    Noise difference between bad center bearing,wheel bearing...

    rear differential or torn half shaft cv boots?

    I have a wub wub wub wub wub type of noise that is speed related and not rpm related.
    Its coming from the rear and is unbearable loud. Doesnt change when in gear or not.

    I narrowed it down to these problems. Any help would be great

    wheel bearing noises will change depending on which way you turn, if the noise stays the same under all conditions i'd suspect the center support bearing and axles...

        From my experiance is that when the center bearing fail's there will be a vibration that is RPM dependent that originates from the center consol, From what other people have told me is that the rubber surround fails before the acctual bearing fails. . when I found out that i had to do mine is after i had just got done doin a clutch job so i had to rip it all apart again great hu!
