4WABS...
Okay, I know the broncos had this option, the 94+ had the different knuckle for it spindle was either machined to have it or not. Has anyone ever actually done away with RABS for a 4WABS on the trucks? looking over wiring diagrams it looks feasible say using ranger or explorer motor and electrical, 96 ranger uses same front abs sensors, I was even comparing older part numbers for abs computers between bronco to explorer(93-96) they were the same. Some insight, help, pointers anybody? or am I the first for this one I have not ever seen this asked before.
I am use to the truck, I know how to stop it, it does have it's advantages and disadvantages. I have also had truck borrowed and brought back with "I almost hit (blank) because the brakes locked up when I hit them"
So let me know anyone if you have done this, I am going to do it one way or another.
Thank you,
Curtis

ABS does not decrease stopping distances it increases them, so if your truck had been equipped with 4wABS you would have been looking at collision repair not just a close encounter story.

On snow covered, sandy, gravel, or dirt surfaces, locking the tires can help dig through the lose material to better surfaces for the tire to grip. With ABS, the tires would continue to roll over new debris which can increase stopping distances.
In almost all cases, ABS's largest advantage is to help in-experienced drivers maintain control since sliding tires can kick the vehicle sideways. It's not necessarily the best option for improving braking distances.

Yes that is what the science says though real life sometimes doesn't quite agree. I remember hearing about guys at car dealers and service centers running into the bay doors when ABS was first introduced, they were pulling up to the doors and stomping on the brakes in a hurried manner.. not going very fast you know just parking lot speeds. They weren't doing anything different than they had been doing for years before ABS but now suddenly that quick stab of the brakes caused the wheels to lock momentarally which activates ABS so instead of skidding an imperceptable distance the brakes let go and the car slams into the door. Yes current ABS systems are much better than those early versions but I find it's still pretty easy to get the ABS going on dry pavement in my comparatively modern(2004) cars and trucks.

Also GM trucks with 4wabs when front wheel bearing goes bad and touch the brakes and they start just setting off due to signal failure(dropping out). That is why I was looking at newer ABS set up little smarter not sure on the last of the 5.0 era explorers.
