Just a follow up-
I went to the dealer and confirmed what "Pops" said, (thanks Pops!) the tilt motor is replaceable and $501 and some change. I then decided to remove the lower panel and take a look at hard it was going to be to remove the tilt motor assembly prior to ordering a new one. The lower plastic trim panel came off easily. That gave access to the tilt assembly. I found on the side of the tilt motor a small cover held in place by 3 small screws. After removing that cover, the gear for the tilt was exposed!. It looks to be a worm gear type set up. You could clearly see the outside edge of the gear which was chewed a bit on three to four teeth (the spot where it would stop and grind). The best part was that I was able to remove the gear, flip it over, and rotate it 180 degrees for a perfect fit and a new, sharp set of teeth edges. Re-distributed the grease that was already in there and put it all back together. Works great, smooth, no noise, just as good as day one from the factory!
