The ratio is on a sticker on the near-side rear face of the back axle. You may need to clean underseal off, but it should be there.
There's some discussion on axle ratios on Brickboard, but may only apply to US models. I quote:

"Manual transmissions usually have a 3.31, which is too tall for an automatic. Automatics will have either a 3.73 or a 4.10. You can use either--I prefer the 3.73 for its better gas mileage and quieter cruising. An axle from an automatic in a manual transmission car will kill your gas mileage, give you fierce acceleration, and be noisy on the highway. 3.54 and 3.91 axles also exist, but seem to be relatively rare, found mostly in older cars."

"The year of the donor car is important too. There is a tone ring (toothed wheel) in the differential that sends a signal to the electronic speedometer and ABS (if equipped) There are at least two types of these. Cars up to 88 have a wheel with 96 teeth. 90 and later have 48. I think 89 is the same as the later cars (48 teeth) but I am not 100% sure of this. You must have the correct number of teeth for your car, or the speedometer will be WAY off, and the ABS will not work. Changing the wheel is more trouble than it's worth---better to get an axle with the correct type already installed.

There are also two types of parking brake mechanisms, early and late, but it's not difficult to swap those parts over to the replacement axle, if necessary."

All the best

Just for anyone who wants to know, my 2.3 auto had a 3.91 rear axle, the 2.3 turbo doner car has 3.54 and the similar age LPT turbo has a 3.73.
I'm using the 3.91 axle in my car now wit the ft turbo engine and manual box and acceleration in 2nd gear is very interesting. 70mph in 5th is about 3000rpm.

What was the 2.3 turbo donor...940 HPT?

My Dad's 940 LPT had a shorter overall ratio in 5th than a 740 Turbo (M46)...the seemingly 'Volvo standard' 2700rpm at 70...but the 740 was unusually low (2300-2400rpm at 70, or something like that?). The M90 setup we put in Ryan's 740 Turbo (I'm assuming 3.54:1) put the 70mph RPM back at 2700 or so.

Yes, 1995 HPT with an M90 box in it. The LPT I saw with a 3.71 was the one I got a replacement gearbox from, that was 1995 as well. I guess Volvo made allowances for the lower power by changing the ratio.

Just need to know if its still for sale, I understand someone else may have had it.

There is someone else who has asked about the axle. They want it if is an LSD, If its not and its a locking diff then you are welcome to it.

Unfortunately you will have to wait until the car goes to scrap before either of you can have it as I need it to be able to be moved until that happens. When the car is scrapped I will contact the people that have shown interest in the axle depending on which type it is.

Hope that's cool, cheers Steve

I'm almost complete certain it'll be 1041 / locker axle. As far as I'm aware, anything with an FT engine (whether B200 or B230) got a locker.

cheers
