I've heard the stock rear diffs on the S197 Mustangs equipped with anti-lock brakes have a toothed rim around the circumference of the 'spindle' portion of the rear differential. I have not taken apart my rear axle (YET!

) so I cannot confirm this. The purpose for the toothed rim is to allow the ABS to work. I'm seeking to upgrade my rear axle to a Detroit TrueTrac unit. However, every Detroit TrueTrac I have seen the 'Spindle' on the axle has a smooth circumference, not toothed.

Does anyone know if the spindle on the 05+ S197 Mustangs equipped with ABSis toothed or smooth as shipped from the factory.
Has anyone who has swapped out the rear end for Auburn/Ford Racing/Detroit rear axle with a Smooth/untoothed spindle noticed that their ABS no longer works?

Thanks for the replies.

The ABS exciter rings are pressed onto the axles. You can change the differential carrier without affecting the ABS brakes. I put an Eaton posi in mine.
