We had a very noticeable Nose wheel Squeak on our CH750 STOL with the rounded front tire mount. We lifted the nose off the ground in order to find the problem. After removing the wheel and checking the bearings, cleaning everything and reassembling we could not find any problems, but the squeak was still there. This noise was load enough that we first noticed it during taxi with the engine running.
Would you believe it was caused by the rubber mold whiskers sticking out from the tire !
After enough hours and in warmer weather several had worn at a slant where they were wiping across the aluminum and making noise. If Daughter had not said the classic "this might sound crazy, but ..." we might still be puzzling. After removing all of the whiskers the noise quit.
Maybe we will save some one else some time looking for the mysterious squeak.
