So I was reading about Viscous Coupling Differentials because I always wondered which end of the car was the engine directly connected. I would hope that its the rear but I have not read that in print anywhere.

So in the US Evo's case, the path would go from the transmission to the transfer case where it splits front and read. The rear goes directly to a limited slip differential and the front goes through the Viscous Coupling Differential then to an open differential in the front. Is that right?

Thanks for any info,

i think the front differential is in the the transmission..thus transaxle? so it's just a transfer case that connects to the transaxle which splits the power to the rear diff. i don't know what i'm talking about

I found some interesting info:

Viscous-Coupling differential

Look and number 2 and 3. It mentions the Lancer in number 3 along with Subaru and Ford Cosworth.

So which one will the EVO get? I would hope for number 3 but I have not heard anyone mention whether or not it can lock.

Its not directly connected to anything. Its a differential, not a transfer case! In other word, its not like your dads SUV(in most cases).

Think of how a differential works in a rear wheel drive car. There are 3 diffs in an AWD car.

Hope that helps.

That's what I origianlly thought, but all the diagrams I have seen only have two shafts. I would love to see a diagram of a true vicous coupled differential. Anybody have one? The ones I see appear to have the same concept as a torque converter but with more coupling obviously. Check out the links above.

I was thinking that its kinda like those pics, but with a ring gear attached to the outer housing. But your right, they don't show 3 shafts.... or the ring gear... hmmmm.....

That would make sense to me. I was looking for a ring gear for the housing but none of the diagrams show one. That's probably how it works though.

Thanks for your help,
