The pinon on a d44 came lose, I can move it around about 1/4 of a inch. Thinking its just a bad pinon bearing or crush sleeve?? Never seen this before. And the gears and detriot was just put in like 6months ago by a shop. I pulled the cover and the gears look fine. My question is, can i pull the carrier and remove the pinon, put a new bearing or crush sleeve on and install in all back it the same way it came out without messing with the backlash? Thanks
