: northstar drive shaft problems, probably damaged bearing

Hi All,

First things first. I'm from the Netherlands, my apologies for any language mistakes. If you don't understand what i mean, please ask, i'll try to explain a bit better.

My Problem:

I have an STS northstar 32V from 1993. Last few months I hear a ticking, hammering sound while driving the car. The first few months you could only hear it on a new road but now you can hear it all the time. It really hammers bigtime.

I immediately thought of problems with the drive shaft. So I went to the cadillac dealer nearby and they thought so too, so they ordered a new driveshaft. In the meantime we checked out underneath the car and we noticed some margin (space, around 1 cm up and down) when putting pressure on the drive shaft.

The cadillac dealer
removed the old driveshaft, but it was not damaged. It was absolutely ok. The homokinetic was intact as well. The only thing that's left is the bearing.

My question is: is it possible to remove this bearing without dismantling the gearbox. Is it difficult?

We would like to do this ourselves, because the dealer is too expensive. The car isn't worth $4000 and they are asking $1500 to fix this and replace the bearing.

Any help is appreciated.


Best Regards,
Francois Bezmalinovic

Which side?

Good English, by the way - better than some posters here in the US. Just wondering what the "homkinetic" is...

it's the right side.

sorry, didn't know how to translate homokineet in dutch. But here's a website with a picture of a "homokineet" : http://www.reneniemeijer.nl/weblog/13-4-2007.html

here is an example:

According to this website it's called constant velocity joint, cv joint

So the cv joint is not the problem.

From the dealer we received 2 pages with parts and numbers what the problem could be, but unfortunately i cannot upload these 2 pages until tomorrow.

Following the link and you can see a picture of what he is talking about - this is listed on eBay. This is located in the steering knuckle - where the axle goes through opposite the gearbox. These bearing can make a lot of noise when they are going bad. Hopefully this is your problem and you do not have to work on the gearbox.

ok now I see what he means by a hub bearing. This cannot be the problem. I know this bearing. I used to have this problem on my vw corrado vr6. Everytime i turn on the right you here a big hammering noise. And when the bearing is almost completely destroyed you hear the hammering even when you drive straight.

This cannot be the problem on the cad. These bearings have been changed 6 months ago on a service check.

We have to focus on the spot where the drive shaft connects to the gearbox. There's this inner bearing the dealer was talking about that makes that noise when broken. the drive shaft was removed and was in good condition. The same goes for the cv joint.

I'll try and scan those papers tomorrow and show you what the technician was talking about.

I hope you guys can help me out on this one. So far thanks for the answers and talk to you all tomorrow!

Theres no bearing around the passenger (or drivers side) drive shaft. They are bushings and they are right inside the oil seal where the CV joint fits into the transmission housing. The bushings are available for about 50 dollars for the entire set (I think there are 4 of them in the transmission). I don't know if you can pull the bushing out of the output shaft housing with it attached to the transmission or not, but on the passenger side you can remove the whole housing just by removing a few bolts (4 to 6) once the CV joint and shaft are out of the way so it shouldn't be that big of a deal. The drivers side is tougher. Of course you will also need new oil seals as well.

Hi guys,

it took a while but a garage opened things up and the problem is in the gearbox. There are some parts that need to be replaced. Here in the Netherlands the only option is, to buy the complete final drive (as it is called I think).

I attached a PDF with the parts we're talking about. Can you guys please look at it.I would like to know if I can order these parts separately somewhere in the US, or do I have the buy it as a whole.

We'll probably need the following numbers:

nr. 110 - 111 - 112.

Here in the Netherlands I have to buy the following as a whole:

from left to right part 112 to 132 and everything in between (the first page in the pdf). It costs about EUR 1100,00. This is almost $ 1265,00.

Can someone help me out, find an address?

Many thanks!!!!

I'd probably replace the entire transaxle as a unit. Search ebay, or google used parts/cadillac or such. You could probably replace the entire thing and have it shipped for the replacement parts total cost.

Hi Derone,

can you tell me what the numbers are for the entire transaxle?

Dalma

anyone who can help?

car is standing still. On the first page i attached a pdf document with the numbers i probably need.

I'm need sure if there's a company who selling the items seperately or if you can only buy it as a whole.
