drop the deck, remove battery and trey. take clip off of shaft holding steering gears and the nylon plastic peice union which they call the support shaft. also i took off the clip holding linkage going to wheels. the u bracket is bolted from the botton- 4 bolts, thats why you have to drop the deck. it will all come out then. the steering shaft has a torx head bolt in the end of the shaft you can reach now its loose. they used loctite at the factory so it will be tight.
its a shame that the support shaft is nylon when the gears are steel. mine is totally worn out. i am going to sleeve mine with an oilite bushing, i have small machine shop to do this in. i suggest you look at that part while it all apart. i dont want to ever do this again, its kind of a pain. good luck
