I see this too often

crap.
Now I am worried. I am positive I did it right, but I'm worried. Do 2002's have the same markings?

No worries on the '02, giubo is symmetrical.

I just got one for my five speed swap, it came with an instilation guide.
Here is the PDF for it. I was a little unsure how to put it in till I saw this.

Real OEM has issues. it also says that the 325i needs a 96mm flex disk, when really it is a 78mm disk

that's because it depends on the date of manufacturing. some do use the larger flex disks.

also, the ETK shows the proper orientation of them. I've put one in backwards by mistake - it was dead in less than 200 miles.

finally, beware of cheap Chinese clones. Real BMW parts do not have gigantic MADE IN GERMANY marks spray painted on the sides..

i hate doing the guibo but now i think i should check it.

Lots of confused people here.

There is a three bolt flange on the trans and also on the driveshaft. With the giubo in between them, make sure the arrows pointing toward the driveshaft line up with the driveshaft flange ears and the arrows pointing towards the trans line up with the trans flange ears.

See how the giubo is not even all the way around? In between the bolt holes it thick, then thin, then thick, etc.

What you are doing is putting the thick sections in compression during acceleration as the trans flange twists the driveshaft.

good post.

Damn, now I need to look to make sure.. it's been a few thousand miles. This applies to the E36 giubos as well for swaps (also wow - never knew about the spelling and pronunciation of "jew-bo" based on its Italian designer).

I suppose the reasoning is that the rubber is beefed up in a pattern (looking above) to better support the loading from the trans bolts pulling against the driveshaft bolts in the driven direction.

I was looking at the nuts when I put one on wrong... As soon as i put everything back together, i realized the mistake and had to remove exhaust and all the other crap to go back in and correct it.
Don't even look at bolts or nuts; look only at the three points of tranny and three points of driveshaft.

What?

[mr.vang]

It had nothing to do with where the nuts are and everything to do with the arrows needing to be pointing to the flange, not away from it.

So, this? Everyone who is just throwing stuff out there is making it more confusing then it is.

I did mine and all 6 nuts were on the trans side, I could have slid the shaft out again and put the screws in before sliding it up all the way, but honestly I don't think it matters which side the nuts are on.

I was able to put a 17 on one side and a torque wrench on the other. Make sure those fuckers are tight, and if you re-use the lock nuts place them in a vice and squish the top ring a little bit to make it oval again.

having the 6 nuts on the trans side is correct. it makes it easier to change.
i've reused and never seen an issue with anyone reusing them.

PS i thought this may need to be bumped for the new people.

Actually, if you look it up, it's not guibo nor giubo ...

'Giubo' was what the guy who invented it named it, the generic term most manufacturers use is flex disc.

BMW's ETK has got to be one of the worst guides to refer to for parts names haha, likely because of translation issues.
