Romigenv,
here is a tip to consider. Those shackles hanging from your brush bar equate to a dented hood when that brush bar decides to give and rotate, thus smashing a nice crease along your hood. Yes, seen this happen alot.
Do yourself a favor and don't do hard recoveries using the brush bar or you will be sorry sooner or later. At best a dented hood and a sick stomach, at worst, brush bar gets airborne and someone gets hurt. Seen that too BTW.
As for spring removal, I have done both, bottle jack in front, spring compressor in front.
I have to say the spring compressor scares the hell out of me with that massive stored energy... I think I used a shitty little ol rented SC, however, using a better one, if I do it again, should calm my fears of a SC letting go.
As for the rears, regular floor jake and my highlift does the trick since I have sliders.
