Hi

If the problem isn't fixed with the balance, have the front control arms to replaced or replace only replace bonded rubber bush if are possible !

Thanks for replay!
i replace complete set of front arms.i use meyle hd set. it is beter but not ok.
if i use OEM rims 16" with winter tires is ok. but with no OEM 17" rims and summer tires the vibration on seats is still present.
i have filing that vibration come from back suspension.because steering wheel don`t shake.
have any one have other experience?

Hello, again,
i resolve problem . i replace rubber bush on front axle, lower, rear r+l side.and shake almost gone.
now i order also both rear control arms because i can`t buy rubber bushes. meyle parts are not so good as they say.if someone have similar problem should buy lenförder parts or OEM parts they are much beater quality.
