Car shakes when I get on the gas...

[wakebums]

Ok, I put new tires on the car, and I've had them re-balanced a couple of times, and My car still shakes when I push on the gas. It only does it when I give it gas. But when I take my foot off the gas it stops!!!! I know its not the tires now, What is it???? And If I have more people in the car it makes it almost go away.. Someone please help.. Is it a driveline weight? Motor mount? Has this happend to anyone else?

Thanks....

Sounds like either a transmision, driveshaft or angle gear issue or...
it could be as simple as a bad motor mount, either upper or most likely a LOWER MOUNT

i have a 2003 xc doing the same thing, its not the tires, replace all mounts, still have the shake, going around 50-65 mph, when i get on the gas it shakes pretty bad,

Check inner CV joints. Will cause shudder on take off, and acceleration during flight.

Sounds like a driveshaft. Usually it's the right shaft in my experience, but it doesn't rule out the left. Is it more pronounced if you're giving it gas turning to the right or left slightly?

It doesnt sound like the problem the guy had in that one link.. It only does it between 50 and 65 mph.. It shakes like crazy!!!!! It just seems like it keeps getting worse.. It used to be at 60mph only,, now its gone down to 50 and up to 65...

Do you think its the cv boot?
