Hi folks.
I have a dronning, humming noise coming from the rear of my 2.5 V6 Estate.
Suspects are wheel bearing, drive shaft, diff or prop shaft.
Noise is at all speeds, louder the faster you go, but the noise does go away when i take a left hand bend at speed then comes back when i straighten up.
So the noise goes when the weight of the car is on the drivers side.
Is their a common fault on these for the noise or is their something else i should be looking for.
All comments and help much appreciated.

sounds like a wheel bearing

Had a similar problem on the front. As I eventually replaced both front  hubs at about £80 a piece., to no effect. I would try swopping tyres front to back before I got too excited!

The ones causing my problems were Firestone which on removal to the back fixed the problem. I later swapped them diagonally to the front  again so that they turned in the opposite direction, no problems since then !

I had similar Swopped tyres front to back still the same put new tyres on front problem 90% cured.

If it is wheel bearing would this bearing show more heat than the other

Hi Jiho,

Be careful when diagnosing this, as  sounds travel from front to back and vice versa.

I changed  a front Universal Joint on my Cavalier as the noise was coming from the front footwell.....but

that Didnt fix it !!
So decided to live with a  faulty gearbox.....wrong again !!

2 weeks later  drone from rear  suggested rear wheel bearings, so swapped both with used /nearly new bearings....and voila ..all was sorted .....sound was travelling to the front through the chassis.

On a more positive note, i have had 2 cars with droning back ends, which i eventually fixed ( 72 ford cortina +  69 Ford Falcon)
Both were rear wheel drive, and both  had worn out  hardy spicer couplings on the back of the  propshaft.

I would suggest that you check  the rear U.J.  on the propshaft, as it  runs dryer than the front one, and the bearings dry up and  dont run properly. on all rear wheel drives.
swapping  prop shaft with a good second hand one may sort it !!...and its easy to do .

I wouldn,t  suspect the diff, as  it would/could  clunk as well as drone.

difficult to diagnose without hearing  but wheel bearings  could  do the same, but check  prop shaft first, then bearings i would suggest, especially with  the V6 which supplies a lot of torque through the prop shaft (single bearing that drives the whole lot. )

let us know how you get on

droning noise is often the tyres - on my Signum thought we had wheel bearing issues as noise was so loud - but changed tyres and no problems at all now.
