The steering went out on my L345DT. I removed the column and dismantled the entire assembly. The ball nut assy is trashed and the bearing races are shot. The manual says the ball nut is sold as an assembly and should not be disassembled. If it is available, it costs $645. So I ask, has anyone taken one of these apart that was intact? If so, how many bearings are there in the ball nut assembly? If I could figure out how many bearings are in there, and if there are any other pieces that are missing, I could replace the ball bearings and put this one back together. There is wear in the main screw thread, but not so much that it would not work with new balls. Once I get the steering box back together, I still have to figure out why the power assist is not assisting. Lastly, does anyone have a steering column they wish to sell? I don't expect to find a good one but if someone has a parts cow they are busting....
