Tintop suspension spring replacement
hi all,
im having to replace the front springs of my corsa because one of the springs sheared in two and started rattling all over the place! now i have
removed the suspension strut from the car without any problems and i have put my spring compressors on so i dont get a face full when i remove the top
nut, but thats my problem i cant get the top spring undone! 
its am 18mm nut and im using a breaker bar on it and an extension on that but when i turn it the entire damper turns with it, i have tried using mole
grips on the damper tube but still no look, have any of you got any wise words or tricks of the trade you would like to share to help a por guy out
Cheers
Alex

We had this problem at college. We ended up having to use an impact gun and even then it took ages.
How long can i resist the temptation to drop a V8 in?

on all cars i have done springs on there is an allen key hole in the top of the damper that you hold while undoing the nut with a cranked ring spanner

Angry grinder to kill the nut, with spring clamps in place. Then refit with new nut.

This man has the answer - no need to got attacking it with a grinder or mole grips 
Look on the top of the damper rod and you'll see a hex/allen socket - usually around 8mm. Use a cranked ring spanner rather than a socket and
then use the allen key to lever against the spanner. Often best to hold the damper unit in a vice agled slightly away from your face in case the
spring gets a mind of it's own too.

Thats the best way - slacken it off to 'just staying on' whilst the wheels are on the deck and then make sure that you have the spring
compressors on properly. On my old 205 the allen key part was missing and it did take an impact wrench (although handheld electric in my case) to
free it off.

yeah you might find it easier to get it started if you've not compressed the springs (just remember and put the spring compressors back on
before you take the nut off  )
but they are a right PITA sometimes, some of the worst ones I've done had a #20 torx in the middle

thanks for all your advice there guys in the end i went with an air impact wrench that i remembered i bought ages ago but forgot i had it until today,
got the nut off in seconds! fantastic bit of kit, ive given each strut a good going over with the wire brush on the drill and then put them all back
together and they are now back on the car, here is a picture of the bit that sheared off
