How do you tell if this van has 2 wheel or 4 wheel ABS brakes. If the van has drums in the rear, do they have ABS, will the drums tell you that it only has 2 wheel ABS. My parts guy doesen't know, will the VIN # tell? I would like to get the rotors before I start the work.

You either have rear wheel or 4 wheel ABS.

This means if you have speed sensors in the front then you have 4 wheel ABS.

If you only have it in the rear differential then you have rear wheel only. There are not wheel speed sensors in the rear drums. Only in the differential housing.

Here are a couple guides that will help with this:

Below is all the info from the manual on both systems. Please run through this and let me know if you have other questions. Thanks
