Thanks Kebower for your concern,
at least I thought about the dangers and you are right I don't have much experience of working on cars.
I received the sway bar bushings and was happy when they turned out split. I mounted them on Saturday with both rear wheels on leveling boards I have from my motorhome. That part was easy and done safely.
I haven't received the sway bar links nor the shocks yet but I'll be careful and keep the rear axle level when working on the sway bar links.
Any other hints?
