LLY: Humming after deceleration?

[cstephens93]

What is the consensus on 2005 LLY humming after extended highway driving?

Ex: Driving for a few hours on the highway, then slowing down to get on the exit ramp and a large amount of humming or droning can be heard? Like the sound when you are low on PS fluid but you're just driving straight and not turning.

Is this normal in all 05 models? I have seen other threads mentioning it but havent found a "fix" yet even when replacing the pump or hydroboost...

Is the humming off-key?

It's pretty off-key if I do say so myself...

My old dodge did that. Rear was low on fluid. Did you check the obvious maintenance shit ?

Yeah I have checked. I do know that I have a small leak somewhere with PS fluid...but I dont know how the humming happens even when the PS fluid is full.

It's literally just whenever I drive on the highway for a long time and decelerate on the exit ramp
