Never said you should not have. My points were
problem isn't always the joints
even the balance
or even the center bearing
could have left factory that way
there are some honest shops after all
who figure out what's actually wrong
I don't know what it's called, I'll say "face angle" meaning that the flange on the front of the differential should not be vertical to the road surface. Rather angled to reduce the amount the UJoint has to flex.
The older I get the more likely I am, to change out every part I touch on a repair, hoping I won't have to go back into at least that area, again...
