Hello everybody,

I have a 2002 Audi A4 3.0 with CVT transmission.
It has 54,000 miles now.
Recently when I drive more than 50 MPH, my car will start shaking.
I replaced spark plugs, coils, tires and I also did balance and alignment, but this problem still occurs.
Does anybody knows what's wrong with my car?
I don't wanna go back to dealer, because it will cost me a lot of money.

Thank you

 

does is shake consentley over 50? have you checked the tires, your might want to ensure that they are properly balanced? does it seem to come from one corner of the car?

 

Yeah, does it shake during acceleration/during braking/or constantly right after you hit 50mph???
It might be your wheels- check that all the nuts are sitting tight- and plz dont wait, just check to be on a safe side.
do u have wheel spacers???

 

It shakes constantly right after my speed over 50mph.
I did borrow 4 wheels+ tires (almost brand new) from my friend and installed on my car, but the problem still occurs.

 

Make sure your wheels are mounted and balanced correctly.

 

I did balance and alignment for all 4 tires, but it doesn't help at all.

 

Are u manual or auto???
Does that happen if you going over 50mph in neutral??? If it doesnt, than it has something to do with a drivetrain.

 

if you can determine which corner of the car the shaking is coming from you might want to get the bearings checked on that corner of the car, maybe it needs to be replaced before it does some damage to your spindal.

 

My car is automatic.
It doesn't happen if I go over 50mph in neutral, it only happens when I hit the gas pedal.

 

CV Joints? Possibly Drive Train? Is it a shudder or a shake? Could be the protective boot on one of the CV Joints has gone bad?
