Many MFGR's with 2 piece drive shafts have Giubo's.

your not helping

Yea maybe I'll go to the yard this weekend and look for a 328 driveshaft

I was just under the new 2015 Mustang and noticed that their using the same rubber guibo
wth?

[JGood]

Why not just get an e36 m3/328i driveshaft? That's what I used for 10k miles before swapping to the 6 speed. Even with the 6 speed, I'm using a stock e30 shaft with a 540i flange welded on. 15k miles on that and counting, full of drag strip launches on 235's and more burnouts, clutch drops, power shifts, and other terrible things then I could count. They're plenty strong enough.

I was using a eta drive shaft with a 24v swap guibo
This was the most skechey part of my hold build and only thing that I bolted on with out building myself on this whole build. I took it for granted that someone else did there job.. I found my weak link an blew it up....

live and learn..

I think I'll take a page from the LS/5.0 guys an build a single drive shaft with dual u joints?

Wouldn't that mean you have to drop the rear to get the driveshaft out?

Or are you thinking of making some sort of adapter to ujoints

[The Dark Side of Will]

It looks like the center sleeves were not large enough in diameter to have a wide enough region of metal to metal contact for the full circumference of the holes in the driveshaft flange.

If there was the appropriate amount of metal-to-metal contact, then that guibo should not have been any more prone to that failure mode than the stock guibo.

It looks to me that it's not the formulation of the urethane, it's the size of the steel center sleeves used.

You didn't overtorque the bolts, did you?

[Old city bimmer]

damn...that really can screw up a nice drive.

[Tjabo]

Crossing that damn thing off the list (Revshift guibo)... I thought the concept of it seemed a little funky already.

[delamaize]

I sprung for the garagistic shaft. We will see how it goes once I get to that point, and once I actually get the shaft....

[MonkeyMadness]

Holy shit... is that the revshift guibo?

Yes.. :(

Did the bolts break, or did they come loose? There's no reasonable amount of torque that should break those bolts.

I did a similar thing with my old e30 track car. Guibo exploded... Broke the driveshaft, transmission case, shift linkages, etc... Costly mistake.

Bolts broke... I have a feeling it has something to do with the poly inserts.
if you all remember I blew a center shaft bearing a while back. turned out i had the washers on the wrong side. SO i fixed it and noticed that Revshift changed there poly compound with out telling anybody...umm
didn't think to much of it... my bad

yikes ! what drive shaft are/were you using ? revshift big>small guibo ? ZF > E30 d'shaft?
did you kill the rear trans yoke?

ouch.

And this was the total carnage of the weekend.... :blowup:
