Difference between spreads A1 y A2

[rupert's]

Good afternoon friends!
I am going to buy some seals for the differential of my A2, the one from the store tells me that if I am sure if it is a differential of A1 or A2 ... Do you know if there is any difference between the differential of A1 and A2? maybe they have a different reference?
Un saludo y gracias

I have never seen different kits for the differentials. I have used the same kits on both the early and late diffs.

Ok Rickf, thanks for your answer!

There are early seals out there that fit without the ware sleeves, I always buy seals in sets with the sleeves.

Yes, but the sets with the sleeves are still the same for all the years. Overseas I believe they can still get the original seals without the sleeves but there should only be one set for all years and types.

Extensive information ....

I have an A2, so I will trust that they have never put an A1 differential on it.
Another option is to put the kit on with the sleeves.

I wouldn't buy either of those. You'll want the kit with the sleeve and oversized seals. I had a leaking differential and it turned out to be porosity in the yoke in the area of the seal. Seal kit with sleeve fixed the problem. Also, if you have a wear grove in the yoke, the sleeve fixes this.

This appears to be a factory repair kit and is what is available and used over here in this country. The wear sleeves make sure that if there are any grooves worn on the yokes that you will not have issues with them.
The A2 kit he is showing appears to be an original factory kit for use on original yokes and the A1 kit he is selling looks like a seal kit only to be used on yokes that already have the sleeves. I would buy the complete factory kit and then you know what you have is all compatible. you just have to be careful putting the sleeves on. I use oil to lubricate the yoke and then I use a vice to slowly push the sleeve on. You can hammer it on but if it goes crooked it will be ruined.

I used a piece of PVC pipe to put the sleeve on with a board over the pipe and hammer. Did several of them this way with no issues. Maybe I was lucky as none of them bound up. I did use oil as Rick stated. Here is also a picture of the pitted yoke. And yes, I like AZ brake cleaner.

I agree with Rick. Oil it up and use a vise. Slow pressure works much better than the shock and ah method. Luck does have lots to do with. Just doesn’t take as much with a vise.

The situation is the following.
Less than 1000 miles ago I put a full kit of seals and sleeves on this differential. Now I have seen that I have wear on the differential output flanges and I want to change them. but for the seal to fit well I need some flanges with sleeves.
New flanges do not have a sleeve and in this case I can do two things. 1 Buy a new kit for and use only the sleeves but I spoil the kit.
2 Buy some new retainers that will fit the new flanges without sleeve

In your opinion ... do I buy the sleeve kit or do I buy the seals?

[Mr. Recovery]

in that situation I would get the A2 set, they look like the seals for flanges with the sleeves on them.

Well, You didn't tell us that part. If you have to buy new yokes then yes if you can get the seals for use without sleeves by all means buy them. Under normal driving it will be a long time before you wear a groove in those yokes. Just make sure that the seals you are getting are designed to be used without sleeves since they are different seals.

[rupert's]

Understood, I'm going to buy them and when I install them I'll tell you the result.
