I need new spicers to the driveshaft of my car. When I accelerate there is shaking coming from the drivetrain area. I've replaced alot of bushings so guess this is all that's left out.
It's an '89 GTA with 305 TPI (LB9) and manual transmission. I already got a pair of spicers from the shop but after measuring the old ones they seem to be too big. So what is the correct model spicers to get to my car? What should I for example look for on ebay?
Also, does the shaft have to be balanced afterwords?

 

Is your driveshaft steel or aluminum? 9 bolt or 10 bolt rear?

 

did it ever come with aluminium? It's stock. And it's a borg warner 9 bolt rear and t-5.

 

yes some did come with aluminum

 

how can i tell which is which?

 

you can tell by getting under your car and looking

 

If i had to guess I'd say steel but I can't tell for sure.

 

If a magnet sticks to it, it's steel. If it doesn't stick, it's aluminum.

The steel and aluminum shafts have different yokes and take different U joints.

 

Thanx! Good idéa. I'll try that soon.

 

I haven't had the chanse to check yet, but does anyone know the type of spicer that should fit steel or the aluminium type?

 

Okay, now I've checked weather it's a steel or aluminium shaft. Magnets stick to it so steel.
Does anyone know what spicer fits?
I'm attaching a pic of the spicer I got from a mechanic which seem to be too big.

 

That's the right one for a stock steel driveshaft.

 

The new spicers look very different from the old ones. Will they actually fit? Can someone explain how the front spicer is fitted? Is it just with four clips? Or how do I remove it? And do I have to balance the shaft afterwards?

Here's a pic of the spicer u-joint on my car now.
