2007 Peugeot 307 humming/rumble....the final fight

Surprised you now think the noise is coming from the front when you were always adamant that it was the o/s/r at fault .You would be better to ask the mechanic who advised you what is needed , as I dont honestly know what the intermediate bearing you refer to on the driveshaft is .Perhaps someone on forum knows more about this model / car and can help .

I think the chap was referring to the drive shaft bearing, which is called the intermediate bearing on the 307. The reason the guy thinks its coming from the front is because the noise is Cyclic, ie, it sounds like something is rubbing from a cyclindrical source. To me it sounds like amplified tyre noise, but the question is, amplified from where.

I have been trying to find a garage with one of these electronic ears (microphones) linked to a box of tricks and you sit in the passenger seat, switching between them whilst someone else drives, thus locating the source of the noise, but no-one in Scotland seems to have heard of it.

Really really frustrating that something so simple, cant be traced.

Anyway, I have bought myself one of these mechanical stethoscopes and will go over the car it whilst the wife drives and see if I can pinpoint it.

OK. Its now a year since this problem occurred and whilst I have pretty much accepted it, it is still there. I took my car down to get the front brake disks and pads changed as they were heavily corroded, and also to get Mudflaps fitted to the rear. Now remember I stated this noise was coming from the back??

After having the Brake Discs and Pads fitted along with the Mudflaps, the noise has changed somewhat and is a lot quieter.

What I want to know, is it likely to be the mudflaps or the brake disc that is muffling the noise, and if it is the brake disc, am I looking at a corroded bearing, rather than a busted one?
