Control arm camber bolt washer play Help Plz.

Fixed her up installed new split lock washers.
No longer getting movement on the camber bolts.

But still getting a really strange "jerk" when driving now thinking it's my steering box going bad?

I just did the complete new Moog front suspension build this is strange to me....
Head scratcher
Maybe wheel bearings? Would explain the humming, I jacked her up but wheels are not loose no play.

I am also wondering if it's even worth installing my new Q1a uca 's I could return and get what I actually need....
