Humming Noise coming from drive line!!

Postby LORD-GRAVEL » Sat Oct 24, 2020 7:48 pm

Hello all,
I have a 2007 Subaru Liberty 2.5 Automatic, have loved the car but a few weeks ago a humming noise started.

The noise only appears when about 60km and gets louder as you speed up.
Completely Speed related - does not change with the engine revs.
I have put the car up onto stands and the noise seems to be coming from the gearbox region.

it is not any of the wheel bears as I have replaced all of them.

in short, I am at the point of just getting another gearbox to see if it will stop the noise.

has anyone had any experiences with this?

Try a site specific google search, you’re unlikely to be the first with this issue:

https://www.google.com.au/search?sxsrf= ... =278&dpr=2

Here’s an example search with a couple of promising hits, feel free to refine the search keywords to see more results.

For an even larger user base, repeat the search on Eg LGT and other forums, here’s another example:

the tyres are fairly new (less than 10k on them) it didn't make the noise before a few weeks ago.

I have looked on most of the Subaru forums, but every case of a similar sound is always on an MT box, not an auto box. a mate told me to check the tail shaft for any movement in the centre bearing. so I will be doing that today.
