At the speeds listed above, I feel wobble mainly in the rear (and sounds too) but I also feel it in the steering wheel. Any I idea what I should look for? It is more of a vibration then a wobble in the steering wheel. I do think my shocks and struts are bad, they bottom out on certain bumps. The tires look like there is no sign on unusual wear, the rears have 40k on them and the fronts are new

tires out of balance.... that gets me in the winter months, some snow gets in the wheels and shakes like a bisch
