are you guys braking hard? i always hear a distinct clunk when i press the brakes pretty hard. its just the ABS doing its thing i've always assumed. only happens when i brake quickly to a stop. ive taken apart most of my suspension/brakes and theres absolutely nothing wrong, and therefore doesnt even bother me anymore

woops, didnt realize this thread was a year old haha

I have a 2010 Z and it makes the same sound when i shift from park or if i speed up slow down. it is very annoying nice looking car but a lot of clicks, clanks and rattles.

that sounds more like symptoms of the dreaded axle click since it occurs to you when you load/unload the rear axles.
it sounds most like a metallic clicking noise but that's the most i can say without hearing it.

if it's really bad, it will click every time you accelerate and let go of the pedal, and also going from a forward gear to reverse and vice versa.
should be able to hear it driving next to a kerb with the windows down

i've eliminated all my cabin rattles.
i have tried to fix my axle click problem, even following the FSM but i think the torque spec for the nut is insufficient. currently have the right side done up to 115nm, left side is on the factory spec 105nm.

dude take off ur wheel, start tighening all the nuts and bolt, do not over tighten them just look for the one that is loose check all of em, on brakes on knuckles, on suspension might be undder tencion but it should be farely loose, and look for bad bushings that are worn also must be changed am shure u will find something. Gl:tup:

I also with a 2010 have a noise as this started at about 30,000 does it also by engaging and disengaging the clutch at low speeds I am bringing it in on Monday.
I believe it is from play in the splines

Rear clunk
 

i have a 2010 370z and it had a similar problem. Found a post some time ago for a 350 with the same problem there was a service bulletin issued by Nissan. I will see if I can find it. The problem was the rear drive shaft bolts were loose where it connects with the diff. The mechanic pulled the drive shafts and packed it with grease and tighten the bolts, no more click and clank from the rear end

Same issue, but Nissan refuse to cover under warranty with the TSB, so I just leaving it as is for now. there is a DIY post of how to fix it.

Any more updates on this?

This has been covered plenty before, the rear noise is the crossmember support for the rear diff that is banging against other mechanics under the car, the differential bushing fails and leaks fluid on the diff, impossible to miss, the dealer will replace the bushing and crossbar under warranty if this happens (Sometimes)

Had mine replaced about a month ago under warranty

What do you mean probably is has to do something with the parking brake adjustment?How can i check it?I also have exactly the same problem!

Due to the luck of shims?But you replaced them?How can this be the solution?Not stiff enough?
