Shaking vehicle

sedona

#1

I own a 2005 Kia sedona lx with roughly 105k miles on it. the van has been shaking at around 60mph and up. i went and got an alignment, a hub bearing, and the two front tires replaced, but the shaking is still there. it only appears when accelerating, and if i let off the gas and coast, it pretty much goes away. any ideas?


#2

motor mounts?

High speed specific vibration usually means worn tires or worn struts, tires out of balance, low tire pressure on one wheel, or of course front-end problems. If you’ve had the car aligned recently, the front-end should have checked out okay. I’d have the rear tires and (front-end) struts looked at. It might also be a motor mount as suggested, but I think you’d likely feel a vibration while stopped in drive as well. Not always. Something else to look at though.

If its acceleration only & goes away when coasting then I’d suspect one of the inner CV joints.

Another vote for a worn or binding CV shaft. Unfortunately the shop may have to remove it (them) to inspect.
