i just put a moser 12 bolt in and i keep throwing abs codes. i'll be driving and the low traction light kicks in then after awhile the abs inop lightsup. i changed bothe rear abs sensors but it keeps happening. i'm convinced it's something to do with the rear but i don't know what. the rear originally was set up for a three channel (with the center ring gear) but is now used on my four channel, could this have something to do with it.
any help would be great it's driving me nuts

If it was set up for a 3 channel then that could be the problem. I have no issues with mine at all.

i hooked the car up to the abs scanner and the right side is showing 3 miles an hour slower then the left after 25 miles per hour.could the posi be binding up the one side making this happen. the sensors are new and i took a look at the tone rings everything looks fine. alittle more info that might help. i was driving around 55-60 miles per hour as soon as i shifted into 6th the car felt like it pulled back. almost like soething bound up, when i pulled the cover on the rear everything looked fine, the redline i put in looked alittle discolored for only 300 miles. but its a carbin fiber posi unit, so i dissimmed it as breakin dust from the unit . does this all make sense. could this rear be screwed up

everything ive read has said you can NOT interchange a three channel with a four channel without losing or having abs problems. hope im wrong but try a search

Check tire pressures... or anything else that would make one tire larger than the other (is one tire more worn than the other, did you recently get wheels and maybe a narrower wheel got mixed in with your wheels?) The posi binding would not cause speed differential.

I know what it is!!!!!!!!!!!

count the teeth on each of the reluctor rings on each of the axles i bet you one has more teeth thasn the other.

if the tooth count is the same for them both take a couple washers and space the wheel sensor that reads different then the rest, sometimes the wheel studs mess with the sensors. If that fixes it you can make a nicer spacer..

Also make sure one reluctor wheel isnt running out a whole bunch..

What is the code it is throwing?
Excessive wheel speed variance?

Yeh That Is The Code It Is Throwing. The Weird Thing Is I Ant Clear Them Out. When I Try The Scanner Is Telling Me To Turn The Car Off With Ignition On,but The Car Is Already Off. Some Reason The Scanner Is Picking Up 300 Rpm When The Car Is Turned Off

I DON"T GET IT. so i tried the spacer trick you were talking about. now instead of throwing a low trac light over 25 mph it happens everytime i'm coming to a stop. every light i come to i hit the brakes and at about 5-0 mph the low trac light comes on and i feel the pulsing in the pedal.
