You're on page with me. Since y'all have spooked me over compressing the springs, I'd have to load up & then clean-up to go somewhere to actually change just the struts.
I have looooong argued with myself over buying a pneumatic driver but could never justify it for one job. That's been about 50 jobs ago
LoL
Impact wrench is $40 at a pawn shop. You don't need a professional tool. Cheaply will work. After your done, pawn it back. Consider it 'pawn rental'.
This....quick strut'.....thinking it's anything less then 5 hours...nah. Unless you've been switching out struts everyday. It's gonna take a few hours to learn the process.
Quick and cheap only applies to valve stem caps. Otherwise it's expensive and slow.
