Question on who makes the carrier bearing?

Ordered a carrier bearing from worldparts off ebay which was listed as a genuine GM part, when it arrived it was in a green plastic bag and no box other then the flat rate box it was shipped in. The part had 10004550 stamped on the bracket which is identical to the dorman part shown on the amazon link below. I contacted the seller who provided a return label and provided a full credit. I then ordered the genuine GM part from rockauto. It was delivered today and was in a box with a GM# 92189411. When opened it had the same green bag as the part from world parts and also had the same 10004550 part number as the worldparts item and also the Dorman part on amazon.

Any insight on who makes this and if the part with 10004550 is dorman or GM and most importantly whether its a decent part to use or is there a real genuine GM part or do I have it already?

What you got in the Genuine GM box should be fine. My original carrier bearing (the one that came on the car from the factory) had 10004550 stamped in it as well. See attached screenshot where my voodoo chicken is in the original bracket.

Since the driveshaft carrier bearing came from Rock Auto in a General Motors box it should be legitimate. Have used Denso and Mitsubishi alternators, Motorad gas caps, and yikes various Dorman parts all arriving in General Motors boxes. Won't comment on Dorman parts quality.

Ok thanks, I guess it is the bearing to be concerned with and not the bracket. FYI... the GM part I have shows bearing NSK 6006DU made in Japan.

This is not the first Dorman part I’ve seen they supply to GM. Seems Dorman also supplies the spherical joint toe rods from the Z-28

Does that have the same bearing NSK 6006DU made in Japan? Looks to be the same green bag

Genuine GM part...

They are sourced from the same manufacturer and then marketed under the various brand names.
