I have my new (to me) car in the shop for the mother of all gear whines, but the guys at the shop say they haven't figured out how to get the carrier out. They say it's not an OEM setup. Does anyone know if this is true (see pics)? Maybe a newb question, I apologize in advance.

It is an OEM setup,unless the gears(ratio) have been changed. It is a Torsen 'posi' used from 99-02 in place of the Auburns(what the mechanics are probably familiar with) used up to 1998.
The center block(commonly reffered to as a 'paddle') pulls out and since the bolt/screw is already removed,the paddle should just pull out. In picture 3,there seems to be some sort of 'shim stock' sticking out. What is that ?
The Torsen carrier in picture,because of its' short cap(the 6 bolts on the left side)appears to be a 2 series carrier used for 2.73 and 3.08 gearsets. If the gears have been changed to 4.10s',the paddle might have been had to be forced/hammered in resulting in great difficulty removing it. Get the ratio off of the ring gear,2 numbers indicating number of pinion teeth and number of ring gear teeth.
Once the paddle is out,the axles are pushed in to remove the c-clips and then the axles pull out. The carrier then come out in the normal fashion.

^^ what he said. Id probably take it somewhere else if they cant figure out this simple task.

Thanks guys. This is an M6. I have the SLP birth sheet with 3.42 ratio, so the car came with a 3 series carrier. It's disappointing to find that someone changed it to a 2 series. Why would they do that? It does have a 4.10. The previous owner indicated that it had been changed, but did not say anything about the carrier itself. I can also tell from driving it that it is a 4.10 for sure (speedo deviates negatively). I suspected it was a 2 series since it has the thick ring gear. What would you suggest? Should I be hunting down a 3 series carrier? I can't run a 3.08 in this car, 6th would be useless. I'll assume they can't get it out because it was forced in. Unfortunately I have no one else to take it to at this moment since I like in nowhere Mississippi and no one else does rear-end work.

Before tearing it down, they should do a contact pattern check as well as measure the backlash, then go from there. I wouldn't worry about what series carrier it is, as long as you can get the correct gears for it. A slide hammer with a hook rigged on it should get that paddle out pretty easily.

when you eventually get the carrier out,measurements will determine which carrier series it is. even though the pic is for auburn,it also applies to Torsen.



if it turns out to be a 2 series,3.42s',3.73s',4.10s' are available for it.

He's got the "thick" ring gear, so he def has a 2 series oem Zexel Torsen.

i thought i remember reading/hearing way back something about not being able to fit 4.10's or 4.11's in the 10-bolt axle having the torsen series 3 carrier. and it was something to do with the paddle block.
and there were some hack ways around it, maybe it was fitting it using the series 2 carrier. pretty sure it was somewhere on here i heard it, i basically remember you can't go higher than the 4.10 gear set in the 10-bolt because they don't fit.

Bet some jackass didn't grind the paddle enough and tapped it in place. I would hook some wire through it, then to a screwdriver and yank the hell out of it. No other choice really.

I always thought that only applied if the car initially came with a 2-series carrier. It's been a very long time since I looked into that stuff, though.

I had 4.56s in my 10bolt. They must have bashed it in with a hammer and put the wrong series gears on it. I had the zexel without the abs ring, whichever series that is, and they had the other series gears on it.

The ABS ring means that its a 3 channel ABS car (ie no traction control), has nothing to do with the series of carrier. The 2 series moves the ring gear farther from the pinion because in smaller numerical ratios the pinion is much larger because it has more teeth. The 3 series moves the ring gear closer to the pinion because high numerical gear ratios have less teeth on the pinion making it smaller.
