Re: Causes of broken ball joints
OEM ball joints have no lube fittings ( well, in my '88 - they may have added them later on in newer trucks)
I had an upper fall off while parking, back in 2001. ( couldn't find what that squeek was)... soon found out !!
I just replaced EVERYTHING on my front suspension & steering 2 weeks ago. Including upper control arms, etc.
Truck feels like showroom!!
The ball joint tends to fail completely when the most stress is forcing it sideways, as in a parking maneuver .
