Nissan 370Z Forum - View Single Post - Front end temp dependent noise troubleshooting

Hey guys, I really need a hand figuring out where to start with this one. So on start up with the engine cold I have zero issues. However once up to temperature and driving for ~30-40mins I can hear a clunking-ish noise from the front end.

From what I've found,
it is not engine rpm related,
It is not consistently wheel rotation related,
Noise only happens when up to temp (190F+)
I can not replicate the sound out side of the car by forcing the front end to bounce,
The noise is from the front end but I can't localize it to driver or passenger side.

It sounds like a damaged CV shaft / boot or damaged wheel bearing. But I've never dealt with either of these being temperature dependent.

Mods- ksport Kontrol pro coilovers (verified all fasteners tight), spc camber arms.

The sound came out of nowhere. I had not done any maintenance or modifications within the month of the noise starting.

Brought the car into Nissan and they said "there were too many aftermarket parts for them to know what was going on" so no help there.

Any ideas or help at all would be greatly appreciated! Thanks in advance guys!
