hello friends ...

I have a problem with my Jeep Grand Ch 93 model ...

my problem is with the ABS ...

the problem started when I took my car to a garage ...

there was some noise in the rear differential ... the mechanics told me that the bearing is the problem and it needs to be changed by a new one ... I brought them a new one and they changed the bearing ... after that they also told me that the front axle rubber is broken and that I had to change it .. so I brought a new one and they changed it for me ...

my problem is that the ABS light started to light when I started to move ...

the problems is from about 1 month ..

when I start the engine .. the light is on .. later it goes off ... till I move at speed more that 10m/h the ABS light goes on ..

so can any body tell me about this problem and how to fix it ...

to remind ....

where r u dears ? please , help me

John, My ABS light stays on all the time. I am still searching for an answer.

Only 3 things will make your ABS light come on and stay on. The hydraulic unit, electronic brake control module, or the wheel speed sensors. Sounds like they screwed with the speed sensors. Rule out hydraulic unit if no hard pedel.

Thank you ... but how to do so ?

How to rule out the hydraulic unit ?

where is it located aand how to do it?

if the light only comes on when the vehicle move, you probably have bad wheel speed sensor(s) or the metal ring the sensor picking up the signal broke or have miss teeth.

Where are those speed sensors exactly located an how easy is to replace them ?

Thanks a lot.

on the diff housing!

i think there in the drums.

Actually since you had the CV boots replaced I would guess they would be the front sensors. The tone rings are located on the front axles. If you crawl under your jeep and look at your wheel from the back side you should be able to see a many toothed ring near where the CV boot attaches (towards the wheel). The problem is that you probably can't tell anything is wrong just by looking at it(unless there are teeth missing). You'll need to get the code that is generated by the ABS unit to diagnose the cause of the light coming on. I'm not sure but you can try Autozone. They will usually read engine codes for free but I don't know if they can get ABS codes or not.
