Maybe climate control fan?

 

Check your brakes as well, if they're running low or the brake pad hardware is damaged causing the pad the touch the rotor when you're turning right.

 

thats interesting... why that?

 

Believe it or not I was getting a noise from the blower motor fan while only turning right! The way I figured it out is to completely turn off the climate control (fan to OFF, switch the mode off of auto on ECC). Presto the noise went away. Replaced the blower motor and the noise has not returned.

 

I pinpointed this to the right front ball joint on the A arm... there was also a slight tear in the CV boot so im replacing that as well... might have a busy day tomorrow with this..

 

Glad you finally tracked it down.

 

yeah its amazing how many things make noise on a volvo

 

AGREED

 

ok, here is the update.. still the same problem.

I dropped the volvo off at my local volvo guy and he was the one who diagnosed the ball joint and torn axle boot.
I replaced both on the passenger side, used a rebuild axle and new control arm, they were both bad!
I also got 4 new tires, balanced and alligned.
I drive several cars so I had not put any real miles on the volvo in a while.
Today the noise happened again, I dont think it ever went away actually.....

So I guess I'm back at square one... still the same noise, a metalic whirr.hum while turning right???
Possbly the driver side balljoint is bad as well? I just hate to start throwing parts at the car not knwoing whats going on.
I also cant see how its a hub bearing, both fo them were replaced less than 30K ago by the dealer and looked fine upon inspection.

Front struts are also only a year old.

My brakes do squeel a bit, but I never drove an older volvo that didnt.

Im fighting a loosing battle here... please chime in.[]

 

Greetings from Chicagoland.

Sorry to hear your problem, especially after spending $$$ to replace expensive Volvo parts. I think many of us have been there.

The hub bearing is probably ok, my 850 has 14,4000 miles with the original hubs and they are still fine.

Have you checked the power steering for fluid level and any leak from the rack boots, as well as the condition of serpentine belt? How about upper strut mounts/spring seats?

I once had a loose bumper bolt and the car was making high-pitch noise (sort of like little birds singing).

I wish you luck in finding the actual culprit.

Hi! I am from Spain and drive a '98 V70 T5 (mechanically same as a 850). I have found this post due to a extrange noise I am also having when turning right. I will try to describe the sound:

-It is like a.. TTZTZTZZTZTZTZ
-It sometimes sounds continous (TZTZTZTZZZTTZZTZ), and other times just "chopped" (TZTZ TTZ TZTZTZZT)
-It does not sound "mechanical", it is speed independent, its pitch/frecuency/tone does not change with vehicle speed
-It only sounds when turning right
-I believe that it only sounds after pushing the engine quite hard
-It looks like being linked someway to the turbo air aspirating sound.


Does this match your sound rejeep ? is your car a turbo ?

 

no,
being related to speed I feel like your noise would be the tires rubbin on something..
mine is deff a metalic sound.. metal against metal.
Is has stopped with a lot in its frequnecy, but its till there when turning right.
im convinced its something in the suspention.. might be the other ball joint, bu the mechanic said that the driver side was fine.
only other thing, could it be the brakes?
I have pleanly of matirial left on mine, but they do suqeel something fierce.

 

mine is not speed related..

 

brake dust shield hitting something...?
no mine is not turbo

 

Is it loud or soft?

 

no its fairly loud...
Im starting to think it might be comming form the rear wheels...?
I also can faintly hear it when tracking strait down the road sometimes...
