2-wheel abs or 4-wheel abs?
well the other day my abs light and brake light came on followed by my speedo not working. well i looked it up and have narrowed it down to either the abs sensor on the rear diff or the speed sensor on the tranny tail housing.
anyways the abs sensor is first and autozone has one for a 2-wheel anti-lock breaks for $35 and one for 4-wheel anti-lock brakes for $46 which one should i get? is there a way to find out if i have 2 or 4 wheel anti-lock brakes?
thanks guys

I have a 98 Ram 1500 and it has rear ABS only.
To see if you have four wheel ABS, the easiest way is to look at the back side of the front wheel. If there is just a brake hose, NO front ABS.
Is there is a brake hose and a wire then you have four wheel ABS.
My ABS and brake light are on and my speedo is working fine.
I'm gonna change the ABS sensor.

ok so i was underneath my truck earlier and cannot find out where the vehicle speed sensor is located.
my haynes says it would be on the end of the tranny on 2wd and the end of the tcase on 4wd.
well i search all over the tcase and i dont see any sensors that resemble this one. did autozone just get me for $35 or am i blind?
i think i might just bring it back and buy some rear end lube. <--- that just sounds really funny, but cant think of anything else to call it right now.

I can't say exactly where the sensor is, but I'm headed outside now and I'll have a look on mine...

I went out and had a look, but the only wires I could find are on the tailshaft of the trans, but I think they are for the OD unit. Nothing on the transfer case that I could find other than the vacuum lines. So I opened up the 01 Service Manual and found this:
So I went out and had a look at my rearend and it has a sensor on it so I assume this is the VSS? Dunno what year Dodge decided to go this way so I can't say much, but have a look there at least and see if it's unhooked or has broken wires first...
Gas Engines and/or Diesel With Automatic Trans.
The Vehicle Speed Sensor (VSS) is no longer used
for any Dodge Truck.
Vehicle speed and distance covered are measured by
the Rear Wheel Speed Sensor. The sensor is mounted
to the rear axle. A signal is sent from this sensor to the
Controller Antilock Brake(CAB) computer. A signal is
then sent from the CAB to the Powertrain Control
Module (PCM) to determine vehicle speed and distance
covered. The PCM will then determine strategies for
speed control system operation.
