I will post this information in case it might be helpful to anyone else. The part number of the bearing they sent as a replacement was 3130-01-203-9870 and that is indeed what I needed. After receiving the correct carrier bearing, I found the instructions at
this link were not quite workable for me. First, a 1 1/4" pipe would not fit over the drive shaft!
So what I used is I what I had - a 1 1/2" PVC pipe. Yeah, beating on PVC is not good. 1.5 inch PVC was too large to fit down inside to contact the inner bearing race. So I took a grinder and tapered the PVC until it fit and it was making contact with the inside race only. Don't beat on the outside of the bearing!
I tried to seat the bearing using the PVC pipe and a couple of wacks with a hammer but it was not going to go on.
I took the drive shaft and let it sit in a bucket of ice for an hour just up to the part where the bearing sits on the shaft. Then I used a heat gun on the inside race of the bearing and the metal end fitting that goes outside the bearing and got it hot to the point where it got nice and toasty, but the grease was not melting or anything. Don't go crazy with the heat. No torch!
Then I quickly pulled the drive shaft out of the ice bucket, and placed the hot bearing on the shaft with the metal end fitting that goes on the outside, and two good knocks with a hammer on the PVC seated it. Another victory!
So now I have perfect "like new" drive shafts ready for the 4L80 when I start on that in about a month.
