Center Diff is out??? Front wheels spin like crazy in launch! HELP!
Hello, I have an 2003 Evo 8 and about 51,000 miles. Whenever I launch, it pulls really hard, but my friends say and I also have it on camera, that my front wheels spin like crazy and the rear don't. But in the rain or snow, all 4 spin. So my question is, is my center diff out? Or is the stock viscous center diff favor the front wheels more than the rear, because it seems like the differential distributes the power a lot more to front as they spin, and rear don't.
Please any input on this would be appreciated!

It happens to my car sometimes depending on the conditions. I think its due to how the weight is transferred to the rear of the car, giving the rear tires grip, while removing grip from the front.
So the fronts will break free.

its called weight transfer. When u launch most of the weight tranfers to the rear wheels making it grip more than the front. dont tell me u never did a donut or drift a little in ur evo? ur notice there plenty of power to the rear wheels

today i went out and showed my buddy hugh who is very knowledgeable about evos and showed him how crazy my front wheels spin and he said my center diff is basically very worn out!
so, i looked at sheptrans.com and they offer a t-case rebuild and it says how they
Replace spider gears with heavy duty treated gears
New seals
Reshimming
Neodymium magnet
We also upgrade the cross shaft retaining pin to a 5mm pin We also reshim the frt diff and replace all seals
would that basically fix my problem and my center diff would grab like it's supposed to??? or do i actually need to buy a center diff?? thanks..

To the original poster, this is normal. The weight transfer unloads the front suspension which removes a lot of grip from the front end.

Actually only half of the center diff is in the T-case. It's hard to explain without having a cut-away diagram of the transmission.
It's not a traditional differential like the front and rear.

O, ok i understand, so basically the t-case rebuild wouldn't touch my center diff correct? Because all i read about it is how it works on the front differential, so is there any service out there that can do a center differential rebuild or fix, just wondering for future???
and how much are oem evo 8 center differentials, 2003 viscous one's....??

I've never heard of anyone getting a rebuild on a center diff. It's not one component but actually a few seperate pieces in the t-case and trans. As I've stated before, I doubt you have anything wrong with your car. I've made over 75 passes at the track and nearly everytime the front wheels spin due to weight transfer.
