Evo 9 possible diff problem?
Hello there i wonder if someone can throw any light upon a problem that i am currently experiencing with my Evo 9 FQ360.
Basically i have noticed within the last few weeks that the car has been sticking at a standstill as tho there is a brake binding or something like that but there isn't. Now on full lock,especially in reverse gear,the whole car stops and binds up and feels like it is running over something and no matter how hard one tries you cannot get it to move anywhere unless you straighten out the steering and then it moves away with no problem.
Now i am assuming it is a differential problem of some description but what i wish to ask someone in the know is if it is a rear diff fault or an ACD/Centre Diff fault?
Many thanks

You can attempt to figure out if it is the rear differential or the center differential by jacking up the rear of the car and attempting to turn one of the rear wheels with your hands. With some force it should turn ( I don't know what type of rear differential the FQ so I'm not sure how much force it will require). If you're able to spin the rear tires without an excessive amount of force then this would lead me to believe the problem is in the center or front differential. Maybe someone else can chime in with the rear differential type an the amount of force that would be required to spin one rear tire.

Spider gears busted?
Sounds like you broke your spider gears in your front differential..
This is what I am getting from the OP. You can drive straight fine, but when you turn or "lock" the wheel left or right, while moving forward or backwards, it is binding or popping?
If so, I believe you've shattered the gears and would have to replace the front diff, located in the T-case.
And Raped.. the USDM Evo's have a mechanical type rear diff, while the EDM & JDM versions have AYC.

Sorry I forgot to add that with the car on a ramp you can turn the front wheels very easy and with turning the front wheels the rear wheels do not turn in unison. But the rear wheels take some force to turn them and with turning the rear wheels the front wheels move in unison
