I am replacing the rear shcok on a 94 E320 sedan. If I read the instructions contained in the CD correctly, I must remove the top fastener (in the trunk) while the car's weight is on the suspension. Then the car can be raised to get access to the bottom bolt. It appears that this operation must also be performed with the spring loaded, ie.e the car raised by lifting the wheel or the under the control arm, not by raising the body and allowing the wheel to droop. Is this correct?
