Dakota 1998 5.2 2 wd

Any of You guys who know if the abs wheel speed sensor are the same for 2 wd as for the 4 wd? Have been searching but haven’t found a sensor for a 2 wd. The abs is activated randomly at low speed.
Many thanks in advance

It's probably rear wheel ABS if I remember on my 2000 2wd. The sensor picks up on the rear end. There is a reluctor ring on the ring gear. I have had issues with critters chewing the wiring back there because it's exposed.
