Gas pedal vibration ?

[norcalpb]

Next I would try jacking up the car and try shaking the wheels (Still mounted) back and forth via its spokes. If it moves, the wheel bearing is bad.

have you tried rotating the tires front-to-back?

1 year on a bad alignment could be cupping/scaling the rubber.

I had a slight vibration coming from the gas pedal some years ago. Definitely not something you could feel through your foot, but it was very much audible.

You can try putting some sort of gasket between the throttle pedal assembly and its support to help reduce it (I used a bit of an old air filter), but it won't do a lot.

What improved the problem the most for me was switching back to 17" wheels with milder tyres.

Overall, the best advice as for rattles in this car is to live with them. It's a cheaper Toyota, not an Audi. It will probably outlast the Audi, but will do so rattling all along the way!

I would like to add that if you do have that movement, the bearing has gone really bad. In my case, it didn't have such play.

Also, I forgot to say using spacers also deteriorate bearings faster. It could have affected my ride since I used the 20mm and 25mm spacer combo for a while.

BTW, what is your car's mileage? And also, have you checked your specific tire model reviews on tire rack . Com (or some other site). Although you don't seem to have many miles on your current tires, some are loud depending on their design (like the BFG Sport Comp A/S I rode for a while), some are fine at first and then get noisier after a while.

Did you see anything (slight bobbing) on tired wheels while they were getting balanced, sped up on machine?

I have to side with that statement. Milder tires might have an effect... I'm waiting to have my vehicle returned to me in order to install the new Michelin A/S 3+ I bought. These are 87 load rating like the OEM Primacy tires, so I'm anxious to see if they are more compliant than the 91 or 94 load rating tires I've used in the past.

Also, if wheels are 18" you could feel some of the effects of the stiffer sidewalls, provided you adjusted the correct aspect ratio for OEM ride height.
