Hey guys i have been looking at a 02 2500 4x4. The current owner said it has a abs light and it was the wheel speed sensor. How can i check this or determine which one wat is the price of the part.
how hard is the install and could it be somthin else major

 

my first car had/has all wheel ABS and always has the ABS light on. so one day i decided to "test"( have a little fun at the same time) and punched the gas to about 35mph and then slamed on the brakes, found out that the passenger side front was locking up. here i am 4 years later and haven't bothered to find out whats broke on it. my luck would make it be the ABS module (early ABS gotta love it)

 

You can get a speed sensor for about $30 at dodge and its easy to change. Its on top of the rearend housing. My ABS light came on and a new speed sensor fixed it. If nothing else buy one and take it with you when you look at the truck and put it in before the test drive. It would be better than buying a truck and it needing a whole bunch of work. You will probably have to disconnect both batteries to reset the computer.

 

Check the resistance at the ABS Controller on the driver's side above the engine fuse box. Disconnect the big coupler and check the resistance of the farthest right hand pair (should be 1800 ohms). Pull off the right smaller connector and check both pairs of top and bottom wires (should be around 1100 ohms). Zero ohms on either one show a bad sensor or open circuit. Left and right speed sensors are exactly the same part number....

 

Just recieved a answer to check your vaccum hoses they crack and break,if you have low vaccum they will come on and cruise will not work either! The ones under the battery at the cruise acuator are prone to failure! I will be checking that out Monday AM. I have the same problem!
