anthonyb I think you are right.
I just had the flex discs changed not long ago and the noise is like wha-wha-wha...
I noticed that the metal bracket that bolts onto the flex disc coming from the differential has a really worn out bolt hole and I'm suspecting that this is the problem.
Is there a remedy for this? replace that piece?
Can it even be bought seperately? Or do I have to get a new differential?
Does the flex disc cause it? Mine are brand new, is there such a thing a defective flex discs?
I had to switch mine around and the noise still originates from the same place, so it's not directly from the flex disc.
HELP HELP HELP, this noise is killing me!
