What susp. components to replace for steering wheel shake >80 mph?
I’ve probably gone through 4-5 wheels, none of them hunter road balanced or the sort. But what’s the most likely culprit for wheel shake over >80 mph? It takes me a good arm workout to stop the shaking and when I do that the car vibrates. Even with spacers, they are the proper hub sizing.
Whether it’s OEM EDC susp 46k miles and airlift performance 8k miles, I still experience the same symptoms. Last edited by Route 16; 11-18-2018 at 02:17 PM.. |

I’ve got a minor shake at 80-83 as well, annoys the hell out of me. I haven’t dug in replacing parts (car new to me, 48k on it) but I will soon.
Tires/balancing, alignment, and FTABs are what I’m starting with. |

Front tension arm bushings.
They’re cheap and easy to swap out, so I’m starting there. If my list above doesn’t do it, next route is wheel bearings and rotors. I’ve never had a vibration at such a narrow speed range in other cars and can’t figure it out. |

I had the same issue. Thought it was a wheel bearing. Ended up being the front tension arm bushing was toast on my drivers side. Jack up the font of your car and check to see if there is any play in those bushings. |

I got 172k and have been shake free.
Check for tire defect (out if round) Check for bent rims Wheel RF balance Change tie rods Change tension arms Change lower arms Change wheel bearings Last edited by WingZeroX5; 11-21-2018 at 11:52 PM.. |

Dealing with the 75-80 shakes on my 77k e92M3. Subscribing to this thread as I'll be working through some stuff. Balancing didn't cut it, no bent wheel, fresh alignment. Will begin picking off crap from cheapest to most expensive, will report back with my findings over the next month.

i have same issue as well, but its for sure spacers. i didnt have any issue until i started running spacers on the front. whether its the spacers themselves, or they helped to wear out something else, it only started rite when i put them on. collecting parts rite now to replace everything on the front.

A trick to help with front spacer vibration issues:
-lower the car just enough that the tire is in contact with the ground (don't go any further) -torque the bolts down to spec -lower the car fully and remove jack Basically, you want to torque them down fully before the weight of the car causes the wheel to move against the spacer. Even better when done with the car in the air (hoist or 2nd person holding the brakes).

Almost all the time, it is tires. Was the car lowered and what alignment setting.

When chasing a steering vibration, I take low hanging fruit and work my way up:
1. Are Wheels/Tires balanced with a good Road Force balancing machine. The lower tier machines are simply not as good. 2. Is a wheel bent 3. Are the rotors warped (assuming vibration is when braking or they are so bad the warped rotors are hitting the pads without brake application). More involved shit 4. FSB endlinks bad 5. ball joints going in control arms 6. tie rods 7. Every other bushing on the front not addressed by the foregoing. Most often as not, it is badly worn tire, wheel out of balance or bent, but it could be one of the rest.

I know the road force on the wheels is under 15lbs each. The biggest thing was I was in the same situation where I tried multiple Rims with the spacers and got vibrations. After I got the BBS properly balanced with under 15lbs of RoadForce, the virbation was finally gone.

my fix...it's gotta be my wheels not balanced correctly, I just switched to M359 wheels I bought from a friend, they don't shake at all, so it's gotta be balancing.

I had loose nuts on control arms after monoball bushings, would shake sometimes not always...
Jacked car up wiggled the tyre and had slop in it, drove like a new one once they were torqued up properly! (I had a heap of work done all at once the shop must have nipped them up but forgot to torque them) |
