Hey Guys,

this winter I decided to free the underbody of my 350z from rust and disassembled EVERYTHING and so I took the chance to install some new parts while putting everything back together.
I installed the Z1 subframe bushing collars, Bell Raceworks diff brace and Z1 adjustable rear toe arms.
But now I have a really annoying, clunking noise while driving slow from the rear, nothing to hear when driving faster than ~15mp/h and I can't figure out what it is.
I tightened everything to spec, even doubled checked it, cant find any part that is loose or doing sounds when I shake it etc.
Could it be "normal" for the subframe collars or diff brace?
Sorry if my english is hard to understand some times, greetings from germany.

Maybe "rear axle click"? https://my350z.com/forum/engine-driv...rear-axle.html

Definetely not, sounds way different and deeper. Got a feeling that there's something not right with the bushing collars but no idea how to check it.

Does the toe arms have bushings or heim joints?

Bushings.

It's the diff brace IMO. I have noticed a subtle clunk since I installed the Gktech brace on my Z, this noise is only observed at idle/creep speeds while in 1st gear (going through a parking garage with speed bumps for example). If it's not much trouble, I would remove the Bell Raceworks brace and try to reproduce the clunking.
Cheers!

Yeah, that was just literally my thought 5 minutes ago and what i'll try out tomorrow.

Just tested it, wasn't the problem unfortunately.
But i wonder if that gap right there is supposed to be so big...
