Sick of the front end being slightly lower on one side, so had a brain wave and decided to dismantle front suspension and rebuild with the parts I got ready for better weather (as if in the uk!). Things going great until the strut collar nuts were seized on both sides

Left side I eventually got off by gingerly sawing through the 'ring' so I could split it in half.

Right side came off with 24" stilsons (pipe wrench for USA?) and a length of scaffold pipe.

Struggled for hours getting them both off but I suppose there is some satisfaction I finally cracked it (and a few knuckles)

Some one suggested I should wrap the threads in PTFE after assembly to stop water getting in and causing the same problem again, what do you all think?
