Hi Guys,
Working on our M998 Hmmwv project. Steering pump was noisy (loud humming/buzzing sound)& Hose going to fan control soleniod was vibrating badly. Replaced old steering pump with new rebuilt GM Core (this is the integral tank style pump). Primed and bled the system per TM's.
Still getting the annoying loud hum/buzz sound you can hear while driving (not like I can turn the radio up!). Checked the tank - no foam, don't think there is air in the system still? I have done the steering exercises several days in a row now and can't get rid of the **** hum!
Wondering if it maybe is supposed to be there? I'm not military and have no experience around these vehicles when they are in good shape. Wondering if it could be my fan control solenoid?
Thought about flushing the system and going with PS fluid instead of Dexron III that I used after searching around on SS. Thought I would ask for thoughts/opinions before I dump 6qt thru it though.
Thanks in advance!
