2004 altima persisting vibration/ knocking

[momomof2]

Ok, so here's the deal, this has been going on for a year now. Getting very frustrated. I have a slight pass front side vibration and recently a intermitent knocking over bumps. Putting vehicle in neutral does not stop the vibration, can be felt in steering wheel & brake/accelerater.

Here's what's been replaced so far:both front axels/cv jointspass side wheel bearing assymbly2 count em 2 sets of new tires (in 2 years)several alignments/ rotations/ balances

I'm thinking tie rods, strut, or control arm, but would like to know which is the more likely culprit since I'm getting tired of wasting money at this point. I'm inches from trading in a vehicle I really love. any help would be greatly appreciated.
