PLEASE HELP. I'm completely lost at this point. While driving my traction control will randomly go off pulsating the brakes quite violently after replacing the entire rear subframe and differential. I have replaced both rear wheel speed sensors and the issue is still there. I have also filled the brake fluid reservoir as high as it can go, so that's not the problem.
I also realized it only goes off when I turn to the left. Doesn't care if I turn to the right, but if I turn to the left at all it'll start freaking out.
2010 G37X Sedan, I think its a Journey.
I have also used a scanner to read all of the wheel speed sensors and they are all reading correctly, even when turning. Oh, and completely unrelated, one of the A/C lines just *popped* out of the condenser, and released all of the R134a.

 

was the rear diff also out of a g37? the diff wasn't from a 350z/g35 by chance was it? The ring tone gear has a different teeth count than the g37/370.

 

How good are your tires?
have you double checked all your suspension components?

 

The most important question of all.

If it was just a subframe swap, you are missing an alignment sir. No matter what you do it will still do it. Improper alignment will cause drag/slip on one tire throwing it off, triggering the ABS.
