Has the car had an alignment since all the new parts were installed?
Check the LCA pivot mounts and torsion bar sockets, check the adjusters to make sure they’re not stripped now (no adjustments with weight on the suspension). Check that the end links on the sway bar are set the same.
And yeah, check the rear suspension too. If you have SS springs back there the front will not have the same adjustment left to right with the front end level. Or you could have a broken spring, etc in the back.
