vibration/ wobble on highway
hi all- my x5D rides great except for a noticeable wobble/ vibration at highway speeds. it is not the worst thing- but on long smooth highways it drives me nuts. the dealer rotated and aligned the tires- but it still does this. any thoughts? somebody said a thrust rod bearing?

Thrust arms on the front suspension (rod bearings would be an engine thing). Depends on your mileage, but others have known them to go as early as 20-40k miles, though they should go 80-100k miles for most. Tie-rods (steering) ball joints can also go and lead to what your describing, but that's usually secondary to the thrust arm bushings going bad first.

Have someone look at your engine while you hold down the brake and slowly accelerate. If your engine moves up, then it is your engine mounts.
Check your tires. It might not be noticiable, but you might have bumps or uneven wear. The easiest way to check them is to remove the tire and roll it while slightly holding your hands to the thread… you will immediately feel if there are uneven spots. The tire has to be rolling to check this properly. Make sure your lug nuts are tight. |

I seriously doubt it's motor mounts unless your north of 150K miles. My first step would be to have the wheels/tires road force balanced to rule that out. If that checks out I'd look into the transfer case recalibration if it's an xdrive. Plenty of cases were the transfer case will self retard itself with worn tires or improper tire/wheels setups. Tons of reports on here having shuddering or vibration at highway speeds in which transfer case fluid is changed and recalibration performed (w/ ISTA) and all vibration is gone.

If it was a wheel/tire balance issue then the vibration should still be present during coasting. Transfer case vibration seems to be a bit more finicky. From asking around it happens at both low and high speeds. There's a fuse you can pull that disables the transfer case. If you pull the fuse and the vibration goes away you know the transfer case is the issue.

This is for if the other posted solutions do not work.
If you have a jack I suggest shaking your wheels (like how one would test for bad wheel bearings) to see if there is any play. If you also hear a pulsating humming noise at highway speed (mine was at 55-60+, more noticeable around 70), then look into your control arms. I replaced both front-and-back front control arms (do both sides--so 4 arms in total) on mine and it drives fine again now. Good luck! |

I have the same issue and guessing it’s the Conti DWS tires. Have 12k miles on them.
It’s not balancing. 42k total miles on the car. |

May be, may be not. What have you checked so far? Did you check anything at all? Tire pressure? Tire balance? Visual inspection? Suspension? Engine mounts? Tranny mounts? It can be anything, if you really want to solve the issue you need to troubleshoot it a bit more.

RF tire is out of round. I’m having it replaced then both front road force balanced. Bought them at 28k miles and now 45k. |

Figure I'd give a quick update on my issue too. Had my motor mounts changed and now my vehicle is serene 🙌🏽 (I got them done for free from my INDY because of some issues with them, so they did not charge me)
The passenger side mount was busted. I'm guessing it's because it sits directly under the DPF, and it gets cooked. The bottom looks like it was rusted (looks bad). The driver one didn't look bad, just dirty. I'm sitting at 106k+\ |
