Replace tension pulley for serpentine belt on 1998 Galant with 4G63 engine with AC.

Hi.
The tension pulley is making a squealing sound, so I need to replace it.
I have loosened the tension pulley but I can not get it out because of the attached bolt in the pulley. I took out the tightening screw completely.

How can I get out the old pulley and replace it?

After removing the nut, the pulley should come off. If it is stuck, a little tapping on it should turn it loose.

Hi and thanks for the reply.

If you look at the link, you see there is a bolt attached to the pulley. This is for a 2,4 engine, but it looks similar.

After the nut is taken off and the belt is loose, I still can not get this pulley out of the track where it is. This is due to the bolt being longer than the space i can use to pull it out towards the fender. The pulley is loose and easy to move around, just not possible to get it out.

I have googled this a lot and it seems there might be another nut in the backside of the pulley(between the fender and the back of the pulley). It is extremely tight so I am unsure if it is even possible to get to this nut.

Can this be the way to remove the pulley?

I have been able to spray some wd40 into the "bearings" of the pulley when it was loose and that silenced the noise for now. This is however just a quick-fix I am afraid of.
