I am about to start making some upper control arms for a 05 F150 4x4. The upper arm is going to be using a 1” uniball bolted vertically (bolt vertical) to the upright. The arms will not be interchangeable. So which side should the circlip be on the Uniball? Top or bottom? Its hard to imagine where the force will be going and if this matters. I looked at Camburgs and True Travel Dynamics and it looks like the circlip is on the bottom, or upright side but its hard to tell. Thank you.
