I have a 1998 SSE and just recently it developed a "hum" in the front end. The best way I can describe it is like a 4x4 with oversize mud/snow tires going down the road. It sounds like it'* coming from the passenger front. Could this be my wheel bearing or is there something else I should check?

I would think it'* a wheel bearing.

Maybe I should have also mentioned that my serpintine belt has a split in it. That wouldn't cause that sort of a hum would it?

Hang on...I gotta check with the Admins to see if it'* still wrong to slap members.

Fix the known problems, then address any sounds/issues that remain.

If a bearing is going it will hum. When you turn a sharp corner listen to the sound. Does it become more pronounced? It will do this when the bad bearing is on the outside of the corner. As for the belt, change that first and then move on. Always fix known problems first.
