Howling while driving.. already did wheelbearing

[S4evr]

when i switched over to my summer wheels this spring, i noticed that there is a loud howling sound coming from the front of the car while driving. Upon deaccelerating, i get a small vibration that feels like it is coming from the front wheels (vibration changes with speed) I thought it was my wheelbearing, so i replaced my passenger front last week, didnt do anything. i am replacing driver front this week to see if it goes away, but wanted your opinion to see if it may be something else. Initial thought after i replaced first bearing was maybe tire noise? they are cheapish tires (wanli s1088) and i noticed some extra wear on the inner side of the tire so perhaps this was the cause? Secondly.. my CV? a couple of months ago (right before winter) the inside of my wheel KEPT getting dirty and greasy.. i thought nothing of it until i switched over to my winter wheels when i saw that my cv boot on the passanger side was torn open. upon realizing this i started banging my head because i had driven close to 600 miles with it torn open (to and from boston and rochester ny) i immediatly got it fixed and no problems seemed to have occured until now. could a damaged cv cause this howl at all speeds and small vibration during low speed deacceleration?

I drove on a torn CV boot for FAR longer than 600 miles on my A6. I never had any howling. I wouldn't think that is the problem.

Check the brakes?

what part of the brake system would cause howling?

[j_korteS4]

I just had both of my front axles replaced a coupe days ago because of torn CV's. It didn't cause any howling though.

I was thinking if maybe one of the pads was rubbing the rotor wrong it might make some noise, but maybe not "howling" as you describe it.

[S4evr]

^rubbing pads would make a low grinding noise, ive heard it before.

would lack of alignment cause howling?

My vote is tires. I have cheap wearing tires that are wore more on inside and they howl like the wind.

^beat me to it.
what type of tires do you have? i had kdw's and after the half way mark on wear n tear they begin screaming. its unbearable.

Wanli S1088

very hard choppy tires tend to make noise and it wont stop sounds like a wheel bearing or diff or something blowing up.

I agree with tires. Mine howl like mad.

Try switching back to your winter's for a day and see if the noise goes away.

restating the obvious. if its not a wheel bearing the only other noise that could cause a howling as speed increases would be tires.
