Speed bump suspension creak

Hi Guys,

 

Reckon i've got a bit of a problem with my Z - In the morning when i set off the suspension makes a creak\sqeaky noise when going over the slightest of bumps - that seems to settle down after a mile or so until I can't hear it in the cabin - however after that any speed bump i go over makes a LOUD creak - makes the car sound like an old banger.

 

The car is in the garage just now (A Glasgow Nissan high performance centre - the place I bought the thing from a couple of months ago - who have been incredibly frustrating to deal with over warranty issues - ranging from blaming me for damage to a lower suspension arm bush & damaged engine undertray after owning the car for 2 weeks and taking a month of coming and going to find a worn "top mount" that was banging away) - as per usual they are claiming there is no issue (except admitting they did hear a slight noise as well - numpties).

 

A quick google suggests banana arm bushes, and the US 350z forum suggests perhaps an engine mount - but reading around suggests the banana arm bushes are a common failure.

 

Any suggestions from you guys? I've uploaded a video to youtube with the noise -

That's some weird noises! Probably banana arm, but sounds a lot worse than mine. Didn't realize there was a Nissan high performance center in Glasgow? Only one I know of is Edinburgh. Take it to infinity Glasgow, they recently fixed someones on here.

Unfortunately\Fortunately I've got a warranty on the car (only had it just under 3 months) - it won't be going back to them once that expires - it'll be off to infiniti. But yeah Macklin Nissan in Darnley are a High Performance Centre, they have a certified Master Nissan Mechanic - who seems good but I keep getting other mechanics and then have to hassle the garage until Ian (the master mechanic) takes a look and finds something. *sigh*

 

Don't think the car has been lowered - the drop links were replaced 2 months ago to try and combat a banging noise.

I'd suggest your drop links are knackered. There are a few you tube video's that you can check out. Just type "350Z drop links" and you'll find that the noise made by your Zed is pretty much the same as on the videos. They're pretty simple to fix.
