Hello all, newbie here,just found this forum and as proud owner of a used 4 door............WOW things were great until about a month after takeing ownership.The unit started to have vibration trouble at around 60Km(40 MPH) than it quits after that speed.Still under warranty....the dealer told me tires..I replaced them,they replaced front bearings.......and a new Rear end....this week going for drive shaft.
Strange thing is they took truck out for a test run with out the rear shaft on and it was still vibrating? ? ? any thoughts or previous problems the dealer might be over looking?
Thanks in advance

 

Did they have the tires "Road Force Balanced"? You can get a vibration at only certain speeds because it wasn't balanced correctly. It sounds more like they're just throwing parts at the car.

 

Whoa, I just read your message and just about passed out. I went through hell for over 6 months while they kept changing the tires and wheels (road force testing them), putting drivelines on the truck (3 to be exact), and basically not able to figure it out. My truck was a brand new 05 LE. I ended up trading it off cause no one seemed to beable to fix it...or they didn't really care.
Since then a guy told me it could have been harmonics in the engine that caused the vib. If I were you I'd get rid of it. It may save you piece of mind and years on your life.[]

 

I had a similar problem on my 05 Nismo, it turned out to be the U-joints. The service manager had never changed a u joint in a nissan before and ruled it out for many hours of trouble shooting. My symptoms were started about 45 mph and went away around 60

 

what kind of vehicle is this it sound like a 4wd vehicle, well if they still had a vibration with the rear drive shaft out it narrows it down to your front axles and front drive shaft. to me it sounds like there just guessing on the repairs by throwing parts at it. let us know if any progress
