Hey - last couple of times when landing, I felt a "clunk" when the nose wheel touched down and had some shimmy afterwards.
I've been trying to figure out what is going on and am starting to run out of ideas of what to check.
The first thing I did was to remove the nose wheel, clean and repack the bearings, balance the wheel, and check the breakout force (~somewhere between 22 and 25 lbs on a fish scale), and check the air pressure (35psi)
Went flying again, and still had the clunk and shimmy.
Reading through past posts, I found a few folks have had trouble with the bolt that holds the nose gear in the motor mount.
This afternoon, I had my dad come the hanger with me and had him push on the tail to lift the nose wheel off the ground. With the nose up, I pretty vigorously shook the nose leg both front to back and side to side and really did not feel any movement. The slight movement I felt seemed to be the leg itself bending slightly... I did not feel like there was any movement at the upper end in the motor mount.
I took a picture and based on the torque seal, it does not look like the nut has moved at all.
I am looking for any suggestions as what to check next. There is the possibility that I put the nose gear down at a higher than normal speed the last couple of flights... wondering if that could be my issue.
Thanks for any suggestions.
