So are the 12 bolt housings identical, that is, will a 2, 3 or 4 series Carrier fit in any housing? I've heard these terms for years, but never really understood what they meant. until today!  :)

Thank you Byron. I appreciate all those who made this report possible.  As many of you know there was not much information on the COPO rear end till now. Good work!

Congratulations on a great report. Lots of good information for anyone trying to understand or work on a 67-69 Camaro rear drive axle. I do have a concern with the naming of the main components. It is my understanding that the housing you see when you look under the rear of car, that contains all the gears and bearings is called the "carrier'. The parts catalogue calls that housing "carrier and axle tube assembly. The housing inside that holds the differential gears is called the "differential case'. The differential case is available with limited slip [positraction] or conventional [open] components.

I thought the wording was right, but will check things over. Thanks for the feedback!

Nice work, Bryon.

Is "pinion yoke" used more commonly than "pinion flange"?
Title: Re: New - Bryon's axle carrier article
Post by: bcmiller on March 14, 2020, 12:40:57 PM
Yep. Say Propeller Shaft Pinion Flange and Deflector to some people and they might not understand. Pinion yoke is less technical, but more widely understood.

That is not the industry accepted use of the terms.
The differential carrier is that which carries the differential gears. Case is often used as an equivalent term.  https://en.wikipedia.org/wiki/Differential_(mechanical_device)

Some of the terminology confusion comes from the different designs used over the years!

For the Camaro 1st gen differentials, where the differential gears are 'assembled' into the entire case, the 'case' if the carriers.

For older chevys which had a 'chunk or pumkin' that removable chunk 'case' was the carrier.   Same with Ford 9' rears...

The automotive industry terms for the two major drive axle components used in the 67-69 Camaro are:  "differential carrier" and "differential case". When ordering parts or diagnosing problems on the Camaro rear drive axle the "carrier and axle tube assembly" is usually stated as the "carrier". The component "differential case" is often abbreviated to "diff case". The incorrect use of these terms has caused much confusion when discussing many vehicles including 67-69 Camaro.

Can you please clarify if “l” or “H” was used for 1968 carrier date stamping? I heard that “I” was skipped in the alphabet.

Look through this thread at yenko.net. Post 12 has a shot of a 68 unit stamped "I"

“I” was used for year. And it’s calendar year.

I had one with “I” a while back but the post Mike mentioned was confirmation of its use.

Do you have data which conflicts with that?

Based on the report and supporting photos is it clear enough to understand?  I appreciate the feedback but you need to realize it’s impossible to please everyone.

Bryon you have created a great report. I am sure all of us who read and use your report appreciate the amount of time and effort you have dedicated to its creation. The 67-69 Camaro parts catalogue and chassis shop manual NAME the part carrying the differential gears "Differential Case". I was hoping you would consider editing your report that calls this part the carrier to agree with the GM manuals. The incorrect use of the part name "carrier" has caused me much aggravation in my career. I am writing this to try and help dispel some of the confusion.

I understand your concern and I realize what wording the parts books use. The case is just that, a case for all of the other parts which are then usually referred to as the carrier.

Consider how things are worded on these sites.

I realize that many people like you and I have written adds that call the differential case the carrier. That is what has led to the confusion. I believe your report is a technical report and would be best with the technically correct NAMES of the parts. On removeable carrier drive axles [pot, pumpkin, etc.] such as the Chrysler 8 3/4 inch when someone calls looking for a carrier they are usually looking for one of three common carriers. I am referring to 1960's muscle cars. On 67-69 Camaro when a call is received looking for a carrier it might be for a carrier [converting from 10 bolt to 12 bolt] or a diff case needed for changing the ratio. Many questions will need to be asked to clarify what part is needed. That is the confusion.  Maybe I am just going stir crazy due to self isolating for two weeks.
