I use C220, just change new tire 215/45/17 & align the wheel, with lower arm rubber bush replacement. When I drive down from the steep bridge, it has a little bit sway to right side everytime. What should I 've to check? Is the shock absorber cause this problem?

 

What do you mean "sway to the right"? Meaning the car dips down to the right or car goes to the right when you have the wheel straight?

Sorry for unclear, it slip to the right side a little bit then back to normal. The wheel is straight at that time. It happen when jumping more than 100 km/h or faster.
I guess might come from rubber bush, but don't know which one I should look at .

 

Did you ever change the steering dampner between the steering linkages or control arms? It's like a $40 part and you can do it yourself in 10 min.
