When I take turns especialy tight turns I can hear a clunk or a knock. Sounds just like something in the luggage compartment that slid over and hit the side. Ive checked the lug nuts and they are tight also ive checked the spare and it is tightly secured. The mufflers are not moving either. What is the noise comming from? :nonod: It is scaring me. :chevy

Sounds like you need to replace your differental fluid and posi additive use the oils from GM its the best for this. The sound that you have is from the clutch packs in your rear differental when in a turn the clutches slip the two rear wheel rotate independent, some what of each other. The oil and additive allow this. If the oil and additive have degraded then the chatter is what happens when the clutch packs stick. pjo

Since it's in turns and not on acceleration, I'm thinking pumpkin. If it were a groaning kind of sound, I'd say posi fluid, but for a clunk you might have something else going on.
