grinding or humming noise

I just noticed a humming or grinding noise when i drive, i have civic dx
manual tranny,127,000 miles,just had new boots and axles on,wheel bearing
and hub put on. so what could it be????i was thinking an alignment or
wheel balancing....

 

If you haven't had the manual transmission fluid replaced or checked
recently, now's the time. If you have the owner's manual it will have the
replacement interval in it. And if you don't know when it was, have it
replaced. It's reasonably priced, and far cheaper than gear or synchro
trouble.

If the noise showed up immediately after all the suspension work was done,
then I would take it back to the shop and have it inspected. It could be
related to the prior work or it could be something new.

i had a new clutch put in 2004 so i am guessing they put new tranny fluid
in it,so could it be my tranny, the noise does not go away when i put it
in neutral or when i shut off the car rolling down the road

 

so you dont think its the tranny like mike said???? i hope not. i got the
bearings and all done like 3-4 months ago

 

There are a lot of potential causes for a humming or grinding noise.
However, it's unlikely that a bad alignment or an out of balance wheel could
be one of them. Though if someone just had the suspension apart to do the
axles and wheel bearing then that's the first place I would start looking
absent any other information.

There is positively no way I can answer a question like this with confidence
over the internet without actually listening to the noise and also without a
great deal more information. For example, do you hear the noise at idle or
only when the car is moving? Does the noise change when you push the clutch
pedal down?

well i took it back its the bearing they are replacing it for me,and to
answer your question it only does it when the car is moving so its nothing
to do with the tranny
