I finally got around to getting my lower control arms modified last night.I used a greasable rod end to make them. I think they turned out pretty good. Now let me know what you think.

Looks like good work but wouldn't they now have the ability to twist or move fore/aft under braking/acceleration? The range of motion is supposed to be up/down arc with no fore/aft movement. The only other items stopping them from moving are the strutrods? Are you installing adj. rod end strutrods?
Is the next step to box them or is that not necessary?
Not an engineer but that's the first thing that pops into my mind when I see that rod end ball/socket is different planes of movement.

Yes I am going to be using adjustable strut rods. But how do you figure they will move fore/aft? Take a look at the TCP lower control arms. They are mounted this way. Once the strut rod is hooked up that will stop the fore/aft movement. What I am trying to do is free up the movement of the front suspension by taking all the bind out of it.The whole front suspension will be mounted in rod ends or roller bearings.
 
The strut rod is what controls fore/aft movement. T/A Boss 302's used a monoball setup like this. I am wondering what the rod end is load rated at being that it is greasable and has a hole drilled in it for the grease. I would plate the bottom of the arms too.

I would also use some Seals It washers on the rod ends to keep the dirt out of the grease on the ball.

A friend of mine did give me some boots that go over the rod ends. They kind of work like a fust boot for a ball joint. It covers the whole rod end and gets filled with grease. He only had 2 of them and the company that made them went out of business so i am going to have to use Seal It washers on the strut rods. As for the load rating the guy I bought the rod ends off said the threaded end of the rod ends are stronger than the ball end so they loose no load rating. I did use chrome moly rod ends so the should be more than enough to do the job.
