Torque Tube \ Drive Shaft Coupler Question
When you rebuild these couplers, are you all going with OEM style or aftermarket? Poly? Rubber? Billet? Any why.
This is a ROAD RACE application, and not for 1/4 mile ever on my manual transmission.
thanks.

I've never rebuilt one, as there are too many things that can fail, and it's pretty much impossible to determine if the shaft has issues, or if it's a bearing, or a donut etc.
In my personal experience using new one, but stock and modified with an aluminum donut, I never had any increase in longevity with aluminum, and personally think it adds a lot of shock to the drivetrain.

You can get a FEBI coupler or the Lemforder which is the OEM. I went with the FEBI. I got them at: http://www.bmwpartsexperts.com/ They were about $50 each.

We deal with these damn things all the time. Our thoughts are
Stock shaft use two new rubber GM or BMW parts
Carbon shafts run rubber up front and solid in the rear.
Make sure the shaft isn't bent, there is a large plastic wear indicator in there to look at closely.
Heat up the bolts and they will come out nicely. Don't heat up the bolts and you will be breaking tools.
The large snap ring can hurt you, so make sure Tony has a big enough snap ring pillars. If not I just bought the shop a new one that you can use for a few days.

I have replaced bushings with BMW parts and aluminum couplers. As David says check the rest of the TT carefully. I have had several that beat the bearing seat out at the flywheel end.

Hey Zenak,
If you want to rebuild one before you take the car apart I have a torque tube in good shape for sale.
$500 +shipping.

Bad link, but such great info it was easy to google and shop around, thanks again. $110 shipped for 2 couplers is a great deal. Im not going to do the full rebuild I think. But new couplers is always a god idea when matching up a hodge podge of parts so it all fits up snugglie tight

Normally there is a noise that comes from the tube if a bearing is shot. The rubbers fly apart in a bad way. The idea is to get to it before it becomes a major problem.

What does the noise sound like? I have always heard a slight rattling noise when in neutral/clutch out in almost every c5 I have driven, does the noise just get really obnoxious when its time to rebuild?

i got the BMW version ones with the metal bolt sleeves in them. With Shipping after shopping around by part# it was $117 ground shipped. Im just doing the rubbers, the bearings tend to be good even under harsh conditions for some time. But form the people I spoke with its a good idea when even you are pairing up a new set of parts to change out the rubber couplers if they show any signs of wear at all, since as Randy put it they can fail in a jiff and that is bad. There are 2 kinds of BMW ones, one which is all rubber, and one with the metal bolt sleeves, for the HP/trq that vettes put out I would not suggest the cheaper ones without the sleeves.

Keith, make sure when you install them you get the orientation correct... there are arrows showing which way to mount them. I forget whether you want them facing forward or backwards. when I did mine I installed an aluminum coupler in the rear and a new BMW rubber bushing in the front one. No issue so far with either.

by the time you hear a noise the TT is usually toast in my sad experience.
