Have the Mooney at annual and one of the items they noted was that the main landing gear push pull tube roll pins have slight fore-aft play. Recommended replacing the tubes with estimate 14 wk lead and 1.5AMU. Is this a common issue and is there an allowable tolerance in play? I tried looking at Service Manual but couldn't find any specific info. Has Mooney come out with a better tube (shop said something about welded vs roll pin connections) vs source from salvage?
