Has anyone successfully solved the 70 mph vibration from the rear of the e-60? I have an 04 545 with a 6 speed manual trans. Its had this vibration for quite some time and I can't seem to track it down. I have replaced 4 tires, 4 rims, center bearing, guibo, back rotors. The wheels/tires have been balance multiple times, but it never changes. I have tried using metal and plastic hub rings with no changes either. The vibration comes and goes around 70 mph. Below that its smooth as glass and around 75-80 mph it goes away. Anyone?

 

have you checked the Guiding suspension link w rubber mount and the Wishbone rubbers. 14 and 19
it is very commen for these to brake. most of the time they brake at about 50000km to 60000km, if driving on smooth road it will be abit longer.

 

I have checked those guide links and they appear to be good. They are tight and not broken. The rear end seems to be tight all around. No play in any of the components that I can tell. Any other suggestions?

 

i had the same problem , need to check your tires with roadforce machine , if the tires were bent (inside damage not visible to our eye) got to change them. mine were balanced 3 times in3 different places.only the last guy did figure out what the problem is.
may be same problem.i had vibration on 65 all the time , 60 or 70 was fine.
