i have the zc diff out to swap the ring gears and the bearing on the backdide of the diff(pass side) sounds a little weird. i can hear it when i spin it. with further inspection i just found a dark spot in the metal on the outside. as for the bearing is it the same as the usmd si dx or hf diff. whats the specific name of the bearing when i ask to order a new one.

 

 

i have it and its not in there

i found what i am looking for asses
