What brand/type lower control arms?
1) did you possibly not tighten everything?
2) bushing type might be the issue... Rubber vs poly vs solid.
3) if there no longer is deflection in the LCA, something else might be showing slack that originally wasn't evident because of the original LCA deflection?
Idk. I'm pulling this OOMA.
