Dynamic simulation forces in my joints are not adding up

I have this lift deck trailer we want to use for a shop trailer, and the results in my joints are not adding up. This model is half of the trailer with a 10,000-pound load on the center of the deck.

1. I have a prismatic joint for the cylinder with driving positions, so I can look at the driving force on that joint to get my cylinder size.

2. When I do this and look at the forces or moments on the joints, they are not coming out in a way that I would expect the force to move through the linkage.

3. I cannot export parts to FEA, and I have tried to set the subassemblies to flexible. When I get parts to export, the forces do not match the output grapher.

Could someone help troubleshoot what I have going on? I'm running out of ideas due to my limited knowledge of dynamic simulation.

if I make any subassemblies flexible dynamic simulation will not run and it will say it's over constrained with this exporting is not working for me.
