[Beginner] Replacing rear shocks: marking?
I'm referring to the workshop manual: Ford Workshop Service & Repair Manuals - fordrepair.info - 2011 Mustang Rear Suspension Shock absorber
So in steps 2 and 6, it mentions marking the shocks when vehicle is on level ground--so one can raise it to that level during replacement.
1. Why? What's the purpose of this?
2. How? The shock is stuck way in there; how can I get a proper reading on the old shock and transfer it to the new one?
