Strut mount removal, help wanted
I was trying to replace a bad strut bearing and I can't get the mount to release from the strut. The nut has been removed. The only thing holding the mount to the strut must be corrosion. I'm stumped. I've tried heat, PB blaster, releasing the tension on the springs, steering wheel puller, 3 lb hammer... I also tried remounting it and pushing down, but that didn't work either. Anybody else run into this problem?
I'm thinking of taking it to someone with a hydraulic press, release the springs, and compress the strut until the springs push it off. The only other thing I can think of is burning away the bushing and then cutting away whatever's left, but there has to be a more elegant solution. Any (other/better) ideas? Stock ROW M030 suspension and mounts if that matters.

3 lb. does not count as "BF"...

Don't hit it with a hammer that can dent the threaded shaft. Is is an odd thread/size and repair would be a bear. Try a soft wood block and a few hammer hits. Heat the plate, soak in some penetrant, reheat and wood block/hammer hit it a few times to shock it loose. If that fails a press will work in short order. I can help with it this evening if you can get it and feel like droving to falls choich VA.

The first thing to try is loosen the spring compressors, for two reasons: A) It looks the spring is crooked and that could be binding the top hat; and B) the spring is usually longer than the strut, and might help push the top hat off.
Otherwise, you can give me a call. I just sent you a PM with my phone number.

Thanks for the many suggestions. I ended up drilling out the rubber bushing in the mount (which I had planned to replace anyway) so I could get the spring off. I cut down the piece that was still stuck so I could get a wrench on it. I was able to spin it but not unscrew it until I got a ball-joint fork behind it. What a pain. But it's off and the threads aren't damaged.

What did you do between the 2nd-to-last and last photos - what a transformation (looks brand new)?

Just PB Blaster and then wire wheel. It's amazing how just a little corrosion held on the mount.
