Replacement of Shocks brakes and calipers On. A? 1971 VW you double cab.

It took me over three hours to do the right Side break caliper And shock and regrease The hub bearings but I would not have got the shock or the caliper off without WD.40 As these items had not been off in a very long time and I cracked my wrist and a couple of ribs hyperextended my left elbow and had no strength in my hands. To get these items off so your product WD.40 Was the only saving grace to get these items off this venicole? Thank you so much for your product!
