FYI - During my annual with the wheels apart I decided to get the wheel hubs inspected based on known issues with these 3-part wheels. I used Tail Wind Inspection Services at TUL. Sure enough the pilots side hub has a crack! No idea how old the crack is but it's a ticking time bomb! The bad news is that this part has been long discontinued due to cracks that have resulted in accidents! Doing some research online I've found out that the original hub was make from magnesium and the newer ones were made from aluminum. I've got one of each, I've noticed a weight difference between the two with the magnesium ones being lighter. The cracked hub is most likely magnesium and the good hub a newer one made from aluminum. In all the years that I've owned the plane I've never done anything with the hubs so it must've been a past owner I've going to go through the old logs to see if there's anything.
