Has anyone done this? What can we do with AYC after replacing the rear diff with a rear RS type differential so the AYC won't give errors?

I'd like to make it work like with 8s and 9s where we disabled AYC and replaced with RS diffs but kept the ACD.


Any help appreciated !

 

I have the RS sitting and it will be installed within a few weeks. I don't think you have to remove the AYC. Here's a thread where it has been done: https://www.evolutionm.net/forums/ev...f-install.html

Btw there aren't anymore right side differential bearings in the US so if you want to do this anytime soon you may want to contact a dealer to get one ordered.

 

No errors, everything is OK
you should drown your AYC lines, that`s all

 

Drown?

 

close lines

 

Ah, thanks. But why would you want to disable the AYC if you swap in a Type-RS? I thought that the whole point of using the relatively soft Type-RS (as opposed to something like an MZ) was that it would work with the AYC, giving you something close to the best of both worlds.

 

I'm doing the Evo 10 diff to Ralliart diff swap and from what I gather, all you do is plug/close the lines and you're good to go. Apparently no errors or lights on your speedometer.

 

In my case AYC was totally broken, and the cheapest way was sheptrans kit with mechanical differential.

 

Did you by any chance weigh the components for the swap? I've heard reports of 150 lbs savings, but I simply can't believe that.

The mechanical diff itself weighs 45 lbs (weighed it a few days ago) from a 2009 Ralliart. I can't see the axles being a whole lot lighter, and I cant see the Evo diff weighing 200 lbs, all though it is huge. Maybe 100 lbs.

 

I didn't think the weight savings was in the diff alone. I thought you can get rid of lines and the pump and different diff etc and bam saves weight.

That 150lb is something I made up on evox forum lol. I just heard it saved a lot and couldn't remember, so don't quote me on that. I just know its a good amount of weight savings.

 

Evo 8 diff with 12 plates mode and DSS 900HP axles was in kit.
88 lbs for all kit

I don`t know what about stock

 

So you're the bastard who started the 150lb rumor!

Shep just got my diff, when I pull mine I'll weigh it in. I'll check the axles as well, but I'm not expecting a lot from the axles themselves, if anything.

 

As much as I know the ra rear is differ from the x so your axleswill be not long enogh or and you rv axel ends will not match with the ra diff.

 

Yea, you have to use the DSS axles that are made specifically for the Shep Swap. The OEM ones will not fit .

It's a very simple swap really, I thought it was much more complex and involved more parts, but you just get some mounts and axles and you're pretty much set.

 

You dumbarse.
