I have a 2009 Camry XLE that I just replaced the struts of, and I got it aligned, rotated, and balanced. Ride quality is like a brand new car, and the vibrations I would get when accelerating at 2000RPM at any speed is now gone. However, as you can tell by the title, it vibrates now at a very specific speed range and when I'm accelerating/pressing the gas.

It gets the worst around 45mph, and it feels like the car is shaking from side to side, if that makes any sense. It also tends to happen between the high 1000s - 2300 RPM range, and as soon as I drive outside of the aforementioned speed range, the vibration is no more. Now, I'm not sure what exactly it could be. I've never been to this car shop before but it's highly rated, so what if they just didn't balance perfectly? Is there a way I could rule the tires out somehow? I'm pretty sure the gas has to be pressed for the vibrations to occur in the RPM and speed range I mentioned, but I will test this out very soon and I'll report back. Anyone have any ideas?

UPDATE: Just got back from a drive and confirmed a couple of things: 1. the vibration only happens when I'm accelerating, and 2. this happens in all gears 3 and up, from what I could figure out given the Camry's fake "sport" mode.

 

Any relationship to MPH and this vibration?

Could be a failing drive axle. Try making 360 turns in both directions at slow speed and listen for grinding/popping noises.

 

Yeah, it vibrates between 40-50mph, only between 1500-2400RPM. If I go pretty hard on the acceleration (much higher RPMs, past 3300), the vibrations continue to around 55 or 56mph and then it's smooth again. I'll do the 360 check but I don't believe my axles grind/pop.

 

Update, did several donuts at slow speeds in both directions, no grinding/popping/unusual noises heard :/
Have anything else I could try out?

 

A shutter?

A shutter under acceleration can be caused by bad inner CV joints. Check inner joints for excess radial play, turn boot, etc.

 

I'm having the exact same problem. Did you find a solution or cause?

 

I have an 09 that has horrible vibration, spent thousands replacing parts based on false promises from mechanics, bearings, shocks, finally gave up and just parked it. It was cheaper to just buy another car so I bought a 2003 SE for 2 grand a year ago and I just drive that all over instead. It would be nice to figure it out one day but the quality of service is getting pretty bad these days. This morning I used the full size spare from the 03 and replaced each wheel ruling out a wildly unbalanced tire. Once you get past 35 mph the thing just starts roaring like a freight train, never felt anything like it. The faster you go the worse it gets. I don't really like driving it, the noise is deafening. Car drives straight as an arrow, no steering wheel vibration of any kind, everything feels great otherwise.

Soon everyone will just get an EV so they have 20 parts vs. 2000 parts to deal with regarding drive train. When spring rolls around I'll swap the 03 tire/rims onto the 09 and see what that does. The tires on the 09 are EL700 Advantas. Who knows, now that it's driving me nuts maybe I'll do it next week after work when we get a heat wave.

The axles would have to be pretty bad to start vibrating at 35 mph, the 03 has an axle that's worn and that doesn't even start vibrating until I get it up to 80 mph and that's hardly noticeable.
