so i took the truck for a lil bit of fun durin some rain...it did get stuck a lil in 2wd and hada put it in 4wd...my abs light was on but when i turned it off and turned it back on the light no longer was on now i went back out to go drive it and i heard this noise commin from the front end...it sounds like its the driversside...it goes away once u hit 30 but if u hit the brakes hard you hear it...could it be the sensor or could i have blown a wheel bearing? or could it just be mud?
