hmmm... thanks every1 for quick reply. I tink i am gonna take the whole Coilover out and soak in it WD40 alike substance and hope it becums loosen up..

Will try the ice substance as well. Good idea.

Btw tried WD40 and many other type of degreaser,lubricant etc. Refuse to let go. Even use hammer an hit th adjustment spanner as mentioned already. Took the coilover out as well. Clamp it and tried with 2 ppl to loosen it. FAILED!!

I hope it jus need a good soak in "WD-40" land for a gd 24 hrs before it lets go.

ANY1 with any experience pls post further info.
