Re: "BE" axle info
Rob, Thanks for the assistance. As I have stated before, I'm not really sure that the carrier in the pics was the one that came with car.
In any event, that carrier was replaced with a new Eaton S4. The old one was swapped for some other parts that I needed. Andy

Re: "BE" axle info
Not to hijack this post but... I have just taken apart my " KQ" rear and have some numbers to post as well..Ring gear 2 GM 3862526 10 41 4 69. Different part number than the BE rear posted here but what is it? Rear number is KQ 0624 for a third week of July COPO Chevelle
On the flange of the carrier E 27 J is stamped. I wont have the posi unit out until tomorrow although I fear the worst as the springs are green in color and appear to be small diameter wire not to mention that I can turn the rear wheels in opposite directions and watch the discs slip. Thanks ALbert

Re: "BE" axle info
Albert
The E27J on your carrier is the correct code and the date spread is within range, about a month apart. Your carrier casting date is probably 70 to 100 range, I'm guessing. On some of the later cars, the posi date to axle dates were a little further apart than during the high production months. Compare you unit to the pics that Casey will be posting and the id characteristics in my next post. I wouldn't worry about the green springs until you check the other features. It may have been rebuilt in the past. I will put the date data I my next post. The ring gear is a standard 4.10 with a 3862514 pinion. What is the casting date on the housing? Hope this helps. Eric
