Not sure what's going on. I put the belt on it just comes back off. Also i hear metal on metal squeal and it looks like my crankshaft pulley is a bit wobbly.

Any ideas?

It's a 98 legacy outback with 2.5.

Have you done a timing belt recently?

It's been a couple years but the car doesnt get driven alot. Seems weird that it would come loose now but could be.

Maybe it just needs tightened then? I've had a few subarus and never had this happen haha.

I've had a head gasket done since then too but they probably didnt need to pull the crank pulley for that I wouldnt guess.

Crank pulley needs to come off to get the timing cover off

Maybe the rubber is shot. The outer ring is mounted on the center part with rubber. Or, the bolt was not torqued tight enough and the pully is spinning on the crankshaft. The crank has a key and the pully has a slot to keep it from turning. I have had the bolt loosen up and the key will wear out the inside of the pully. The key only goes into the pully about a quarter inch.

A friend made me a tool to hold the pully while torqueing it.

It ended up the harmonic balance needs replaced. 

Used ones are easy to come by and they don't fail often.
