So, you need some tight nuts. Good catch.

Ok, to help someone in the future who may experience the same
weirdness I did with their antilock brakes. If you recall, I had the
antilock brakes pulsing the pedal up as I came to a slow speed stop. I
didn't have a dash light indication and after some discussion here I
cleaned and tested the sensors and found no problems. Following
other's advice I disconnected the brainbox for the antilock system and
all was good. That is until I went to have the front end aligned after
I replaced a tie rod end. Found one of my front wheels had a loose
bearing. Drove it home and pulled the tire to see how bad the bearing
was and found the split nut that holds the bearing had come loose and
the only thing keeping the nut from coming completely loose was the
grease cap!!! Pulled the bearing and inspected everything and found no
damage so I repacked it and put it back together. Considering the
close tolerances on the pickup for the brakes, I hooked it back up to
see what happened and lo and behold the brake problem went away.
Appearantly the looseness of the bearing caused the sensor to lose
signal under certain conditions yet function fine otherwise. Moral of
the story, if the antilock brakes start acting weird CHECK THE WHEEL
BEARINGS!! Right now, as in as soon as you notice the problem. It was
only dumb luck that kept that damned wheel from coming apart at 75 mph...
