Ya I was think wheel bearings too but it's not making any other signs like most do...(excessive noise at all rpms/mphs..and I have no play in the wheels).

Im still on the brakes honestly, I've noticed that when my pedal gets stiff the car starts this bullshit. So the other day when it started, I pulled over and popped the hood. Pulled the line off the booster and plugged it back in. Brakes went back to normal. I know there's a external check valve on the firewall above the booster and I blew threw that and it works. My question is there another check valve internally in the booster?

Long behold the fucking rotors.......god dammit

so it was the rotors then?

ya it was the rotors.......im sorry cre i didnt listen sooner lol,
i was on alldata and a TSB popped up about drivetrain vibration and described my problems almost 100%. New rotors on and its been fine. Im blown away........

im no where near as savy as cre but i got this one right yay:D

well not to burst your bubble, but the vibration is back after a nice few days of smooth driving. the pedal got stiff again and it started. guess im back to the booster. shit....
:dunno:

ill get it right eventualy lol. thats sucks man any idea how much a new or factory rebuilt one will be?

i can get one from my job with my discount for about 130 w/o core. thats not too bad. just wish i knew someone who could let me borrow:bow: theres to test it.

Did you ever get this resolved?

Sorry haven't updated this. Working alot. So....
-New booster and Aisin master installed. Vibration came back. Again...

I replaced the shitty brakes. I had AutoZone basic pads(that's all they make for our cars incase you didn't know). They were cracked all the way to the metal
Got some Wagner pads from O'Reillys.
I hate to say this cause, when I do it comes back. Im on three days of driving. No vibration. :bow:
