#6 of 14 Rumbling noise in the back of 305Z roadster by cantgo55 Jul 28, 2007 (4:51 am)
Hello all,   I bought my 2006 350Z touring roadster in Nov 2005. I have been very happy with this car up until now. For the past two months, every time I pull into my driveway, I can hear a rumbling noise in the back of the car for a few seconds. The way I pull into my driveway is like this. As the car approaches the driveway, I slow down enough to almost a complete stop, and put it back in first gear as I turn into the driveway. Then I slowly accelerate while in first gear to make it over the curb. My driveway is on a bit of a downward incline. As soon as the front of the car makes it past the sidewalk, I can hear the low rumbling noise in the back. At this point the car is rolling on a downward incline in first gear. It appears that the rumbling noise is only heard while in first gear and on a downward incline. No noise while backing out of the driveway in reverse gear.    Took it to Nissan dealer but they could not replicate the noise. The mechanic found the tire changing kit not strapped down and blame it for the noise problem. But I can produce the noise consistently at home, even with the tire changing kit strapped down. The spare tire is also tightly strapped down.    If anyone knows what is causing the rumbling noise please let me know. You can send me an email at simonlnguyenyahoo.com. Many thanks in advance.

Replying to: cantgo55 (Jul 28, 2007 4:51 am) Is it possible this is the stability control kicking in? If the car is canted as you turn into the driveway, one of the rear tires is lifting up and activated the traction/stab control. This would then sound like a rumble or some type of racket in the rear of the car. Try turning off the stab control before entering the drive. Replies to this message: cantgo55 (Jul 30, 2007 6:09 pm)

dat2,   I turned off TCS and it appears that the noise went away. I turned on TCS and also did not hear the noise again. So it is possible that turn TCS off and on reset something? Thanks a lot for your help. Replies to this message: dat2 (Aug 05, 2007 5:42 pm) kala (Aug 11, 2007 1:03 am)

Replying to: cantgo55 (Aug 01, 2007 2:11 pm) Yes, I think you reset it, it is probably just the TCS/stability control kicking in. Good luck!!

Replying to: cantgo55 (Aug 01, 2007 2:11 pm) If the rumbling sound returns check my reply under "Nissan 350Z: Transmission Questions." The cause could be as simple as something loose in one of your storage compartments.
#12 of 14 my nissan 03 by 03nissan Oct 05, 2007 (11:59 pm)
i have an 03 nissan. i like racing it but since i got it, it doesnt do any good. i hear a noise when i hit holes on the road like if something is loose. sounds like if the exhaust is hitting or if i have something in my trunk. but its none of those its been like tripled checked and like if it had a voodoo spell on it bcuz they cant find these annoying rattling sounds. my stock engine would do 14.5 seconds at quarter mile. i installed an hks ehaust, stainless steel headers, an AEM intake sytem and a high performance clutch kit. and now im doing 15 seconds when i should be like on the 13's or something lower than 14.5 of course. anyone can help? when im on idle theres a rattling sound. and at the rear end like if my exhaust rattles or if its shaking. i have warranty at the performance shop and everything was guranteed and double checked twice. what can i do? i cant blame it on the racing parts because it would do the same stock way b4 i got into racing. i just thought trying to modify it from stock would help. but i need help. i love my nissan and its really putting me down

Replying to: heronm (Apr 26, 2006 6:06 am) hi, i have 2003 350z as well and i had the same problem, i did my homework and found that 2003-2005 Zs have a rear bearing problem. I had the right side done at 48k and now the left side is making the same noise. u need to have the bearings replaced in the rear axel. i suggest u replace both sides at the same time. the dealership wouldnt cover both sides at the time when it was under warrenty and now i to replace the drivers side myself. if u wanna comfirm u have the same problem. put ur in reverse, hold down the break firmly, and tap the gas, if u here the clicking noise this is ur problem. hope that helps...btw it cost a about 300 or so to get it fixed.

Replying to: htbeemer (Jul 10, 2009 9:42 am) one other note i was online and found a tech forum for nissan, the tech is saying the axle needs to be greased. this what the tech says the repair is for clicking noises in the rear. from what i seen, u need take off the rear axle use a special grease and replace a flange and the hardware to the flange and then put it all back together.
