Good point, the first thing I did was look at the vacuum control to see if I missed or unplugged something.
The left front has the abs sensor on it. The difference between the advance and the dealer is the clips are slightly different and the dealer sensor has an +/- symbols on the inside of the connector where the advance does not.

My right front wheel bearing does not has a abs sensor, 4 wheel drive maybe??

 

Both my front wheel bearings have abs sensors. 06 Mega Cab 4x4. How else would the system know if your right front wheel was locked up?

 

LarryFrank,

It depends what year and model your Ram is. For the 1500 models, if it has the RWAL ABS system there will be one ABS sensor. If it is not RWAL there will be 2 sensors on the front and one on the rear. The newer models have them on all 4 wheels.

If you are wondering specifically what your Ram came equipped with from factory, feel free to PM me your VIN#.

 

I have a 1998 ram 1500 sport that the cruise quit working and cant figure out y. Cruise lights up on dash but doesn't engage. Y?

 

well you are in the wrong section but 9/10 times it is either a vacuum leak or a brake pedal switch problem.
