ffe Report post Posted September 6 I sometimes hear a very loud vibration while accelerating. I'd say it never happens under 40mph. It disappears when letting off the accelerator. And I think flooring the accelerator seems to also end the vibration. If I had to guess there's a certain range of toroidal tension in the rubber of the tires that changes the resonant frequency. When they're applying a certain "g load" they are subject to vibration. If you maintain your speed the vibration stops. I suppose a bearing could also cause it. Is there a good tool or method to identify with certain the source of such a vibration? If nothing else I'd like to prove what corner its coming from consistently, and then prove it again after the next tire rotation. When it happens it's so loud. and I'm never sitting in the center of the car. So it's hard for me to know where its coming from. but it happens when no other cars are nearby, and it I'm very sure it's not the rumble strips on the road. pavement doesn't look particularly bad. it's so hard to predict where it happens I don't think its any single area of pavement can reliably reproduce it. It makes me cringe each time though. Quote Share this post Link to post Share on other sites
Sky14FFH Report post Posted September 25 Many of us have been struggling to identify the vibration coming from the glovebox/right passenger door area. It's not a loud vibration though, just a mild one that happens around 2200rpms for me. It's an annoyance related to the interior trim or something. The frequency of it happening reduced somewhat when I switched to Mobil 1 oil but it still happens. Some have discovered it was coming from within the speaker area. I haven't bothered to mess around with it as it doesn't bother me that much. There are a couple threads on it but I don't think that is what you are referring to?

ffe Report post Posted September 25 What I'm hearing is almost certainly coming from wheels or tires. I'd bet Tires. I wish there was some instrumentation to monitor vibration levels on the wheels Or maybe just vivbrations detected at each cormer of the car, which could hint at the cause by which was higher/lower. Super neat if it would record the velocity in real time, throttle position, along with the vibration dfata, so you could tell if it rose/fell with rpms or with speed over ground Quote Share this post Link to post Share on other sites
Sky14FFH Report post Posted September 26 Yeah I'd get that hub checked. For now jack up the corner it is coming from and check the movement of the wheel with your hands, first right and left then top and bottom. Then check underneath see if there is any play in the ball joint. Quote Share this post Link to post Share on other sites
