Its one of your accumulators, and I'm betting the Front, cheap easy fix, did mine, and while I was at it did both front and rear.

Thanks cadbob, I was thinking the same.When you replaced the air cell on the front valve block was there any fluid loss when you unscrewed it, and how long did it take.

The Diaphragm was shot, the Nitrogen ball was filled with Black Fluid, the rest of the system was Green thank god.
Even the Mechanic who did job for me thought it was ABC Pump i said noway its pump and told him to think of his house plumbing, the house pumps from well (ABC Pump) but the Pressure Comes from the Bladder Tank (Accumulators)
It started get worse on the dips and bumps, after the replacement, I took back road home that was full of dips and bumps!
