Good photo showing how the OEM plates bow and let that bearing bang around in the housing.
We only personally know one person who's wheel (and axle) separated from the Trike. Fortunately it happened in a slow turn and she was not hurt.
We know of several dozen (still a small percentage) that have had the rear end grenade due to too much play in the axle from the bearing being loose.
What is far more common is the trike having a loose feeling, and some even hear the clicking or clunking, as the bearing shifts in the housing. This can also cause wandering, which many times is just the road surface, but other times is the rear wheels being slightly out of alignment due to loose rear bearings.
Many of them go down the same path I did, checking the heim joints in the panhard rod, checking the swingarm pivot, then checking the bearings before identifying that loose feeling of not tracking tightly.
