How do you know the crank journal is worn? If it is, it could last a long time. It will just be a nuisance to listen to.

I forgot to welcome you to BGW. WELCOME!

This is the right place to find parts for your cart. Check out the for-sale section, or start a post there asking for the part. These guys are awesome. I think you need a few more posts before you can access that section though. Post away.
