That's good if you didn't buy the truck pre-owned and the previous owner had replaced hubs once before. Hope that came out right. I had the same question. Is there a way to know if you have 2 wheel or 4 wheel ABS? I am the third owner of my truck and second owner had replaced huds once, left a few parts out. He went with the ones with ABS connectors because they were cheaper and in stock, the cut the connectors off. He said he "thought" that was the same way it was when he got it. I went with the hubs without the connectors because I did not notice the way he did the old ones until I got them off.
Is 2 wheel ABS on the front or back?
