Rear Axle Carriers

[cadmanof50s]

I have not been able to find any thing in-the CRG site on the different carrier series.
Is there a link that explains the differences and how one can identify which is which.

Thanks!

Vic, there will be a casting number on the carrier. Post that number and we can tell you what you have.

Thanks Ed,

I did have this number from an old picture I took a while back. But this is the Axle Code: BP0228G2 which tarnslates (below). I will get the casting number when I crawl under the car tonight.

Thanks!!

The casting number is 3894859 NF.

Vic, the 3894859 is the casting number of the center section (some call it the "pumpkin") on the 10 bolt rear end. You can read more HERE.

Sorry Ed. This shows my ignorance.
Where do I look for the carrier casting number?

Do I have to remove the differential back cover to determine which series is in the rear axle?

[bertfam]

The 2.73 axle used a 2 series carrier, so if the car still has this gear set, no, you don't have to remove the cover.
