Steering Coupler

The wear happens at a couple of places:
The pin wears in the shaft allowing it to be sloppy.
The holes of the two shoes wear and are sloppy on the pin- also not the pin can wear at that point as well.
Then the shoes wear in the housing. Side to side slop.
Those couplers are not 100% from the factory. Heck even the steering g gear wears and can be sloppy.
