Hi, Larry.
I didn't even think of the ABS possibility. Now that I think of it, it
seems like the pulsing is randem through the car, not the once per rev like
a warped rotor. I'll have to get it out on the road and check into this a
little further. Also, it does only seem to be noticed under moderate to
hard braking. How would I find out whether or not this car has ABS (83
300SD)? Do the wheels need to be removed to check/clean ABS sensors?
TIA,
