OK! I was told its flat spots on the tires. Especially when the car sits overnight. Does your vibration go away at all?

Mine is definitely not flat spots. That issue will solve itself once the tires are warm. Mine doesn't go away.

To all - I appreciate all of the advice. I'm working with my tech to schedule time to get him to go through the checklist I've created from this thread. He works at the dealership, but he does work for me off the clock. I may have wait a few weeks to get a block of his time.


I will absolutely post the outcome. Thanks again.

Could be a wheel bearing? or the Bushings are severely torn? Warped rotors? possible drive shaft? Could be swaybar endlinks,upper strut mount( has rubber), coil spring isolater (rubber mat spring sits on)

i had same problem in the past 3 months... i switched wheels 3 times as well,i recently change my shocks
to koni yellows and boom! problem solved, no more vibrations even on high speeds

good luck to everybody and hopefully you guys be able to sort the shaking problems

Hi i was reading this with intrest and i was thinking shocks. as the last guy said he fitted new koni shocks problem solved. btw you can fit new oe or after market shocks you dont have to mod your car to fix it.

Ogg

any update?

Hey guys - finally getting around to posting an update on this. My tech does work for me off-the-clock, so I had to wait until he had a weekend he could spend with the car. Here is the list I gave to hime to check:

o thrust rod bushing
o harmonic dampers
o tension strut
o wishbones
o guibo coupling
o carrier bearing
o CV joints on rear prop shafts
o control arm bushings
o wheel bearings
o warped rotors?
o swaybar endlinks
o upper strut mount
o coil spring isolator
o shocks


I asked him to start with a roadforce balance, and then begin checking the list. After the balance, he said the vibration was still clearly there. He could actually see the passenger seat and headrest vibrating slightly. He then did a visual inspection under the car on the rack, retorqued bolts and "shook down" everything. Still nothing. Only find was that one of the rear rims had a slight divot.

Next steps are to get the wheel guy to repair the divot and have the shop foreman test drive it.

If that doesn't solve it, I will have to take it in under my CPO and have them go to the next level - meaning pulling off parts, replacing things and likely checking the drivetrain.

I'd hate to think this is all because of a slight divot in my rim, but I'm sure that would be preferable to the CPO battle I'd be into next. Although I know that is better than no CPO at all. CPO expires in February.

Thanks again for all of the help. I'll give you guys an update next week.

i have the same exact problem. it occures at 75 mph. It seems like e60s all have the same problems.

The e39's had major problems with vibration, I really think it's wheel balancing but if you press the breaks and the vibration becomes more apparent, then it's bushing/control arms.
Mine also vibrates but I know it's the tires. Need to get them balanced.

ask your mechanic to check for "cupping" in your tires. Its a long shot but it may be the cause of your vibrations. It was "cupping" that caused my vibrations at 70mph-86mph.
