Im getting a abs a break light on my 2000 dodge ram 1500 4x4 i just comes on when it feels like it i can just be driving down the road and it will come on ???????? is it a wheel sensor or somthing like that

 

It could be the sensor. If I hit a speed bump hard enough and just right I can get my ABS/Parking Brake lights to come up.

 

it is most likely one of the abs sensors. there are two in the front and one in the back, at least on my truck. it doesn't really cause a problem unless you mash the brakes. if you slam the brakes while one of these sensors is malfunctioning, the wheels will lock up.

 

Mine will come on randomly when the connections get dirty. Any time I get the truck good and dirty I have to crawl under the truck and disconnect the two connections right over the rear diff and spray them with contact cleaner. But after that they work fine... until I get it dirty again.

 

Check your fuses first, then check your front hubs and see if you have wires coming out of them from the back. If you don't see any wires you only have RWAB. And as stated above, try cleaning the connectors on top of the rear end housing before replacing the sensor.

If you do have wires on the front , check your hub bearings, because no amount of cleaning will fix the front as they are built into the hub/bearing assembly.
