whirring/clunking from tailshaft..

Chris 83JA · Post by **Chris 83JA** » Tue Jul 20, 2004 11:21 pm

i get a whirring clunking noise from somewhere under my car. It's varies with the speed of the car, not with the gear, and it's the same whether my gearbox or clutch is in neutral or not. I don't think it's far back enough to be the diff, so i'm guessing the tailshafts the culprit.

I might change the uni's/joints if i can do it myself (to save the cash), anyone know part numbers? Is it a do-it-yourself job? It's probably worth doing them anyway, even if they aren't the cause, because there's a bit of slack in the drivetrain anyway

thanks for all help,

Chris

I had some strange creaking and scraping noises coming from under my car. It didn't sound like uni joints, but I jacked up the rear wheels and spun wheels, tailshaft etc. Because the tailshaft is hollow, you do get an audio illusion - the sound appeared to be coming from the centre of tailshaft, but no cracks, etc to be seen. So I pulled the tailshaft off, and found one UJ pretty well siezed and the other not far off.

I'm afraid it's not a DIY job (could be wrong - anybody done it before?). I had to take mine to a drivetrain & balancing place - not cheap, cost me 200 snappers to have the UJs replaced. At least the uni joints they fitted had grease nipples, though. And they gave it a nice fresh coat of black paint :)

If you have a decent vice it's pretty easy to do yourself.

That is provided they aren't staked in from factory (as opposed to circlip). Can someone confirm?

200 bucks doesn't sound too bad. So I just have to take out the tailshaft and take it to a drivetrain joint then?

Check your wheel bearings too - they can make quite a noise, but usually don't clunk.

Yep. Make sure that you get the rear of the car up as high as you can before you take the tailshaft out (so you don't lose your gearbox oil). I back mine up onto ramps and jack one rear wheel off the ramp so I can turn the tailshaft to get to the bolts.

Hardy Spicer seem to be a pretty good and reliable mob - they do tailshafts & balancing, and I think they're in most states. Otherwise try 'Balancing Services' in the Yellow Pages.

Chock those front wheels people! Dont wanna hear about a starion owner found ravaged to death by wild dogs while trapped under his car.

If you wanna get your tailshaft balanced properly and get uni joints fitted there's a place in Dandenong called GJ drivelines, ph 97063166.
I got them to remake my tailshaft cos my front yoke was bent when i broke my uni. They did it for about 90 bucks, and add about 30 bucks for the uni joint it doesnt cost much (including balancing).

But there should be plenty of service centres that can balance a tailshaft for you. And pretty much anywhere that has a press can fit the uni joint for you. It's a bit tricky to do it yourself, cos u need to make sure its straight when it goes in.
I reckon u should be up for about 50 - 80 bucks.

Yeh? It pays to shop around.
I got a nice coat of black paint too :P (well not me, the tailshaft)
i think it was 98 bucks to cut off the old yoke, weld on one from a holden, fit the unijoint, balanced and painted.
Cost me about 30 bucks for the uni joint itself.

Interesting - so the yoke from a holden fits the splines on a Starion gearbox? Is there a particular type of Holden yoke which fits?

Hehe i seem to be misleading you a bit

I have a supra gearbox, and hence a custom tailshaft. I have a holden yoke on the front because it's probably the most common and easiest to get uni joints for. I'm not sure if the spline is from a holden too, or if the yoke/spline is a bit of a hybrid.

But yeh it shouldnt cost too much to get a uni joint fitted.

:glare: ... it's surprising what difference a few trivial details (like different gearbox, engine, etc) make, isn't it? :)
