I have a 1996 dodge ram 4x4 1500. I am about to replace a wheel hub assembly on the front of the truck (passenger side) How can I tell if I need abs sensor....I didn't notice any sensors around the wheel, but I have an abs light in the dash can I find out by calling the dealership and giving them my vin? Or is there some obvious way that I just passed up.

 

If there are no speed sensor wires on the front hubs, you just have rear wheel abs. 4wal will have a fair sized motor/controller under the hood, rwal just has what looks like a proportioning valve with a couple solenoids on it.

 

+1 The ABS system will be contained in the engine bay on the rear driverside by the hood hinge. If it's empty there, then you don't have 4 wheel ABS. If you have something there, then you, more likely then not, have 4 wheel ABS.

 

You can tell if you have abs by doing a few situps.

You only have rw abs. That's the little connector sitting on top of the pumpkin back there.

 

count the number of hoses and wires going to your front steering knuckles. 1 is the brake hose. if you have a second wire/hose thing, then you have front abs.

 

when you're young you have abs that look like a 6-pack. after you get old they look more like a keg. i like using squirrels' icon...

 

Where's the crosshair?
