Rattle in suspension/steering, need help.
 

Hi, new member here, great forum. Maybe somebody can help me out.
For the past 1.5 weeks I started hearing a quiet rattle when driving over speed bumps, and any small bumps/imperfections in the road. I have a 2009 Accent - 18,500Km.

First I figured it could be the recent try, dusty conditions, so I got most of the bushing, stabilization bar, tie rod, etc, suspension links sprayed with lub.
Did not help, the rattle is still there and I can hear and feel it in the steering wheel. I'm not sure where else it could be coming from. I'm no mechanic, but I did a quick visual inspection and there doesn't appear to be any obvious signs of damage, loose nuts, etc.
Could this be caused by wheel misalignment?

Any help or recommendations would be appreciated. Thanks!
