Started my gear swap last night. Stopped when I realized the pinion bearing they sent me were wrong. The inside diameter was right but outside was too small... Went to oreillys this morning to get new bearings and races but they said the ones I had were the right ones.. couldnt even find anything in the computers that were the size I need. Had a koyo part number on the old stuff but their computer wouldn't cross reference it... weird thing is everything else in the kit was right.. and its only the inner and outer pinion bearings and races that are wrong.. the truck is an 09 Silverado 2wd. 9.6 rear with g80 if that matters. Need help!
