I have a 2006 Dodge Ram 1500 SLT and trying to determine if it has rear-wheel or 4-wheel ABS. I ran the VIN number through the build sheet look-up on Dodge's website and the line item referring to brakes and ABS says this: "4 Wheel Disc Rr Anti-Lock Brakes". That tells me it's rear-wheel only. I also inspected the front end and see a wire going to the driver's side front wheel bearing, but nothing going to the passenger side. Would there be sensors on both front wheel hubs if it was 4-wheel ABS? Also, where is the rear ABS sensor located, is it on the rear diff or should it be at the rear wheel hubs?

Regarding the ABS behavior, I just got the truck and noticed that there doesn't seem to be any ABS activation when I try to stop on a snowy road, I'm trying to determine what it is supposed to have and what to expect. I don't feel the brake pedal pulsing and all the wheels seem to just slide, enough to get the rear end to slide out to the side (the ABS warning light is not lit). My wife has a 2007 Ford Freestar minivan with ABS and with that I definitely notice when it is activated, the brake pedal pulses and I can hear and feel the brakes working and it maintains control, I'm wondering if I should expect the same with the ABS system on my truck or if the behavior I'm seeing is normal? Thanks in advance!

 

Welcome to the forum. It is rear wheel only, just like my 08 BigHorn. The one on the front wheel is for the cruise control. Mine has never pulsated either.
