Rear Axle Clunk (Please Report Here!)

Buddy, you are beating a dead horse. Besides they are real hard on newbs here. Also there's a lot of cliquing between members so if you keep talking about it they are going to gang up on you and eat you alive.
Get the axle greased. Then drive it. Worst case scenario, it will need grease in 3 or 4 years. The Z is one of the most reliable sports cars out there.
I've owned quite a few nissans. They all have quirks. They all have something going on that's alarming compared to other brands. I had a 98 altima with tranny jump. I would put it in gear and it would pop. Took it to 3 mechanics. They couldn't find anything. I had a 240sx that did the same thing. I sold the 240sx before I could even care. But the altima, I was keeping so I checked it out. The mechanic told me some wise words that hold true 3 more nissans later. He said "In all the years I worked on nissans, they have quirks I can't exxplain, weird abnormalities, but they will never break down." Out of 5 nissans, and probably a combined million miles. I had one breakdown on the alternator on the 98 altima. Nothing else. You will get used to your car. I don't have a Z yet, I have a G which shares most components minus some extra peformance parts and short chassis.
I'm sure you will be ok. Just get some grease bro.

Well guys I have this clunk that just developed as well. Before any of the locals try to flame me as a newbie or some turnip wagon ballast let me state the following. One until about 3 years ago I was an L-1 certified ASE autotech, I have built and driven more cars than no doubt 85% of those on this forum, and grew up in a prototype aerospace machine shop.
When it comes to tolerances and proper operation I think I can safely say that I have a pretty damn good grasp on things. This noise is what makes you lean directly to the typical U-joint or ring and pinion slack. Of course our independent suspension gives us the option of CV shafts as well.
Regardless, don't let anyone tell you that this is acceptable. It is a sign of wear and loss of operable tolerances. I have just over 7,000 miles on my Z and don't drive it hard. This is unacceptable and only going to get worse.
Reading here and listening to some of these guys bash others for being concerned and happily driving their cars while destroying parts of them is enough to make me turn a deaf ear.
If some of you want to leave it and sound like your driving on square tires because your car isn't a rolls royce go ahead. I would rather have mine in proper operating order.

P.S. It goes to the dealer in the A.M.

Thanks for your comment ZeeRay. At least there's someone out there that sees my reasoning and understands where I'm coming from. I've pretty much given up on this thread at this point because everyone "knows it all" and just wants to rip your head off for posting a concern.

P.S. I still havent been back to my dealer yet to have the axle greased... as I'm still hesitant of doing it if it's only a temporary fix just to "quiet down" the noise. But if you could please either post back up or even PM me what your dealers says about your car's situation, that would be great!! Thanks
