So i have a 2007 Ram 1500 SLT 4x4 Vin: 1D7HU18247S229627 and I can't tell if I have 4 wheel ABS or not. I only see 2 hard-lines going from the master cylinder to the ABS module and weirdly enough there's only 1 tire in the front (drivers side) that has what looks like a single electrical wire going to it. The passenger tire from what I can tell has no wire going to it at all. I have what looks like rear discs as well.

 

I would think that 2WD would only get 2 wheel ABS, while 4WD would get 4 wheel ABS...

 

Nah....I have a 2wd with 4 wheel ABS lol. Go here and enter your VIN: Equipment Listing

 

So I looked up your brakes by the Vin, you have 4 wheel ABS.

 

Mine looks different than the previous guy, it says "4 Wheel Disc Rr Anti-Lock Brakes" and his says "Anti Lock 4 wheel disc". Theres also the issue iof no wire on the passenger side brake caliper.

 

Can you post a picture of the ABS module under the hood. I can tell you if you have RWAL or 4 wheel ABS.

 

I'll have to do that tommorow. All I know is that there is two hard-lines from the master cylinder going to it and to the far right of the module there's something that looks like a rubber button on the top.

 

Mine is a 2003, you have a 2007. Verbiage changes over the years; it's the same thing.

 

You could have front ABS but previous owner removed the wire on the passenger side.

 

There’s no wheel sensor on the right front. It’s in the left hub assembly only.
