Any DIY methods?

ALSO.. LOTS of pot holes and speed bumps right outside my house. I have hit them multiple times at night without thinking. EVERY TIME I do, I only think to myself "I want to smack the guys working on this road."

I had a shaking at high speeds that only seemed to show up when decelerating. Ended up being a blown differential bushing with goo leaking everywhere. I balance my rear tires and the shaking lessened, finally went away when I replaced the bushings.
