Suspension/Alignment (?) Troubleshooting Question
Any advice is greatly appreciated! I have a 2015 X5 xDrive35i with M Sport Package (337) and Adaptiv M Suspension (2VF), with 56,xxx miles. I purchased this car one year ago with 42,xxx miles.
Often times when driving over the lousy bumpy roads here in Dallas, TX, the car seems to shimmy from side to side horizontally, especially (only?) at the rear. The sensation stands out because I expect up/down movement throughout the entire car, not the side to side movement. It is almost as if the rear of the car is being pushed side to side while the front stays planted. Does this sound like a suspension issue, or maybe a wheel alignment problem? I am woefully ignorant on these matters. I will be taking this car in for a check before a long upcoming road trip, I would like to be able to point the mechanic to the potential causes of this issue, rather than merely trusting them 100%. Hope this makes sense, thanks for any tips or help! |

Thanks for the responses. It isn't tramlining, which I am familiar with, since it is a temporary phenomenon (1-2 seconds) when driving over bumps. It is hard to describe.
Thanks again! Last edited by Cabrio330; 07-16-2018 at 08:11 PM.. |

Do you have run flats installed, or regular tires? I never had it checked, but my theory is that since the suspension compliance is designed for run flats, with regular tires, the sidewalls flexing laterally under rebound is what we're feeling. That's a pure guess, though. |

I have replaced the tires with non-runflats, so your theory could be correct. Soon I'll take the car to the dealer or indy for diagnosis. I'm naturally skeptical that they truly know how to assess these issues so keeep the ideas and theories coming! |
