djradz - I thought of that "no seal" problem too. If someone was going to be using the guide wheels a lot, such as someone who puts in lawns or something, then that would be a problem. But, for me it's just once in a while for the last few passes while leveling and area I'm re-doing or patching, and while pushing snow in the winter (it doesn't snow much here). So, I think I would be OK as long as there was a zerk to push grease in there, which would push the dirt out. Your'e right about the cost approaching the cost of a kit, so I need to find some better prices. A local store called Big Blue (local to southern Indiana) is going out of business, so I'm going to see if I can get something at a clearance price. I don't know if they'll have what I need though. I plan to go down there on Thursday (that's "kids eat free day" at the Tumbleweed resaurant).
