Need some opinions here. I just purchased an 05 Outback and it drives fine on regular roads. On the highway, however, I noticed it bounces and sways a bit over road imperfections such as bridges or undulations in the road surface. The suspension feels good otherwise...rides nicely and no clunks or noises. I've never owned an Outback before so I'm wondering if this bobbing, bouncing suspension is normal for this vehicle? Any help would be appreciated. Thank you.
