Hi, I'm hoping someone could help. I was hearing this low rumble coming from the front of the car just before the brakes stopped the car, and thought it was a broke up brake pad. Well, the pads are OK but the inside of the drivers side rim was coated with old, black grease that looked like it was there for quite a while. It coated the parts behind the brakes, too. The axle boots seem intact and the axle had no play, but not sure of how to check that anyway. Does the front bearing have that much grease in it to cause this if the seal went bad, or is it coming from an outside axle knuckle somehow? It was a mess to clean up. Is this another big repair job to look forward to? I just had an axle seal replaced about a month ago, which fixed a drip, and the power steering hose developed a pinhole leak and had to be replaced. Any ideas would be appreciated. Thanks, Rick 4-cyl, 125,000 miles.
