I am in the process of getting this looked at. Could also be due to air ride system in car for the back of the car. Air ride does not raise car in back anymore.
I've noticed the jerking when on the freeway the most and hit a pothole. Thought it was front end alignment since minneapolis has the worst pothole problem in the world - and no money to fix them all. After reading all these other reports I can see this is the more likely culprit. I'll have to sell my car to get enough money to replace them.
mine started right around 100,000 miles. but its totally understandable. the car has alot of miles on it.
