on mine, you can feel that sucker working.

remember, it works ONLY while you are in 2wd. once you shift into 4wd, it is disabled.

also, check your prop valve level in the rear axle, it could out of "alignment" so your fronts are locking up without the rears ABS'ing...

also, it's only for the REAR wheels... not the fronts...
