I think at this point "IF" you've had all the wheels and tires checked for balance and out of round and bent rims then I would really look closely at the rear axle bearings. Case in point; a friend of mine had me drive his Suzuki Grand Vitara on Mon. He just had new tires, balance & alignment done. Since the work he noticed a shimmy or shake in the front that could be felt as well as seen in the steering wheel. He had it realgned and the tires checked, rotated on the rim and rebalanced with no satisfaction. I drove it in both 2wd and 4wd but the symptoms were stiill there. The shake started around 52mph. He let me shake down the front end (check it out). I found slight play in one wheel or hub bearing. Replaced both bearings and the problem was fixed. The car has 102k mi. on it. My friend is meticulous about his maintenance. How many miles on your Ram?

So after looking over the tires while rotating, you can abviously see that there are 2 bad tires. both only have these spots. They were originaly on the front when I had my front shake issue and then when they aligned my truck they also rotated the tires to the back so I am starting to think that is causing the shaking and they need to be replaced...What do yall think?
