I see this too often

Great information! Was unaware myself and I can see how this could cause multiple scratch your head moments if installed incorrectly over and over again.

Might as well add torque specs to the nuts in the post for added info.

Good stuff! This gives me inspiration to change my Giubo since it has not been done in approx 140 K miles. Might as well do the CSB at the same time I imagine.

Bottom line here, if you can't tell from the above pics whats right, probably best you don't do the job.

I'm just saying this to help alleviate future confusion. In your initial post you quote JinormousJ saying that the arrows always point towards a flange and never towards a nut, then you post one picture of an incorrectly installed guibo and one of a correctly installed one. On both the correct and incorrect installation the arrow is pointing towards a nut, it's just that on the correct installation it is pointing towards a flange and a nut. You should either remove the part about pointing at a nut altogether, or if that really is important you should find a picture of one where the arrows are not pointing to nuts at all.

Time to recheck...

I see

[JinormusJ]

There are 6 small arrow notches that alternate direction, meaning, if your looking at an arrow that points left, the next one will point right and vice versa.

That being said; the arrows ALWAYS point to a flange and NEVER points to a nut. Essentially, there are many ways of wording it, but the arrows will always point to the flange/bolt head and never toward the threaded end of the bold/nut. Guibos are offset so that they are reinforced on the side that touch metal; putting it in backwards means the reinforcement is on the other side and will cause premature guibo failure

[Cabriolet]

the giubo arrows alternate. so since the driveshaft and the transmission each have 3 flanges EACH flange gets an arrow pointing towards it. it's the little "V" on the giubo.

close. there are 6 arrows on the giubo. three point one way, three the other, alternating. all 6 flanges get an arrow pointing towards it. 3 on the transmission output and 3 on the driveshaft.

your not describing this too well. If there are arrows pointing opposite directions, then orientation should not matter. But it does. So there is something your leaving out.

Also pic with the guibo doesnt really show a difference where the flange should be

[Wh33lhop]

I dont get the difference between the right and wrong. They look like the exact same orientation. The arrows are pointing to the nuts on both pics.

You want the arrow pointing towards the flange that hole is connected to.

Brandon,

Arrow always points to metal, not the engine. You can instal a Guibo backwards if you follow the "towards the engine" rule

I know what you are hitting on. I did not word it right, those notches go on the drive shaft not on the output flange on the transmission. Not talking about flipping the disk over. I was talking about the arrow in the second picture down bolting to the output flange on the transmission.

The nuts are not what is important. The arrow points toward the side of the guibo which should meet with a flange at that point.

no, they are pointing in opposite direction.
