboʊ/ JOO-boh; etymology: giunto Boschi, "Boschi joint"), also known as a flex disc, and sometimes misspelled as guibo, is a flexible coupling used to transmit rotational torque between the drive shaft and the companion flange on mechanical devices, such as an automobile engine.

Hopefully it's nothing too serious. Made an appointment with the guys at The M Shop for later this week.

Thanks for the heads up!

Here's a more simple answer.

When your car is on a lift, look underneath where the transmission mounts and the driveshaft is. If yours has cracks or chunks missing then its time to replace it. This is what a normal guibo looks like.

You should also check the center support bearing which is not far from where the guibo is. If you replace your guibo you'll want to replace this as well.

Is this normally an expensive fix?

The actual center support bearing is not too expensive, but there is a fair bit of labor involved in getting to both that bearing and the guibo. Bottom plastic panels, front reinforcement plate, rear v brace, exhaust section 1, exhaust section 2 and heat shields all have to come off to get to the driveshaft. An afternoon's work, but not entirely sure what a shop would charge.

If you plan on tackling this yourself, be aware that both the CSB and the guibo have a certain orientation that they go in. This video talks about the guibo: https://www.youtube.com/watch?v=Vw7Zbp1rfGI
BMW calls for both the bolts and nuts on the guibo to be replaced. And don't forget to preload the CSB 4-6mm towards the front of the car before torquing.

Also, TIL that it's spelled giubo and not guibo.

^^ what he said. I just did this recently, and made sure to buy new nuts/bolts, exhaust hangers (mine were worn) and anything rusty if you live anywhere north you want to replace.

I also changed out all the giubo nuts & bolts with new. There is a proper orientation of the giubo too, if not it will lash

Wow thanks for all the info! I'm not much of an experienced mechanic so I'll see if the shop can tackle this at a reasonable cost. Good reference though, always looking to further my education on these cars!!

I'll be sure to bring it up to the guys at the shop...thanks!

While your mechanic is in there, it would be a good time to change out the transmission mounts. They’re literally above the giubo.

I use and recommend these https://www.rogueengineering.com/Rog...nts_p_137.html


Here’s a parts list you’ll need for the other stuff if you decide to order on your own. I listed OEM bc that’s what’s recommended. You could go with a Febi brand for about $100 less.

If you don’t have a mechanic you should try and reach out to this guy. His attention to detail is second to none! If I wasn’t in NY I would definitely let this guy work on my car.
