Suspension shake from passenger rear

[lil754boy]

I have a shake in my suspension on my 2005 Yukon Denali XL. I have balanced tires several time and finally replace all. The shake is still there. Where do i began? Is this a common problem. What should I check. I have not had good experience with going to suspension shops with these kinds of problems.

I deleted the other post as it was a repost. Are you sure its in the rear? Do you feel it in the steering wheel? I tend to believe its in the front if it can be felt through the steering wheel

question how much weights did the tires take?

still shaking

I'm not sure about the weights. i rotated the front tire to the rear and the shaking stays in the rear. The steering wheel does not shake. It's the right rear.
