Car 1: 99 SS, SLP Y2Y Auburn, ASR, 4.10 gears Car 2: 99 Zed28, Torsen, no ASR, 3.42's
I'd like to swap the complete rear end from the SS into the Zed keeping the ASR functional in the SS. As I understand it there is a "reluctor" in the ASR rear. The question is:
Can the swap be done? How intrusive & technical a procedure is switching the reluctor over? Anything else I need to worry about?
TIA

From what I know the ASR cars are 4 channel ABS systems and the non ASR cars are 3 channel systems, that might cause a problem connection wise..
3 channel - ABS reluctor ring located in pumpkin, ABS only. 4 channel - ABS reluctor rings located on axles, ABS/TCS (ASR).
About the installation/removal I can't really help you out on that.. Sorry, I have yet to do that but I will be.. if I break something.. Posted by poSSum (Member # 119) on :
Thanks Curtis,
I think that pretty much rules out that swap. Time to line-up some 4.10's

As Curtis noted ASR equipped cars have 4-channel ABS, which means 4 sensors and 4 brake lines.
On ASR cars the ABS module contains both the ABS function and ASR function, and the wheel speed sensors are used by both systems. Lose one lose the other (if a code is thrown....been there). Hard/panic braking on this cars without ABS is......interesting. (Been there too)
On three channel systems the rear wheels or axle speed sensor is the reluctor in the pumpkin. On four channel systems the individual rear wheel speed sensors are reluctors mounted on the end of the axle shafts behind the wheel mounting plate/flange outboard of where the bearing runs on the axle (as I recall).
The other problem is the brake lines. On three channel syatems there is one brake line going to the rear axle and the brake fittings are normal AN (??) filltings. On four channel systems there are two brake lines going to the rear axle and the lines do not use normal fittings. They are a "bubble" style fitting and the fittings on one line are larger than the other. This makes it impossible to put the flexible lines on backwards thereby crossing up which brake line goes to which brake (would not be good with ABS ). BTW, I have not been able to source this style of fitting. I found the smaller size but not the bigger one.
So if you change the whole axle you still have to pull the axle shafts out to change the wheel reluctors for the four channel (ASR/ABS) system. You will also have to remove the brakes and lines from the axle and leave them on the correct car (this no big deal, and saves having to bleed brakes).
So no matter what, it looks like you are into the pumpkin. Seems to me it would be easier to just swap over the gears and differential.
As an aside, how have you corrected for the speedo reading with the 4:10s?? Prgramming or the SLP black box. That will have to move as well.
My two cents.

Thanks Bill.
Great info.
I'll leave the SS alone and look at gears and diff for the Zed. Torsen T2R is looking like the preferred unit right now.
