Hi All

Whenever I drive over a manhole cover or other imperfection on the road, the rear end of the car feels like it's stepping out. When I had the car serviced in December I asked them to give the suspension a once over and they ended up replacing the front drop links. I drove fine for a while but I can feel it starting to do the wiggle again.

Any ideas as to what might cause this? I don't just want to take the car in and ask them to find the problem because a lot of places will just start replacing everything till they find the issue (or not).

Thanks,
R
