Strong intermittent vibration on the front/back
Hi guys
I have started experiencing vibrations when driving. It generally happens at hwy speed but also at lower speed. It feels like a flat tire almost or bad snow tires, but stronger. When I press the brake the vibration is more pronounced, the car is shaking. It feels bit rough on the wheel, and seems like it is more on the front passenger side. It stays on even if I am not accelerating. I had few guys in the back on time and they thought the vibration also moved to the back. It happens for 5 min or so then goes away. Then happens again in 20 min or so. Sometimes it’s not there for a while 1hr or so. 320 with 120k. I did the easy things balancing and fixed the bent wheel but this seems bigger and worse tix than that. I was hoping to keep the car for a while. Any insights would be great! |

Do you have run-flats or regular tires?

Is your car xDrive or rwd? Maybe a transfer case/differential issue? |

A transfer case failure that isn't warrantied will run you a few thousand, so hopefully it isn't that. I would go to BMW and have them diagnose. See what they say for $165 and turn down the labor. Take car to indy for cheaper repair. |

The vibration comes every 15 minutes. It now starts to feel that is below the center of the car. The whole car is shaking. It’s not a small vibration. I feel the vibration on the brake pedal even if not braking. It happens when going down hill without pressing on the gas, etc. My guess is the drive shaft, guibo??? |

Since you mentioned a previously fixed bent rim, that raises suspicions but at 120k miles, I would also take a look at your motor mounts. |

Can I think that this is not the transfer case? It seems like there is usually hesitation for acceleration? I don't feel any hesitation, just strong vibration shaking. Taking it to my indy again tomorrow. He was not able to diagnose it the first time, and wanted it to get worse before he takes a second look. |

I just came back from my indy
He says there were no codes which seems like it is not the transfer case. I mentioned engine mounts, he says if those go, it will shake/vibrate all the time. He said I have the upgraded guibo and it looks good Now we are suspecting axle??? So tomorrow I will be driving around until the shaking vibration starts and maybe he can feel it??? |

So eventually I figured out it was a stuck rear caliper. The heat from that wheel was much higher than any other and then the pad was worn much more than the others.
So new caliper, rotors, pads $1150. Glad it was not the transfer case. |
