new brakes.. it is definatly a speed thing,, not a pad ... it does fluctuate even at a steady speed.

Did they Bend the Backer plate? ( Rubbing on the Rotor )

Define "new brakes".

and.....is it snowing alot outside?

so far....."the bearing feels good"......ain't cutt'n it for diagnostic help.

but that bit about the brake job....... now there's some info. ~:~ MarshMonster ~sprinkles a little salt on his gumbo....sips his coffee..... wonders if yer noise was there before the brake job~

Power steering pump?

the sound doesnt happen every day or all the time, it is intermittent at best. backer plate would be all the time i would think, bearings?,, well, that was not a good diagnostic response, i am taking the truck to a 4 x 4 shop Monday morning, perhaps they can pic it out and remedy the problem. i'll post back if they find it. thanks guys.. phillip

======== ======== Sorry....but i'm focused on the brake job.

Was the noise there before the brake job??

The reason I asked about the snow was because of road salt possibly causing the noise.

Also.... i agree, the backing plate "should" cause the noise all the time.

any whooo..... let us know.

phil,

I too have a 96 Suburban 1500 (170k) w/ a whirring sound under the L/F side. There was no play in the bearing. I replaced the L/F bearing but still made the sound (sounds just like a bad bearing). I think that the carrier bearings in the front differential are worn and causing the noise. That is the only thing that we can come up with. I have not gotten around to checking it out yet. The noise really is noticable when the truck is coasting or w/ very little throttle...not there when under heavier acceleration. Good luck. Let me know if you find something out. I'll do the same.

it was a left wheel bearing, it is a sealed bearing and it was the seal that was sqeeling. Thanks for the input and replies. it's fixed and truck already sold. "I miss that Truck!"
