2004 Mercedes S430 vibration at 60mph and over
I am new to this forum and very excited to be here, I am a Mercedes lover and I think its the best car around. I have owned many Mercedes in the past, I am stumped at the current problem I am having. I have a 2004 Mercedes S430 with 89k miles alabaster white with AMG package and 18' original AMG wheels. I noticed a vibration at 60mph and over after i release the gas not when accelerating. I have changed lower control arm, bushing, sway bar link, transmission mount, cheked engine mount and mercedes specialist said they are in good shape, had the tires road force balance, the vibration still there, the mechanic sugested to have the tires balance at high speed with wheels on the car. While doing the high speed balance on the front wheels (the rear could't do it becouse the car has independent traction and the specialist was affraid to do it but did it on the machine) the car was vibrating till the point you could see, after adding the weights there was no visual vibration anymore. I got in the car and start driving on the freeway and same vibration is there, the front passanger seat is vibrating as well. I stoped at my mechanic to explain him that high speed balance didn't do it and what is next? Checked the tires they are in good shape, ball joints good shape, bushings good shape. Now my mechanic tells me that the drive shaft could be out of balance and there is no way to check that than to take it out and send it to do a balance on it. The place he whats to send it is Wenco wich is located in Van Nuys California. Does anybody know about this place?
I'm also afraid that maybe the drve shaft is ok and if we take it down we won't be able to put it in the same place as original.
Please, any info would be appreciated.
P.S. in the past I had a 2002 S430 with same problem and could never fix and a 2000 CL500 with same issue never fix
