Shezad93 Posted June 16, 2015 Share Posted June 16, 2015 Hey Guys, I have 2004 350z with 72k Miles. There has been a rattling/knocking noise on my passenger side and slight vibrations can be felt when I have someone in the car with me. It seems to be mainly on un-even road surfaces and at low speeds. After reading the forum, I expected that it was the Compression rod (Banana Arm) or the bushes. So I booked it into my local mechanic and hoped for the best. However the mechanics took it for a spin and clearly heard the noise but whenever the car was on the ramp, everything apparently seemed fine, bushes, control arm, compression arm, shocks, ball joints, etc. With no movement whatsoever. The mechanic suggested that I drive it for another while and wait for it to get worse so it could be easier to diagnose or potentially book it into Nissan to have a look at, instead of purchasing a number of unnecessary parts. I have read that it is also undetectable to realise its the banana arm, so is it most likely it is that? One of the employees suggested it could maybe be the steering rack and another say maybe a shock? I can get a banana arm with a 12 month warranty online for £75 so should I just give it a try? A friend has also recommended a Nissan Specialist who does all the work on his R35 GTR who is 15 miles away to see if they could identify the problem! Thanks for the help!

PMX Posted June 16, 2015 Share Posted June 16, 2015 Take it to a Nissan specialist, ideally a 350z specialist! I had the same problem, asked my local garage to look at it (didn't have time to go to Cougar Store, who normally service my car) they couldn't find the fault (despite driving it, putting it on the ramp, etc) & suggested I just carry on driving the car until it got worst Then to bring it back in?? When I had a bit more time, I booked in into Cougar Store in Leicester, they diagnosed the fault straight away (compression/banana arm), they ordered the parts & fitted them a couple of weeks later. Job done, no more knocking Quote Link to comment Share on other sites More sharing options...
Zeezeebaba Posted June 16, 2015 Share Posted June 16, 2015 Same here. Mine had no movement on the ramp either. Changed both and all sorted. Also worth doing the droplinks at the same time for peace of mind. Quote Link to comment Share on other sites More sharing options...
ATTAK Z Posted June 16, 2015 Share Posted June 16, 2015 B A N A N A B A R ... don't waste your money on the cheap replacement - go for the Nissan OEM from one of the traders here ... it'll cost you £250.00 Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted June 16, 2015 Share Posted June 16, 2015 Certainly sounds like the compression rod ball joint. Compression rods and seating cones are in stock and good to go same /next day. Just drop me a PM if I can help further. Alex. Quote Link to comment Share on other sites More sharing options...
