ABS Kicks in at low speeds

Hello!

I just replaced the L and R transaxles, due to split outboard CV boots.
(Research said it was easier and quicker to just replace the whole
axles than to replace and repack the boots and rebuild the
transaxles.)

The parts that I obtained were from autopartswarehouse.com.

Installation went well, but after assembly, the ABS system kicks in
and pulses the brakes at slow speeds--almost when coming to a stop.
Upon inspection, it appears that the ABS sensor(s) are not lining up
correctly on the pulser rings on the CV axles. It appears that the
outboard portion of the axle should be "sucked in" about 1/4" more
into the hub, so that the sensor will line up correctly on the pulser
ring. As it is now, the sensor is just barely riding above the inside
of the pulser ring, and I suspect that this improper mating is
activating the ABS.

The spindle nut is properly torqued, and it appears that the axle is
being pulled tight against the hub--in other words, there doesn't
appear to be another 1/4" to tighten up anywhere so that the pulser
and sensor line up correctly.

Does anyone have any experience with this? Am I missing something on
the installation that is prevening proper alignment of sensor and
pulser ring? Or are the transaxle parts that I ordered just machined
improperly or the wrong parts for this installation?

I appreciate any help you might be able to provide.
