I posted earlier about Annoying vibration, but it does not happen at all time. It only happens once aweek. The vibration makes me feel like the front end tires is getting flat even the road surface is smooth. It tooks me a day to think back the history work done that I have worked on the car and realized that this front end may have something to do with Steering fuid changed in the past. I flushed the steering fluid with instruction of VMF posted here and included with 6 bottles of Syn Power Steering fluid. At the end, I filled the fluild up to right above HOT measuring stick. I was not sure how much bubbles still left in the pump so I left it as it for the past two months.
This morning, it seems like the fluid getting lower, it barely touches the tip of the dip stick. Is this mean most of the bubbles are gone from the pump? I try to measure the fluid before and after started the engine but still there is no different with the measurement.
