Would anyone be able to tell me, if a drive shaft from a 2.2 Omega will direct fit a 2.6 Omega. Or if there is any difference in the end splines, on the shaft that goes into the differential, or even shaft size. If not are the number of teeth for the speed sensor, on the inner CV the same?  I have a split inner CV boot on passenger side, on my 2.6. It was OK for MOT, so damaged it after. I thought I had got the correct boot, but it was too small in length. And am struggling to find the correct passenger side inner cv boot. But just found 2 good 2nd hand drive shafts, but both are off 2.2 omegas.

Thanks in advance for any help.

They should be interchangeable

Thats great. The parts person at vauxhall checked. And said there was two types of cv, but a complete drive shaft from a 2.2 should fit, with no problems from the teeth for the sensor, being different and the splines going into the diff are the same. So thought best check on here as there are knowledgeable, people on here.

I have been out and took measurements, to see if can find a boot off another car.  Measurements are, cv side 63mm, length to the smaller end of the boot 110mm, small end of shaft 28mm. Still cann't find one, plenty of outer cvs, with boots attached.

Thanks again.

They should be interchangeable 

If you refer to the parts parts catalogue, there are different part numbers for the various engine sizes, as well as different part numbers for the different manufacturer of the drive shafts.
If there was no difference, then the part numbers would be the same.
They may be interchangeable in theory, but I would try to get replacements off a like for like model - there's no guarantee they haven't been changed, but I think it's unlikely. I've never had to change a drive shaft on any of mine, and there is little reference from OOfers having done so on here.

[Doctor Gollum]

I wouldn't use the shafts off a 2.0 8v on a 3.2 used for towing.

There isn't a huge difference between the torque figures of the petrol 2.2 and the 2.5/2.6 so, for the purpose of the exercise, they will be fine.

If they're from the 2.2 diesel, that has as much torque as the 3.2 so, again, not an issue.

The rear half of the propshaft is interchangeable as well, but the front half varies according to engine AND gearbox types.

The different part numbers for the various engines will be due to the possibility of different shaft diameters, but will also vary if you're talking just the shaft or the entire assembly with CVs.

As for the different part manufacturers, then you can reasonably expect different part numbers from each supplier.

It used to be possible to buy CV boot kits for the inner and outer CVs, (they're different), and from memory, you pull the drives haft, break down the outer CV/boot to service the inner one first and then service the outer.

It’s possible that the boot kit you have is the opposite end to the one required.

Thanks everyone for the information.

Here are the links to the 2 drive shafts, I have been looking at.

This link sounds more promising the person says they will fit a V6

[Doctor Gollum]

The bottom link will be fine. I suspect they're the diesel ones

[addy]

Thanks DG. It probably is a stupid question, but is there a difference in length of drive shafts. From passenger side and driver side, or are the shafts the same length, no matter what side?

[johnnydog]

Yes, that's correct re the diesel driveshafts.
The 2.5/2.6 and 3.0/3.2 used part nos 90512928 and 90512925 depending on the manufacturer.
The 2.0 and 2.2 diesel used part nos 90512925 and 93170236 again manufacturer dependent.
The 2.5 diesel used 90512928.
So there was a degree of cross applications between the models. But you won't go far wrong fitting 90512928 or 90512925.

That I don't know, I have only removed, replaced the boots and refitted one side at a time.

I think they aren't sided.

Worst case you could always swap the CV and boot from the new one on to your existing one

Re your pm,. You're welcome

[countrywoman]

They are handed, good few inches in length difference.

[Doctor Gollum]

Even so, the CVs and boots will be useful regardless of the shaft length.

After all, the problem was a failed CV boot.

[addy]

Thanks to Omegod, who I bought the DTI drive shafts off. They arrived today, well packaged and protected, the parcel woman struggled with the weight. Now I have only got to work out the lengths, so can fit correct one to passenger side.

Just realised I have another diff which still has the shafts in, pulled the shafts and both measure the same equal length 

[addy]

Thanks Omegod, for checking the two drive shafts you have.  I did a side by side check, with the old one and as you say. I couldn't see a difference in length, so have fitted one of them. I have torqued the 6 bolts to 50Nm just got to do the angle tightning.

No warning lights have come up, when moving it slowly back and forth in the drive. So hopefully all is well.
