      Vibration on acceleration

      Let's say I'm cruising at 75mph and I press the accelerator to in increase speed and I get a vibration. When I back off the throttle it goes away.

      I'm running Michelin super sports only a few months old. Any feedback?

      Thanks guys

      Is the vibration in the steering wheel? If so, it's likely wheel balance. Try putting the front wheels in the rear and rear in front. If it helps, get the wheel balance rechecked. If the vibration is from the engine, it could be the engine mounts.

      Yeah, the vibration is not in the steering wheel. It may be to some minuscule degree but the real deal is feeling it through the body as one might expect. It's definitely up front, wheels rotated last week in rear-to-front / front-to-rear manor. No change. This leads to mechanical as stated above.

      Does it also shake/vibrate, maybe even a little, while sitting at a stop light? It may be more noticeable at first start up, especially with the rear defroster on, or A/C running. If you have this also, it is probably your engine mounts. I am about to replace mine as well. Like you, I've got a slight vibration at higher speeds which will go away when letting off the gas.

      I'm going to say motor mounts on this one...if they're bad you should notice a huge difference in vibration between a gear and neutral as well as the vibration at speed. Could also be an axel I guess but less likely.

      Yes, she does vibrate a bit at idle at a stop light. Along with some extra front end noise I'm inclined to think mounts as well.

      I'm not sure if there is a visual indication or a shake test of some sort or not. Personally, I'm just going to replace all 3 of them so I don't have to worry about another one going bad later on. In my case at least, I feel they are probably all going out in one way or another. The car shakes way more than it should is what leads me to believe that.

      Another member said the bottom mount is kinda a pain when putting the new one in, so not looking forward to that one. The left and right mounts don't sound like they'll be too hard, just need to support the engine with a floorjack when changing those out.

      Most places I looked at for a "how to" highly recommended NOT putting any lifting device directly against the engine. Do some investigating before you do it.
