After replacing both front wheels, which were badly worn out, I replaced the adjustment piece thinking this would solve my problem. That was very simple, just 2 bolts.
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!

It was very easy to figure out online what parts I needed. Actually bought extra Flange Lock Nuts as I didn't realize that they came with the axle assembly but it was no big deal. Borrowed a socket wrench from my son and the rest was a piece a cake. For around $35 including tax and shipping my lawn mower is like new. Used it yesterday!!
