99 Civic EX - After doing a brake job, with the front end lifted up, when I run the engine, the driver side hub is turning forwards slowly. (*) The force on it is so light I can easily stop it with my hand and the wheel doesn't turn when the tires and rim are mounted. When I press in the clutch the hub stops turning, so it looks like there is a bit of engagement. I'd really appreciate your thoughts on:

1) What could be causing this?

2) How to fix it?

3) How much am I harming the car by leaving it in this condition?

Thanks in advance, guys!

(*) I haven't noticed this when the entire car was up on stands (and level) but I wasn't looking for it so I may have missed it, just throwing it out there in case it may be relevant.

 

This is normal. Nothing to fix.

 

normal.

 

Thanks for setting my mind at ease guys. If you don't mind letting me know what does that.. Curious minds'd like to know

 

The fluid in the trans is what's turning it. Completely normal.

 

Thanks. On a good note, it's nice and fresh :D
