So, the evo has been in stands waiting to get the calipers back from coating and rebuilding. I noticed when I turn the car on, in neutral, the driveshafts start moving slowly forward both front and rear. If I grab the rotor they will stop but continue once i let to...what's wrong here?

 

Most cars do, and many 2WD vehicles will even spin the wheels while in the air. Not really a concern.

 

^bingo

 

Yeah this is completely normal Nothing to worry about!

 

^ agree

 

Mine do also

It's just fluid in the transmisson "connecting" the gears and moving them. that's why you can grab it and stop it with minimal effort

 

Well, you guys are awesome. Thanks. Thought for a second something was ****ed up. get kinda paranoid when my car has been sitting for so long.

 

I mean there's a possibility that the clutch could be dragging too. I'm surprised nobody brought that up

 

The clutch ain't just dragging fellar, the turkey is fully engaged! -The transmission is in neutral, and presumably the OP's foot is not depressing the clutch whilst outside the car scratching his head at his turning wheels.

 

^ this. you'd have to be in gear with the clutch in to tell if it's dragging or not
