Loud Droning Noise From Rear

[MC10]

Hi Guys,

I have a slight issue with my A3, I changed both rear wheel bearings a few months ago, infact all 4 were changed, BUT it has more or less 2 new bearing on the rear..yet..when I have people sit in the back I get the same deep droning noise as if the bearings are away again. The noise is slightly there when it's just me driving but certainly hear it when I have a full car. I changed the rear brakes also and swapped the bearings round to see if I had one faulty one..but noise is still there...very annoying! What else could this be...because there isn't much to narrow down to except the bearings AGAIN...but surely 2 cant be away. And its 100% the back as its always louder when people sit in the back....HELP

p.s sorry for the huge story, only way I could explain lol

Thanks

id change the front wheels to the rear and see if its the same.Ive had similar and it cured it...still dont know why but must have been a wheel with a fault or requiring way to much weight to balance

I had a similar problem.
cause= according the demon tweeks
the rear tyres were extremely over inflated past 50psi
which damages the tyre.
so when pressure was reduced to 32psi the drone started.
cure=i put good set of tyres on the rear.
have you bought or do you buy second hand tyres whose
history you have no pyor knowledge.

I put a pair of Enduro budget tyres on my Passat, and they sounded like an aeroplane taking off then I hit 35-40mph, which is the speed I use the most almost! Thought it was wheel bearings, since my car had covered almost 200k miles, but after 1500 miles, I got a puncture on my rear, so swopped the pair to Nankang NSII's, drone went instantly!

Still have a spare almost new Enduro in my garage! lol

I sometimes get a loud whining noise from the front passenger side, it stops when the missus gets out

Surely she should have been in the boot?

Sorry to be of no help but the title of this thread just made me think ... Ha wicked a thread about farts, but I was sad to find out it was about cars...
