What happens is that the heim joint allows for moving through an arc. When you install the adjustable strut rod you set the length at ride height and as 72nublu said you have to move the LCA up and down to insure there isn’t any binding. If there is, you have the rod the wrong length or something else.
The heim has to be installed so that the joint is verticals, and not parallel to the ground. IOW’s, the bolt that attaches the heim to the frame must be running left to right and not up and down. If you do that, the heim allows the strut rod to move through an arc without binding or pulling or pushing on the LCA.
And there is no way on God’s green earth that the LCA can come off the pin, even a skosh if the strut rod is installed correctly.
Like I said, even if I was going to use rubber LCA bushings I would still use adjustable strut rods.
