john give me your tranny man. j/k What i think it was, was when i bought the car it had to different tires on it, a lower profile tires in the front and a taller tre in the back. drove around like this for at leasr 4 months until i read that different tires like that would kill your center diff. And about 3 to 4 months ago it seemed like i had a welded center diff then one day making a u turn the back tire wasnt chirping any more like it did when i got the car. so i kind figured it was on its last days and that was before i bought your clutch from you john. but i dlo love that clutch thou.
