I have an Auburn that I recently installed and yes mine does it too. The differential is a hard locking one that really does not want to unlock, but does when it has to. I have changed various fluids and it still grinds/clunks. This is normal even though it saounds horrible.

good to hear ive went from sythetic fluid back to regual rearend fluid and it does it either way im relieved thanks Ron

Oh good, I just had one of these put in recently, and it does that alot. I though they screwed up putting it in or it was faulty. Hooks nicely though.
