Can you guys help me troubleshoot a vibration issue on my '07 G35x?
So i have a vibration in the wheel and seats in my 07 G35 x. (This post may be long..so bear with me)
Was there a little when i bought the car..but noticed the tires were very very choppy. So i got new tires. It was fine for about 2 days..then all of a sudden it was bad again.
Now this vibration isn't always vibrating. It comes and goes. 10 second vibration..slowly goes away..then fine for 10 seconds..then i can feel it come back through seat to wheel again..over and over. Happens at about 65+ mph.
Then about 8 months ago my engine blew. Thought that was it..but nope. So i bough new wheels and new tires (again)..made it worse. Ended up selling those.
Also had about 6 tire balances within 3 months.
Here we are today..still does it. Some days are better than others. I had 4 mechanics look at it and all said my car is fine. Infiniti said it's the tires..yet i have tried 3 different sets..but they still blame the tires (they are morons BTW)
Also i throw the car in N when it's doing it on the highway and it still does it so i don't think it's trans. It's a mess. Some days are not bad..some horrible. But always comes and goes..10 seconds on..10 off...
Anyone have any guesses? lol

Its your wheel bearings up front, known issues. On some G35's they prematurely fail.
You should check out g35driver.com for more info and do a search on wheel bearing, tons of info.
Hopefully you still have some warranty left of got the extended elite care coverage, otherwise you will have to pay out of pocket

I'm not saying it's 100% your bearings, could be something else, but I'd bet a six pack it probably is

Though it's hard to diagnose it, any loose suspension components can cause vibrations at speed. My RL went through a similar stage...where constant vibrations at certain speeds would occur. I went through 2 sets of tires, balanced them so many times the shop began to hate me (I bought lifetime tire balance), 2 sets of wheels....did a ton of alignments (also had lifetime alignment) yet vibration was still there! Finally, I noticed that the front lower ball joints were leaking so I changed them along with inner, outer tie rods, sway bar end links, upper control arm ball joints and bolts, front sway bar bushings, top front strut mounts, drain and fill tranny fluid and differential fluid, re-balanced the tires and did another alignment and viola.....no more vibrations!
So I really don't know exactly what I changed that stop the vibration but doing all that resolved it. Could be worth a shot on your part!

Also..at about 95-100 MPH..it goes pretty smooth again...so it's really from 70-85 ish. Downhill it seems worse..anyone else have any suggestions?

So i have been actively looking for a car with many dealer trips to find nothing...frustrating when you have been looking for 3 months and not found a thing you can decided on...sucks being picky..guess i will take a break for a month or so
I want to dump this car for this vibration along. main reason

Just curious... did you check the rating load of the tires to see if they’re right for your car? I know that some tires will form a flat spot while the car is parked and once you start driving the car will vibrate until the tires re-shape.

Also, before my TSX I had a Nissan Frontier rear wheel drive and I had to replace the drive shaft bearing because it was vibrating at certain speed just like you’re describing above. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
<o:p></o:p>
Lift the car and with your hand try to move the drive shaft from side to side, if it gives replace the bearing as that should’ve a tight fit. <o:p></o:p>

Does the car feels like you're crossing rubber strips on the road? And, does it when the RPMs are steady and you slightly give more gas? Does it feel like the transmission cannot find the right gear to be for a few seconds? <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

Doesn't matter what RPMs are..more dependent on speed. if i slip it into N it still does it. So i kinda ruled out trans.
Found something the other day. My lower control arm bushings have cracks in them. Both sides. Now i don't know if it has always been like this. I don't think it has and is leading me to believe that the constant vibration over a year has worn the bushings out since all mechanics 6 months ago said bushings were fine. What's your take? Will a constant vib ruin control arm bushings? Or have i had cracked bushings for almost 1 1/2 years now with 4 mechanics overlooking it?
It seems like diff tires and wheels still cause it to do it..so something has to be wrong..just have no clue what.nor does any mechanic know

Don't think you mentioned if you have taken it to the Infiniti Dealer yet or not, if not I think it may be time. Let them diagnose it and fix it elsewhere for cheaper. It will be a bit pricey but at least you will finally be able to resolve.
Still think its the bearings

Obviously it seems like you've covered the basics like balancing and alignment. I for one can attest to the lack of skill that most mechanics have when balancing a tire. But being that you said you've had it done 6 times I'd have to assume its right.
As for suspension parts, those problems would get compounded with speed like you're saying once you hit 65mph. But the difference is, like with unbalanced tires, they find a sweet spot faster you go. But with suspension parts, it shouldn't feel better at 90 like you're saying.
Its odd you're not hearing any sounds because I'd say whoever mentioned wheel bearings and differential may be onto something.
Sorry man, all the issues have been covered.
If its rear tires, you usually feel it in the seat more, if it's the front tires, you feel it in the steering wheel, if its drivetrain vibration you feel it in the pedal.
Good luck borat.

Just sucks becasue it's only a high speed vibration..which usually means wheels..but it's not. Oh and something else i should add...when it's vibrating and say there is a bend in the highway and you turn left or right..it goes away with turning the wheel almost 75% better and then when you put wheel back strait..it vibrates again. I know the suspension is slack when it's strait and tightens up when turning..so not sure what that means

So i rotated the tires this past weekend and now the vibrations are worse. I never rotated the tires becasue the ones up front balanced the best and were the smoothest..but now they are pretty choppy..heel to toe wear..so i moved them to back and the vibs are worse..as expected..but they still go away when i turn the wheel left or right on highway..so fucking strange...want to keep it..but driving me insane every time i am on highway
#28
I had aftermarket wheels 8 months ago..bought the wheels to try and fix issues..only made it worse..so it's not wheel. Tonight the seat vibration was HORRIBLE. Vibs are much worse now that i rotated tires. You would think it if were an issue with the car..it would stay the same regardless of what tires are where.
Tonight really made me dread driving my car. I now avoid driving on highway which is tough when possible since i can't go above 65 without being shaken the entire time. I was looking at new cars..but dealerships are pure evil and i needed a break..but now..i may start looking again after how bad it was tonight. it's so werid. Some days are better..some are horrible..like tonight..and tomorrow..it may be better
Thinking about putting the tires back where they were before..but such uneven wear becasue i haven't rotated them in like 8K miles due to having less vibs when certain tires are up front

my vote is damaged wheels. If the problem goes when your turning that means that the problem is being masked by the extra stress exerted on your suspension. Thus the problem has to be with a part flexing when it shouldn't (IE loose lug nuts or improper lug nuts) or a part such as a ball joint or bushing that is failing.

It's not the wheels
