siezed bolts on the car, any ideas?

Apart from scrap the poxy thing, Im in need of some ideas.

Im having to change a front suspension strut on my car, the 2 lower bolts that hold the strut in place are totally siezed in, copious amounts of wd40 havent shifted them, and heat from a gas blow torch is making no difference.

Any other magic sprays I can try before i have to resort to cutting the head off the bolt, which wont help as Id need a new hub too, or the agro of getting the siezed bolts out the hub, and I really dont want to take any more of the car apart if possible.

Cheers, Lee

Are they studs and nuts or bolts ?

Cut the nut off and leave the thread ?

Try a good fitting socket and a long bar, get someone to keep hammering the socket as you try and turn it, this method has worked for me loads of times on old cars.

m8 bolt, its siezed in solid, drivers side came out fine, both on the passenger side wont budge.

Tried heat, and hitting, then tried heat and turning with a ring spanner, still no go, put a new nut on the threaded end when I hit it.

Wondering if it needs hotter temps like welding a nut on the bolt head, does that work? would that plumbers freeze spray work?

Longer bar mate, it will either go or snap, either way it's out
