This has been happening for the past 6 months or so. I recently had new ball joints, 4 wheel alignment, and 4 wheel balance. Even with this I’m noticing a very slight high frequency vibration at highway speeds. I noticed on one of the front wheels that a weight fell off, so this might explain the high speed vibration.
However - When I’m starting at 0mph, and accelerate to say 50mph for example, the car vibrates rather substantially as the speedometer moves from around 25mph to just past 30mph. After those speeds it goes away.
I’ve also noticed that it tends to be worse if I’m going up hill, which, according to the laws of physics, would tell me that going uphill would put more pressure on the front end, given it’s heavier with the engine there. If I’m going downhill it vibrates much less.
When I drive I tend to not accelerate quickly, meaning, I don’t ‘punch’ it, and accelerate gradually instead. If I’m driving on a level, well-paved road, and accelerate quicker than regular, the vibration seems to not be as heavy.
Can anyone recommend fixes and any other tests for this? Struts, control arm, steering knuckle, drive shaft ?
