Hey everyone,
This is my first time posting in these forums, so bear with me, and I will try to resond quickly to any questions.

So here is what is going on. 2008 Honda Civic LX
When i drive, my steering wheel shakes and the back passenger side feels like it is shaking.
This usually happens when I am going over 55mph, but happens sporadically at lower speeds as well(but with less steering wheel shake).

I have had the tires rebalanced, and switched the tires to see if it was tire related, and it is not. I also tried to wiggle the tire to check if it was a bearing, and both seem to be fine, as does the suspension.

Any ideas? Im completely stumped.
