humming sound.....
hi guys i just got my car maintained by my mechanic. i had the fluids change to royal purlple on the tranny,engine and differential after i got the car i made a 120km drive and the car is ok then a day after i was driving the car for like 50kms i began to hear a humming sound so i turned the radio off and listened to the humm sound... whenever i go fast the humming gets louder when i go slow it the sound gets lower... i tried to listen where its coming from based on my inspection and observation its coming from my tranny or engine or propeler i tried to put the car in neutral then let it roll down a hill the humming is there even not in gears.... what could be the problem and whats the solution for this problem?? thanks!! is this bad???? will this brake my engine??? sorry noob here
i dont hear the humming from the rear i hear it likes its in the middle... the tranny or propler....... thanks!!!

humming doesn't really say much...
doesn't sound like a problem...if it's only a slight humm...
perhaps a sound clip?
what is the weight of the royal purple diff oil...a hunch tells me its not correct...

you can immediately flush your diff fluid with le-607 (or the new replacement).
that's one option.
if the humming is present when you're in neutral, i doubt it has anything to do with the engine...and more likely the drivetrain.
sheet...it could be anything at this point.
have your mechanic pinpoint the sound...
too difficult for online pinpointing of a humming sound related to the entire drivetrain...
that's one option.
