Vibration

[deseans123]

Need some help with something...if anyone has had this problem or are familiar with it. Ok, so i have a an '04 fx45 w/ 20" factory wheels. When i'm driving b/w 50-60 i get this pulsing vibration i can feel in the pedal and it's accompanied by a humming noise. I figured it may just be the tires or allignment, but i'm not sure at all. Any help/feedback will be greatly appreciated. Thanks:squigglemouth:

Factory tires? Any other wheel/suspension mods...spacers? Any steering wheel vibration? also any vibration to the pedal while braking?

Everything is factory on it...i just bought it about a month ago. I talked to service guy at carmax where i bought it (he also drives an fx45) and he told me it was due to the feathering of the tires. I'm familiar with feathering as i also have a cobra with a staggered setup, but the pulsing is too intense in my opinion to be feathering. It also gets worse when i make a turn at those speeds?????????it's aggravating.

I would take it to the dealer to have it checked out. What year is the FX?

 

[deseans123]

It's an '04. You're saying i should take it directly to infiniti? It's till under warranty so that's probably a great idea.

 

[deseans123]

Oh and to answer you last question fxlr8, there is no vibration during braking, hard or otherwise.

 

[Dr.2K]

It's an '04. You're saying i should take it directly to infiniti? It's till under warranty so that's probably a great idea.

Yes. Good luck with this issue and let us know how it turns out.

Warped rotors, 99%

 

[HKN_87]

Do I have to change all rotors ?? how much is it gonna cost and what rotors should u guys suggest? oem or aftermarket rotors?

 

[gto]

How many times have you had them rotors turned?
Also, how old are those Toyos?

 

[HKN_87]

hmm i just changed my pads ones. i dont know if they turned my rotors.
Toyos are almost two months old.

 

[Psiclne]

oem or aftermarket rotors?

I would never go with OEM rotors ever again. Noisey things.

 

[gto]

Hmmmm . . You shouldnt be vibrating. Did you curb anything to throw the alignment?

 

[MTN FX]

I got the wheel vibration at between 50 and 60mph as well but only after I had my new 22's w/+15 offset and hankook 265/40/22 RH06's mounted.I'm thinking it's an alignment issue.After running it this way for a few weeks the vibration has become less.
My question is do you think that having a wider wheel offset with +15 would change things enough to require an alighnment.The tire heght is as close to the oem's as I could keep it in a 22".

 

[HKN_87]

i dont know. i think im gonna check everything this week. Thanx for help guys. i appreciated.

 

[gto]

it could be off balanced wheels too. I'd start at the place you had those mounted

 

[HKN_87]

i think thats the problem. first 1 month everything was normal. after it starts to vibrate. im gonna install my springs wednesday, also im gonna check my wheels too. maybe ill turn my rotors.

Find the vibration problem first before you do anything else. Keep the blame in one place . . the tires . start there
