In an attempt to figure out what is causing a pulsation when breaking, I notice white grease on the back of the wheel bearing after I removed it. Some of the grease is on the abs sensor and inside the housing where the bearing is seated as well, is this normal and could it cause pulsating when braking? I always thought these bearings are sealed.
This is my second post with this pulsating issue...already went through new rotors, tires, pads, shims, and a caliper...no change.
