If your tire is truly leaning, you either have bad wheel bearings or worn king pins. If there is no oil leaking from the hub, I'd lean towards worn king pins. Jack it up and see what's loose.
The dash should light up all 8 segments when you first cycle the key. If it does not, then you'll need to send the dash back to the repair shop. Ag Express is who I recommend. If they were the ones who worked on it last, they might stand behind their work.
