E30 Driveshaft Vibration Problem

Recommended Posts

I forgot it has arrows <_<

It has 2 arrows, both going different ways? So if you flip it round it would be the same?

Or am i missing something?

The arrows must point to the flange arms, which should always be the nut side.

Yeah, There is no right or wrong way for the guibo.

incorrect.

excluding reverse you can imagine the driveshaft spinning in one direction ...

the guibo has 3 thick sections, each containing 2 bolt holes. If you imagine the gearbox output shaft pulling the drive shaft around in a circle, do you want it pulling via a thin section of the guibo, or a thick section? Although you may flip the guibo back to front you must line up the bolt holes correctly.

Really. I always thought it was the whole same all around and it didn't matter as either way the holes were in a triangle anyways. Sorry for the mis-information!

I stand corrected :mellow:

Right so, good morning this morning, got the exhaust and driveshaft back off.

- Got a new hanger bearing mount thanks to Ian (Hartage).

- Have checked the u-joints and they seem to be smooth as butter.

- My guibo should be entirely flat on both sides right? Cause it has a slight bend in the middle <_< probably from all the vibration.

- My only problem is I can't get the two halves of the driveshaft apart :( I usually have mates to help me, with a big pair of stilson grips or a big bench vice but I can't seem to have enuf grunt to get it off. Anyone got any tips? or should I leave it for someone to help me tension it.

Cheers, Nathan

I assume you have loosend the locking collar on the driveshaft?

And mark the splines when you take it off so it goes back together how it was.

^ Righty. Got it undone. Just required a big bench vice, stilsons and some scratches on the driveshaft, but hidden now with some satin black paint and sanding and filing ;)

So can put new bearing in.

Anyone have a answer to my guibo q'n? Please! :D

So when you removed the whateveritis, it left a gap in the driveline??

You did loosen the spline to take up the gap yes??

Can see how one of the 3 edges isn't sitting on the bench, like it has twisted.

And westy, yeah but the balancer is only 2mm think alloy...so I was thinking maybe adding a few washers. On many of the other forums I have looked at, they have removed without problems.

I think it now had nothing to do with this, it was probably the loose gearbox mount which flowed onto everything else breaking down the driveshaft.

It's bloody fixed!!!!!!!!!11111!!1

Massive ups to my Dad, who spotted it a mile away. I had three bolts going through the driveshaft flange, through the guibo straight onto the gearbox. Shouldve had another three bolts separating the load, hence making the damper work properly and taking out the vibration as opposed to having the driveshaft straight on the gearbox. I am a idiot. Never want to see another driveshaft again :( biggest n00b fail evar. Doesn't help that he undid that half of the car and I had no idea how it really looked when the balancer was on, oh well trap for young players. least it is driveable and skiddable now :P

Thanks to everyone for their input on this thread.
