Volvo xc90 prop shaft noise
 
Hello I'm a bit lost in this case. I've read a lot of forums about similar cases, but no one seems spot on. By reading I've come to some possibilities what's wrong. Grease in cv joints hardened, support bearing, lower and upper motor mount, belt tensioner bearing, wheel bearing, front drive shafts.
So here's my problem:

Volvo Xc90 D5 AWD 185hp 2006 123000 km

CV joints at both ends of the propeller shaft has recently been greased up , but still the same noise between 35-50 mph / 60-80 km / h and from 1600 to 1800 rpm.
The sound sounds like a rumbling along with a ring. Subsequent throttle speed. The sound disappears when accelerating or gas reduction.
Have checked the heat shields along the shaft , top motor mount. but the most reasonable seems as if something is moving / spinning that creates the sound.
Anyone know what could cause this noise?
Any help would be gratefully received .
The sound makes me crazy !!!

There was a mod at one time to replace the rear flange for one with a vibration damper on it,

It was for a driveline noise around 50mph but carn't remember what year cars it was for altho might be worth checking to see if it has a damper fitted,

Its where the 6 bolts that hold the prop on to the haldex unit, if it looks like the front connection it hasn't got one if its massive with rubber inside it then it already has it

Update:
 
Today I was with the car to the garage and took off the prop shaft. Ringer noise disappeared, but a kind of roar/vibrating rumble of the motor at the same load as before. ringer noise is most likely carrier bearing. I desided i want to replace prop shaft and upper engine mount and lower right engine mount. At least I'll get assessed the status of the motor mounts. I have read that these can be one of the causes of engine roar I hear. My biggest fear is now that the ringer noise will reappear after i replaced the propshaft. est cost atleast 1500 in Norway at volvo dealer:err:

Did you manage to locate the problem?

I seem to have a simmilar issue - a rumble/vibrating sound from 1600-1800 RPM, only noticable in 5th and 6th gear at around 80km/h, Under 60km/h and over 100km/h its ok. It is also OK at 80 in 4th gear (over 2k RPM).

I noticed the sound goes away immediately if I press the brake pedal a little. :err:

May help?
 
Just wanted to help all the people who have had issues with the transmission or weird vibration noises from under the car. I have an XC90 2010. I bought it 6 months ago from a dealer and took out an extended 3 year warranty ( thank god). The car had very low mileage 35,000. Been driven by an old chap to the shops and back.

Anyway about 4 months ago I noticed a weird noise when I got to 5th Gear at 2200 revs. It sounded like a weird vibration noise almost like an exhaust sound/ grating noise. Almost like the noise when you have a hole in your exhaust. My first thought was the catalytic converter going. I took it into the dealer and they said it was an engine mounting and same thing again. At same time the AWD light came up saying not working. It went back in and as the car had been sitting for a few year not doing anything the filters in the Haldex Pump had clogged up.

Finally to car in last week and they had it for a week and have diagnosed the problem as being the drive shaft dampers worn out causing the drive shaft to oscillate at certain revs or between gears. They have just fitted a new drive shaft and dampers kit and it seems to be fixed. Total cost for new prop/ drive shaft plus labour about 600. Warranty covered the lot and now the car seems really responsive. Hopefully that will be the end of it. Hope that helps

Options to remove propshaft noise
 
i have a XC90 2011 with 100K on the clock. Had this clunking sound for around 18 months now and seems to be getting worse.
Taken car to Volvo specialist and he has outlined that the propshaft is worn at the joints and will need to be renewed ~1500!

Has anyone got any comments on what alternatives thee may be out there to cure this? Have heard that the propshaft could be effectively removed from the car which would make it just a FWD car rather than AWD.

Keen to understand the pros and cons

Thanks all

There are 3 joints on the propshaft .

The front and rear are easily replaced at home and the cost is about 50 each end for a good quality replacement.

The centre one is a different matter and not a DIY job but I understand that there are now propshaft specialists that can replace that one.

I would not be paying 1500 for a replacement shaft though.👍

Regarding running in 2WD without the propshaft - I'm struggling to locate a whine at present on my 2005 D5 auto XC90 and have removed the propshaft to eliminate it from my enquiries . . . my whine is still there, but the car drives fine (perhaps slightly better) with no warning lights or issues showing. If the front wheels were to lose traction, I guess the Haldex coupling would engage as normal but with no prop, the rear wheels wouldn't be driven to help out.

Have you told your insurance company? The AWD system is a key part of the overall DSTC, traction control etc.?

In reality the risk of anything happening is small but the consequences (either injury or financial) could be anything but....
