DeeVee, Does the additive need to actually soak into the clutches-like after a differential rebuild? And are you saying that w/ a differential that's been run for years, the clutches could go dry (as far as not having the correct/not enoughadditive) and cause that chatter?
*****After writing here, I went back as I questioned the specifics of my answer(s) due to your answer. Like a "skimming" idiot, I never read that the rear had JUST been gone through, and assumed it had miles on it. Now my question is this: DeeVee, Have you ever seen it recommended that one should coat or soak the clutch pack in the additive prior to installation?
Haven't skimmed an article that terribly in quite awhile. Sorry f/ wasting everyone's time.

The clutches are simply prone to chattering until they get lubed up enough or break in - or break - period. I have seen some pretty discouraging pictures of the inferior clutches. I would think that applying posi lube and/or additive to the clutches during assembly certainly could not hurt!

As far as skimming goes - I do it too - all the time - but I do re-read a post before I post an answer.

The carbon fiber clutches supplied with most rebuild kits are junk, but that is what I have in my rear. I found (on another forum) that there are solid clutches available that are superior to the carbon fiber ones.

Thanks for your interest and reply. Like you, I think its the posi clutches, but you would think after the figure 8 in the parking lot trick and a few hundred miles on the e-way the dumb thing would be lubricated. It still does it after 400 miles

As for the "skimming," I did admit to it and didn't just "let it ride." So you skim and then read? OK. You're better than me. I do admit when I'm at fault. Hope I didn't ruffle anyone-else's panties. [8D] I meanthat in a nice way.

Might try another bottle of GM's posi lube additive. Can't hurt.

RE: rear end noise and air conditioning
My time to read posts completely and comprehend it all will come when I sell one of the houses and by a BIG garage w/ a small house attached, something I've truely wanted for a very long time. Ofcourse I'll probably have to dump, or will be dumped first by, the family. LOL Then I can have a small room for an office, just for my automotive hobbies, and a monster bay for the projects themselves. The house will consist of a kitchen, bathroom, and combined bedroom/living room/hang-out for the cat and dog. (Cat and dog will be taken for weekly baths so the room stays smelling good and not be allowedon the furniture.) Pets are allowed as they are loyal, unlike most people. LOL This MUST be rewarded. I'll then train them in time to hand me tools and do some light office work, and possibly some clean-up. Everyone else can either stay or hit the road. Come along for the ride if ya' want to. Then, I'll read all these posts completely, w/o fail, I promise.

Weekly baths? Count me in!
I agree with you TJ. I am also considering selling my large house and downsizing. But I do want one with a big GARAGE and our 5 dogs can stay too.

Monica! I am glad to hear that the chatter has worked itself out. Well done!
