Lately a noise has been coming from my drive train. It is sort of a "wum wum wum wum wum" low-pitched sound that occurs only (and always) when moving and increases with speed.
It is not a tire problem. I have rotated and inspected the tires with no results. Also, there is nothing being transmitted to either the steering wheel or brake pedal.
I have also removed the steering knuckle to inspect the wheel bearing hub. The hub turns smoothly and there is no play in it. However, I don't know if this is an effective test for a wheel bearing problem.
I did notice that the driver side CV half-shaft inserts into a bushing mounted about halfway between the wheel hub and the transfer case. I did not inspect this bushing but wonder if it could be the culprit?
have the same problem?
