Hey guys, I have a problem with my 08X (AWD).
It is stock except it has been lowered on eibachs and has a rear camber kit.
I want to know what you guys think...any ideas would help, anything please. Hopefully someone's experienced this or has a clue.

When I'm driving EXACTLY 60km/h (37mph), give or take a couple km/h, the car has a wobbling feel to it. Hard to explain but I'll try...The car will feel like it's wobbling, as if the front wheels are engaging then disengaging, catching and letting go, or as if the motor is wobbling, where you feel it in the seat as if your seat was repeatedly tapping forward and reverse.
If I let go of the gas, it seems to let off. Once I hold the gas pedal down and cruise at that exact speed, it gets that wobbly, catchy, vibrating feeling.

It was always there, at least majority of the time, since I bought it, but I always tended to ignore it until my girlfriend started commenting about it. I thought it was normal at first, then I figured it would go away, but when she had to point it out to me a few times now, I just have to figure this out.

I know it's not my wheels out of balance as it occured on the stock rims and my new summer rims, even after roation.

My assumptions: could be an AWD sensor telling my front to engage then disengage, possible driveshaft balancers, defective clutch-pak in the AWD transfer case, I don't know, insert your assumptions here.

I know the dealer should do this for me, but I'd like to give them some possible causes as I'm sure they'll tell me some BS like, "your tires need to be rebalanced, we can do that for you for $89.99"

So, any ideas???
Thanks Guys!!!!

 

What wheels do you have? are they staggered? I'm guessing no cause you rotated it but if they are staggered it might mess up your awd sensors.

 

^^^That was also my question, have you always been running wheels and tires that are of the same size on the front and the back ?

 

When I bought it, the car came with stock 17's, same size all around, which I'm currently using as my winter setup. My 19's are also the same size all around and they match the 17's diameter (245-40-19). I am NOT running staggered.

My wheels are definitely not the issue here, but I like how you guys are thinking.

You guys both have X's, do you notice the vibrating/wobbling at 60km/h.

 

Hey! I recommended to put back your 17" stock and see if this ploblem still occur...I'm thinking is yur 19" .Anyway try!!!
I use to have 19" from G37 all the same diameter.I feels the same vibration when 60 and above.It's like the wheel going the different way.So i switch back.I'm running 18" Stock now.and No ploblem.

 

I tried that for you today was going 37 mph nothing was wrong. Does it happen if you go faster than that?

 

No , I do not have any wobble or vibration at any speed, with my 17s or 18s.

This might be a silly thought but I wonder if the drop can affect the awd system at all. I just say this because when you raise a 4x4 it changes your pinion angles on your differentials, so perhaps could this affect the front diff.

 

I definitely feels something wrong with the 19" fitment with our GX.It does effect to our AWD system.

 

i have an 07 x on 19 m45's and havent noticed and wobbling problems. im not dropped though, that could have messed up something with the sensors....you never know.

 

I don't think you have a smooth ride as 17 or 18 set up.I have try all of them.
the 19" was worst.I still have 17 and 18 stock today love them both.

 

If everything is running true, no imbalance, and they are roughly the same OD as original, then they should be okay.

I do agree with you that the ride gets rougher as you increase the wheel diameter because of less tire shoulder height. That's why I am only running 18's even though 19s or 20s do look nicer.

 

+1^^


of coarse i dont, but the 17's look horrible.

 

that's why i running 18" and still keep 17". Let get back and help this guy.
We are not trying to hi jack this thread. LOL

 

To clarify, I am on my stock rims, still doing it, and yes Gee35X, my 19's are the exact same OD and for that matter ID.

And yes WannaBmyG, they don't look all that great! (not sure about horrible )

Thanks Csquared and Gee35X, good to know it's just me then.

It only happens at that exact speed, not any slower or faster. Once i speed up or slow down from that 60kmh / 37mph it goes away

You guys seriously think the drop may be affecting this is some way?

Again thanks everyone, i appreciate it

 

well made an apointment w/the dealer. i'll let you guys know where this goes
