I am trying to change the rear strut on a 2003 Lancer OZ Rally. I have removed the nuts from both the lower control arm and the strut but I cannot get the bolts to come out. They turn with a wrench but won't come out. I have soaked them with penetrating oil for two days and beat them with a 3lb sledge but they still won't come out.
Any suggestions would be appreciated. I don't want to have to take it to the shop $$$$

 

I'm having the same issue. I will be trying a torch tomorrow.

The one bolt closer to the center of the car came out okay, a little tough. The two nuts took a whole can of Liquid Wrench. But the outer bolt will not move out at all. It does spin though.

 

get a 6lb hammer!

Ah the joys. Theres a handy tool called a pittman arm puller, dont know if it will fit where youre working, but they clamp around then wind down to press out stuck bolts.
One time i had a stuck wheel hub, did literally use a sledge hammer to get it off. Raped the threads and ended up having to weld it back on!

 

I used this new stuff it's not oil more like liquid nitrogen when replacing lower control arms on my Galant it worked for me on some real rusty bolts froze em off hope it helps it's rusted inside of where bolt goes thru hole
