Has anyone replaced their power steering pump on a 1500HD 6.0 liter with hydroboost brakes? I guess the 2500 and 2500HD would be the same. I have a slight whine when accelerating and I have narrowed it down to the pump. It steers fine and doesn't make noise when steering just accelerating. Any help would be appreciated!

 

I did a power steering flush today after finding a step by step procedure on a Duramax website. It is definitely quieter, but still can be heard faintly. I, like most people, am guilty of ignoring the power steering fluid replacement interval. With the hydroboost brakes it is a simple 30 minute procedure.

 

Thanks for the information. I was unaware about it, today only i will definitely do the power steering fluid replacement.
