Just got off the phone with Bill. They (Losi) do not consider the diff case a "problem". They say the aluminum diff case was not designed to FIX a problem. It was designed to make the diff work better. Again, no replacements unless i send in the busted garbage. He did seem concerned about the trucks general issues (cvd's, clutch springs). Both are problems that should not happen. Neither of them are NEW technology. The problems there simply shouldnt exist. We shouldnt have to carry a damn box full of CVD's, and axles around. So i guess i'll take the garbage off the truck today, and send it first thing tomorrow. I guess it doesnt matter, the truck is down anyway. I did have a long talk with him about the CVD's. Supposedly the parts they designed, are not the same as what they were give on the truck. They are not happy about this at all. Neither am i, or any other owners. The problem they are having is production now. It could be another 3 weeks for the CVD's to get into production. Im thankful that Bill is willing to talk with people, and shows concern about the problems, but im back at square one again. I send them diff cases, i get more junk. CVD's?? Still junk. Still a shelf queen...
