I have a 1998 Ram Sport 1500 5.2L 4x4 that has an intermittent ABS and Brake light on. It is getting to be more regular, once every 3-4 starts. Truck pulls slightly to the left when brakes are applied. I have changed the rear speed sensor but no difference. Speedometer works fine as does everything else. Since this is a 4x4 I believe it should have speed sensors on each of the front wheels as well but I cannot locate them nor any wires on the axle that would go to them. I have removed wheels, brake pads and still cannot find them. Help. Thanks Tom

 

There's only two speed sensors, the one you replaced and one on the trans. Is your truck 4 wheel abs? If so check the front hub/bearings for play. If it has play (and you have 4wal) that's likely the problem.

 

are you low on fluid ever?

 

Pulling to the right..and changed speed sensor?

Fix brake problem first. That may cure it.

 

If you don't see any wire's running to each front hub bearing assembly, you only have rear wheel anti lock. I'd check the brake line running along side the fuel tank first (hard to check), then pull the drums and see if a wheel cylinder is leaking. One side or the other not working on the rear can also create a pull.
