Hi, I'm having somewhat of a problem when driving at highway speeds. On a very smooth highway, the car is a blast to drive, steers straight, no vibrations, etc.

But on most highways around here (Quebec roads are really not good at all!) The car likes to "Squirm". If I were to drive over a crack in the road, the back end feels like it wants to give away. It gets so bad that I have to constantly drive in the slow lane, under the speed limit.

Now the car is solid & the suspension seems good, any clues on where to look next? Any thing I can do to help my situation any ?(subframe connectors, etc)?

Thanks,

 

Well that "Squirm" you feel is the price we 3rdgeners pay for a having a solid rear axle, bump steer is a bit(h. Some easy fixes for that are a pair of LCA & panhard rod.
