Calculating 3-Link or 4-Link Control Arm Forces
I am designing a 3-link for my car and am looking for a reference to calculate the forces in the control arms. I've made an assumption of the acceleration and that has given me the forward force and torque of the axle. Now I want to get the control arm forces so I can properly design the mounts. I'm ending up with one equation and two unknowns and need to find out what I'm missing.

Read the Ron Sutton rear suspension thread above, he discussed rear link forces.

I have read that post and it is definitely a good one. I didn't see anywhere in it where it shows how to get actual force values in the links. I am designing this chassis in CAD and am running it through FEA software to get stress results. To run the FEA more accurately I need a reasonable way of estimating the link forces.
