Thanks for the advice. It sounds like the next step is to get the car up on stands and have a good look around at the bushings as well as any oil leakage from the shocks. I live in Minnesota and I think the cold and salt takes a toll on the rubber components.
I did take the car out a couple times on a rather bumpy road today with some deep manholes. It does pitch a bit, but I don't think it is anything more than expected with this suspension. The rear does not rebound well, but again, I think I will start with a better inspection of the bushings.
