I just replaced this thing in October and have put 1,000 miles on the car and its totally ripped apart again... what gives. the rubber still looks brand new even

The M30 PULLLSSS man...

:rofl

Was it an OE flex disc?

my uroparts disc just did the same thing.. driveshaft wobbles now :-( time to get oe

I'm sure you followed Bentleys but just in case, there's a correct way and not so correct way to install them. There are arrow heads molded into the rubber on the outer perimeter that point to the respective yoke lugs that they bolt to. Also, it's important to put the bolt head directly on the metal guibo sleeve, hold it with a wrench so it doesn't spin and possibly twist loose the bond of the metal sleeve in the rubber, and only tighten the nut, which is on the metal yoke. Deviating from this (or doing burnouts in reverse if correctly installed) can contribute to rapid failure.

The guibo has 3 fat segments between sleeves and 3 thin segments between sleeves. When installed correctly, the fat segments will be compressed when (forward) torque is applied. They will shred and self destruct if clocked 1 hole off.

well . . that ^ and the driving style is the reason

i had the same thing happen to mae course i was flingin the car sideways around aturn but still.......either way it was replaced and i havent had a problem in i forget how many thousands of miles

lol. i put it on the right way but sure as hell didnt torque it down by just tightening the nuts. i did the opposite, held the nuts in place and torqued the bolt heads. so much quicker :)

it wasnt oem, it was a bma replacement. 1st place that can get me one by friday wins! ive got a calendar shoot to do!


should i grease the bolts when i put them in so they go in easier and are less likely to take out a sleeve?

^^^^ not as bad as mine...

No grease but use some Loctite on the nuts. Torque the piss out of the nuts too, I think the spec is 95 ft-lb. It's not easy getting them that tight. A prior mechanic tightened them too loose on my wife's e36 and eventually lost one of the bolts. It gives it a really bad vibration, kinda like a bad d/s center bearing only worse and over a longer speed range.

I'd say bimmerboy's shredded one wins.

95 isnt hard to do. But prolly is if you're underneath a car...

The arrows point to the bolts, right? That's what did. I had alot of resistance trying to get one bolt through.. I think that is my manufactoring defect. FYI: pictured guibo had 146k miles on it.. no vibration, just a clunk when I put it in drive. Amazing, huh?

What happens when it fails completely? Will the propshaft get dragged along the road and need to be replaced or nothing quite so drastic?

I don't like getting under the car, all I see is $$$$$ leaving my wallet

Guys - if you're replacing the guibo and its failing again... that means the driveshaft is moving out of spec... and that usually means the center bearing is turds. I always replace the center bearing with the guibo because its so easy. You should too.

you also need to make absolutely sure that the center bearing is directly centered to the centerline of the trans & rear-end or you'll burn them out in short order

besides, the vibrations and the clunking noises, it can destroy your engine wiring harness. it happened to me, after my guibo broke i kept driving with it being broken for a while and what happen was that the strings that are in the guibo caught the wires that went to the O2 sensors and ripped them out, causing them to short out, this short traveled all the way up to the ECU of my car. take a look for yourself..
