Carrier Bearings

Hey has anyone had any probs with carrier bearings? Such as when you get a new one the bearing itself is the wrong size?? I just ordered one and got it today and it was to small so I had to order one from another place.. Has anyone had this prob?? Help me out on why it could be the wrong one since the part number is the one in the computer for it.. Thanks in advance..

I'm actually in the same boat right now w/my 79 LUV truck. Went to NAPA to get one ordered, they only had one in their entire system and then all of a sudden it was gone. I went to another place, got one ordered, then it was too big, I have been waitin for 2 weeks for my new one, finally arrives to the store, but w/out the rubber. What a joke, lol
