on my way home the brake and abs light came on...wheel sensor seem ok dont know how to check if its hooped or not...also would the abs hub cause the tire to wear funny??? i had the ball joints done and 3 wheel aliments done and its the one tire thats wearing funny...what a **** off cause they were new

 

Do you have 4 wheel ABS? Most of the problems are caused by the rear wheel speed sensor located on the rear diff. If you have 4 wheel ABS there is and additional sensor on each front wheel.

 

i have no idea its a 2000 dodge 3500 with disk up fron and drums on the rear..is there anyway to find out if the abs front hub is buggered???

 

I'm not sure what you're referring to as a "ABS front hub", but to check for ABS sensors on your front axle, look for a tone ring next to the inside of the front axle next to the brakes. There will be a wire running to a sensor that's located towards the top of the axle in that area.

 

oh sorry... i ment how to check for the front abs...how do you test each wheel to figure out what one it is?? also if the tone ring is out will that cause the light to come on?? i dont know how it would have got knocked out though as i was just driving down the road...my brake fluid was a little low so i topped it up could there be a air bubble in there? would that cause the abs light to come on?

 

I hate to do this to you but a member here a while ago posted a way he used to test his 4 wheel ABS. If you do a search I think the members name was Lary, you might find the post. I don't know how a tone ring could go bad, they're just a metal disk with slots cut into the edge. The only way to get the ABS system scanned reliably is at a dealership, and it's expensive but it will tell you exactly which part is bad and you can go from there. I'm still thinking it's the sensor on the rear diff. It's a dealer only part so check around for the best price.

 

no problem i called the dealer and they said if i have the senser in the center of the rear diff its a good chance i only have the rear abs..and i have the rear center one..i called lordco and they have one in stock 40 bucks...the dealer wanted 68 and it was accross the country...do you think i should just buy it and change it??? thanks again

 

Check this thread too before buying a new ABS sensor.

thanks for the link..i replaced the stoplight switch a few weeks ago..i DO have front abs and the front pass side one is open..so it need replacing..the other ones are good...can i buy this part ..the parts store couldnt tell me if it comes as one unit with the hub or not.. also how do you check if the hub unit needs replacing?? cause that one tire on that side is bad...

 

the light was going on and off for awhile there..got it fixed it was the fron pass side abs senser..thanks for all the help

 

Thanks for posting back with the findings and the fix.
That will help someone in the future who is experiencing the same symptoms and tries a forum SEARCH.

 

just a little more info..the ford hub piece with the abs sensore was cheaper than with out so my friend bought it with...well the asb senser is the same as the dodge one so i just spliced it on to my old wire..works great and didnt cost me a thing..ya ya i know its a ford part but it works

 

I am also having problems with my ABS and brake light coming on. I did a burn out in my 2wd 2500 and I noticed the sensor on the diff could it be bad or is there something on the front that I need to think about replacing?
