My 07 (85k miles) does the same thing. It loudly pops and clunks (ball peen hammer on frame sound)(ball peen hammer on anvil sound). One set of noises is the knuckles in the cv joints of the axles, all 4 corners. Nissan acknowledges the clunks and cv joint problems, but until they break apart, nissan considers them serviceable. The next set of clunks on all four corners is the splines on the axle shafts where they go into the wheels. Nissan does not lube them from the factory so they start clunking at about 35k miles. Nissan has service bulletined some model years and specifies a grease application, but only if you press them. All other model years that have the problem, nissan just makes excuses and lies about. 133K part
#80078 permatex antiseize is what nissan recommends if you do it yourself. It is superior to all greases. You can test the clunks with an application of corrosion X to the splines where they enter the universals and wheels. If the clunks go away for a short time, you got it! And if you have the oem substandard universals in your drive shaft(s) with no grease fittings, and more than 35-50k miles, check those as well.
