Want to know if i have front or rear abs

Off the master cylinder. The front tube controls the rear brakes. And the back one controls the front brakes. Just a note. I don't know which year they started doing this, but, the front right brake goes/ties in to the left rear brakes. left front to right rear. This set up runs off the ABS module to the brakes.

The front ABS sensors are built into the hub assemblies and the rear is mounted in the top of the rear differential. One would need to know where the fault is at before just replacing the sensors.
The rear one is relatively easy to replace aand the front ones require front hub assembly r&r.

I am in the UK, so do not know this model, but I am a Bosch service tech and can tell you, if you have air in the ABS unit itself, you well need to connect to diagnostic tool with bleeding/venting program on it. The ABS pump needs to run and operate the solenoids to get the air out...

Here's how to abs bleeding?

ABS was optional on S and LE models. Don't know if it is 4 wheel or not. You could count the lines coming out of the ABS pump if the car has one.

Does this van have 4wheel abs or just rear, if there was a problem with the abs then the abs light would be on, if the light is on then have the abs computer scanned for codes, the codes will tell you where the problem is,

This may be caused by a bad wheel speed sensor or the speed sensor in the rear difff, the best way to know is to have the computer scanned for abs codes, these codes will tell you where the problem is, for example it may say code p**** left front speed sensor, go to an auto zone parts store they will scan it for free.hope this helps.

you would have what looks like 2 brake hoses going to the front wheels if only 1 hose then you only have rear wheel abs which is most common

is it the front or rear locking up? you really have to have this truck loaded (load valve under bed) before the back brakes come on and i think these are the same as my 1999 2500 where the rear is only abs, and not on the front..dumb design i know, but thats how it is...determining if its rear abs only and which axle is locking up will help pin point the problem...i put 100000 miles on my dodge since i got it in 2001 and i put 8 sets of pads on the front and just changed the rear lining and thats only because the rear wheel cylinder was leaking causing the rear brakes to lock up..

if you have rear abs then yes. you may have pinched the cabl attached to the wheel bearing
