The root cause of my problem was a worn out front deck, which resulted in the front axle not staying in place. While this sounds like a huge repair job, it's not. Only 4 bolts hold the deck on, the new placement deck fit like a glove, now my mower works fine. I also replaced the front axle, just to be sure, so my "front end" job cost me a lot less than a new mower!
