rack install failed

I can see your problem in #5 and second group #7, the rack needs to be raised or LCA inner pivot point lowered. When you say "tie rod sitting level like control arm" it needs the pivot points to be parallel, the tie rod is level but the LCA angles down.

The difference in inner lengths as you said does matter and ideally they should be the same but being parallel is paramount.

Oh I forgot, lowering the tie rod ends will help and kits can be bought to do this.
