Lately the ride appears to seem rougher than usual, like I feel every single bump in the road. Tires rotated and pressure OK.

Can the hydraulic fluid level cause this? It has abou 1/2 " of fluid in the reservoir. What is the correct level?

Where is the best place to buy MB fluids like hydraulic, brake (are they the same), coolant, etc? The dealership?
