Need help please...

[Sarah 350z]

Hi everyone,

I have had my 350z about two months now and I have fallen in love absolutely great cars.

 

However I have a problem, she has developed a knocking noise from the front passenger side it only makes the noise as the road gets a bit rough but it sounds awful and is getting louder. There is no noise on smooth roads motorways etc also no noise when turning corners all that is ok it is just when as I said the road gets a bit rough but it does sound bad :-(

 

So things that I have done:

 

Both drop links have been replaced with new ones.

I have replaced the suspension bushes

I have replaced the shock

 

Any other ideas as none of these have solved the problem?

 

My mechanic has completely stripped the car down and nothing is standing out.

 

My car is a 2004 GT blue with 36k (gorgeous colour I may add) :-)

 

I plan to keep this car for a very very long time and I'm a bit of a perfectionist as I'm sure all of you are too so any fed back will be greatly appreciated as I'd love to get this sorted as soon as possible.

 

Many thanks Sarah :-)

It's the banana bar Sarah ... a quick search will answer all

[Sarah 350z]

Is that the same as the banana arm?

If you have already replaced all the bushes including as Attak Z says, banana arm bush, it could still be a number of things. Without someone riding in it with you difficult to diagnose.

 

Exhaust?

Engine mount?

Loose battery?

Bottle of JD under seat?

+1 Sarah ... its very strange that having replaced everything you have that there is still a knocking... just a thought - you have checked the wheel arch liner hasn't lost a grommit?

Yep but it's usually the other end of the banana bar that fails first, and this necessitates renewal of the complete bar ... Zmanalex will sort it out for you I'm sure.

Just a wee update, after some great advise from ZMANALEX and getting some parts of him it was indeed the compression rod ball joint so thankfully all is fixed and I'm a happy girl again :-)
