Thank you both, I think you are right about the bearings starting to seize up. I didn't read your post until now and about an hour ago I decided to man handle it and pull it to the right and it worked so I pulled it to the left hard and it worked. I started driving the unit around the shop move the handle every direction and it really turn fine now. I think the bearing had rust in them and I may have broke it up. Thanks for your import. Now I have to figure out why it does lift up or down.
