ABS kicks in at low speed, dry pavement, 95 Tahoe 4x4

[MotoCARR]

Just picked up a new to me 1995 Tahoe with 205k.

Example scenario: Coming to a stop at a light, 100% dry pavement, about 5mph mark.

If I brake early and apply light pressure, ABS does NOT kick in.
If I brake late and apply heavy pressure, ABS does NOT kick in.
If I brake at medium/normal pressure, ABS does kick in a few clicks.

I was told that the front wheel bearings had been replaced. Looking at Chilton manual online, I didn't see anything ABS related in the removal/installation process, but they only had 2WD listed.

Is there a difference when doing them on a 4x4 and or is it possible to just replace a sensor? Unfortunately the online manual only has text descriptions and no pictures!

Sensor likely damaged during bearing work. Do both at same time.

So these can be replaced separately, and they aren't "made into" another part like the caliper where I would have to replace the entire thing? Just trying to get some research in before hitting the parts stores on the way home from work!

Sorry, yes can replace separately.

Nice rig, pull the rotors and clean the TONE ring (the ring with the steel teeth).....
