Tech Note 1: Anti-Lock Brakes
1989-2002 Dodge Ram 3/4 ton and 1 ton trucks and many newer Ford vans are equipped are equipped with anti-lock brakes. Both rear wheel and four-wheel anti-lock brake systems use the same rear axle sensor components. In addition to providing a signal for brake control, the system is also used to generate a signal for the speedometer on later production models. The rear axle ABS system used on these vehicles is rather crude by today's standards. The signal is generated by a toothed steel tone ring pressed on the differential case next to the ring gear. A magnetic pickup is located in the top of the axle housing above the tone ring. Since the unit is sensing differential speed and not the speed of either rear wheel, it can not be used to selectively apply the individual rear brakes. The tone rings are not a wear item and usually only need to be replaced when there has been a catastrophic failure of the gear set or differential.

Tech Note 2: Heating
Like a flywheel ring gear, your new ABS Tone Ring must be heated enough to expand the ring so it will fit on the diff case before it cools to a shrink fit. A heat gun is preferred over a torch as excessive heat can damage the Tone Ring!
