That's probably not enough to worry about but I may try and correct it if I can find an easy way. I did discover the real problem, though. When I put the plane up on jacks and spun the wheels, the left main and nose both spun about 1-1/4 turns. The right main would hardly turn at all. *The axle nut on the right wheel was one flat too tight*. The wheel was dragging and my brand new tire had several flat spots on it. When I loosened the axle nut, the wheel turned freely so it wasn't the brakes per se. I DO need to inspect the brakes on that side as well because things got pretty hot over there. I'm just glad it's not the oleo strut! Do we have an end-play specification for tightening the axle nuts? Thanks for all the suggestions, everybody -- --------------010008060302030302080003 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit This morning I checked the alignment of the MLG wheels and they weren't off by too much: 0.2º toe-out on the right wheel and 0.6º toe out on the left wheel.
