whats wrong with drilling it?
What's the best way to collapse a bumper shock?
Besides drilling a hole to let the pressure/fluids out, is there any other way to collapse a bumper shock on a 77 280z?

I'd drive the car up against a tree. Carefully.
search the archives and you will find...
that removing the phillips #1 or #2 screw at the front of the shock and pressing in on it --maybe rapping on it with a mallett to help it along--- will collapse it fully.
Then reinsert and retighten the screw.
You can also drive up close against a wall, turn the car off, set your parking brake and put it in gear, remove the screw and then put your jack against the wall, and screw it up to collapse the strut fully.
Either way, once the bumper is off, access to the screw is easy.
No drilling is required. No fluids come out, either.
But if you drill a hole in the bottom, gas a fluids come out.
The choice is yours.

Re: search the archives and you will find...
Thanks guys, I did search the archives and found a lot of postings refering to the drilling but did not find what you posted Tony D.
I just thought that drilling is kinda messy and permanent and maybe I can find a better way so that I can reuse it. Just in case.

yes be careful if you drill.. stuff squirts out all over..
my screws were shot.. so i got mad and broke out the hack saw and started cutting.. and i hear psssssssssssssst.. i said,"wonderful, all the air is out" then i hit it with a hammer and,,, darn i got nailed in the head and ear with fluid that smelled like sweaty socks.
so be carefull if you go the destroy them route.

Nope!
once you let the gas out, there is no provision to recharge them, this procedure, no matter what, is irreversible.
You would have to find another set of shocks---which should not be hard.

Just a thought...
If your "screws were shot" then why didn't you drill them out?
Not only would you have been able to reinsert a sheetmetal screw into the hole, you will not get squirted with anything...

For the record, one of my rear bumper shocks, the passenger side, wouldn't collapse significantly until I drilled a hole in the oil bladder and allowed it to sit overnight. The next day, I could compress it without much effort.
However, all four shocks refused to collapse unless I first drilled through the screw hole after releasing the pressurized gas(N2?), in order to release the pressurized oil.
This was on my 76 280z, maybe others are different, but collapsing the shocks w/out releasing the oil was like trying to compress a strong coil spring.
Messy job but looks much smoother with the pushed in bumpers.

any pics of a 280z with collapsed shocks?
tried the removing screws and hammer method. no go, shocks are frozen in place. any other bright idea's?

have you ever been real impatient.. and just mad that day.. not in the mood to find the drill and bit.. and the hack saw is laying right there..
well thats what happened..

yea studio i have a lot of days like that although the problem isntmy car its my life and instead of having a hack saw handy i think a 357 mag would do a much better job
Forced, yours will likely have to be drilled out, either through the screw hole(need a long bit) or through the side of the shock. Get ready for the ensuing spray of stinky mineral oil!
