Hi folks, Time.... far from this useful forum.

I please require your help, while driving at 90 ~ 120 kph (56 ~ 75 mph) or more, if I'm driving thru a slight curve to the left and turn the gear to the left, but slightly, i hear a BRRRRRRRRR sound, with a hardly noticeable vibration. If i drive slower than that, I cannot notice it.

The car is a Forester 2017, with 57000kms (35000miles).

I thought It could be tire alignment or balance (or even rotation). But that noise is getting me sad.

Please take a look at the small video I recorded. The noise is at second 2 aprox.

Your advices thanks.

I can hear the noise readily at 2 seconds in the (good) video, but have no experience to suggest cause of the noise. In general high speed (60 mph) steering wheel vibrations are tires out of balance, but I've never heard such a noise, but don't know what tire de-lamination could sound like.

Why not take car back to where you bought the tires and describe problem and ask for their diagnosis. Where I am the tire stores do pretty decent free rebalances or diagnoses for customers. Doesn't mean you have to have it fixed that day ... If they're original tires, go to the tire store you're likely to use for replacement tires.

Luck. Post up what it is - whenever you get it figured out.

As @UhOh suggests above, professional tire shops are pretty good about diagnosing these types of noises. Unfortunately it can be very difficult to trouble-shoot via the internet. Don't go to a big-box store; they generally don't have the expertise and have liability policies in place that prevent them from attempting to diagnose problems that require driving the car.

What's "WAG"?

Should CV joint sound like that only at high speed? (higher than 90 ~ 120 kph (56 ~ 75 mph))? or even at low speed?

WAG May mean Wild A** Guess.

My guess would be a wheel bearing or a tire with a severe wear problem, maybe internal tread separation. But as CoolMike pointed out. It is hard to tell with such a short audio clip. At the very least I would carefully inspect the tires and suspension for wear and damage, especially from the advantage point of a chassis lift.

Thanks people for your suggestions about this issue. Yesterday I carried the forester to the dealer and just with a 1 minute test driving and accelerating fast while turning the gear. The mechanic found that it was the "bushings". "front control arm bushing" or something. Problem is fixed thanks God.

Damn, I didnt expected to be damaged (or little damaged) at only 35000 miles of use (no offroad, some holes in the road but nothing really bad).

The cost was about 196.00 (he suggested change both, left and right). There were supposed to be 2 for each side.

10.00 x 2
19.00 x 2
90.00 labor
36.00 tires alignment, balance and rotation

Are those bushing that weak to be damaged in only 2 years and a half?

Also, I heard that the polyurethane bushing are the best.

Thanks again folks
