To work on underside at front I jack up under the front bedstead/frame.
I want to check king pin wear; where do I place support so bottom springs are not compressed, ie as in driving mode??
Advise gratefully received
Not sure I understand. When You jack your Morgan up the wheels are off the ground and main spring as uncompressed as they can be unless being held up by the shock from going to the bottom. Certainly not the "driving Mode". About all you can do is to check the wear in the bushes. Maybe somebody else can explain this better than I.
