SO, my car has been a mess of half-assed things done to it (before i got it) and one of them is the rear end.

The previous owner swapped out the original 95 rear end, for a 2000 Camaro SS Rear end (3.73)

Problem being that the original housing reads the ABS from the ring inside the housing.

the Torsen rear-end does not accomodate this.

Does anyone know if i can hook up a wheel sensor to the existing wire??

And if so, which sensor would be compatible?

Any help would be greatly appreciated


I hate dealing with ABS when its not working....

A torsen rear will work if it is a 3 channel with the sensor in the middle. I don't know if you can rig one wheel sensor to make it work. My inclination is to say it won't.

Yep I think you need a 3 channel rear end, the one you have will not work with your abs set up.

Re: ABS problem Swapping in Torsen Rear-end
well

after having a look at the rear end and taking it apart to change the pinion seal

I have found that it has a sensor plugged into the top of the housing

however there is no ABS ring inside the housing for it to read, doesn't it need one?

Also the Sensor was COVERED in filings, so i cleaned it up and put it back in

This is exactly what my housing looks like:





Here is what the sensor looks like that i pulled out and cleaned:





I just wanna get the ABS working, or I will pull the bulb out while I have the dash out

I have no idea about ABS on these cars, there is very little on the net


Any idea how many ABS sensors a 1995 Camaro originally has in the rear? and where?

Thanks for your help!!

Do you have a V6 or V8 LT1 ?
1995 was the year Traction Control started as an option on the Z28 only,not available on V6 models.
The rearend picture appears to be a non-posi rearend,a carrier with springs between the spider gear set would be an Auburn limited slip, a carrier without springs(as in pic)is a non-posi open rearend. A Torsen carrier would have a 'worm gear set' visible in the open holes of the carrier. The carrier in the pic is not machined to accept/mount an ABS reluctor ring. A pic of what you ACTUALLY have would help.

This shows you the reluctor gear:

Injuneer, that is exactly what my rear end looks like, minus the reluctor gear.


I also ran the numbers on the torsen mechanism, it was made in May of 2002, and it is a 9022 which is supposed to be a factory 3.73 (which it is)


It seems to not have the reluctor gear, is it possible to put wheel speed sensors on it instead?

im not sure which year they changed to wheel speed sensors, and if or when the rear axle housing changed


this is EXACTLY what mine looks like (my previous picture was wrong...:P my bad, sorry)

mine has the sensor in the top of the housing, so im guessing they swapped the innards, and left the housing the same

Maybe the guts were swapped out, but the ABS sensor in the middle of the housing is not going to work without a reluctor behind the ring gear.

since 1995,both ABS 3 channel and ABS & Traction Control 4 channel were available. ABS was standard and ABS & TC was an option.
A 2000 rearend would have a Torsen but the 3.73s' were swapped in as they were not available from factory.
Nevertheless,no ABS ring on the carrier could have been left off by someone who didn't care about the ABS working.
No,wheel speed sensors cannot be tied into your ABS system as it's a totally different system.
You need to put a ABS ring on the carrier for ABS to be functional and ,unfortunately the ring(s) are no longer available from GM/dealers. They do show up occassionally/rarely on the for sale forums.
