Steering wheel vibration

Chers collègues,

J'ai remarqué des vibrations dans le volant, est-ce que c'est la même autoroute normale, je ne le remarque pas en ville?

J'ai une Coupe 2013 et je n'ai pas de problèmes comme vous le décrivez. Est-ce que votre voiture reste assise pendant de longues périodes? Des taches plates ? Les pressions inflationnistes sont-elles bonnes ? Prenez-le à votre concessionnaire si elle ne disparaît pas.

Le 80mph shake est assez célèbre sur la M3. Si c'est vraiment mauvais, faites-le vérifier. Il devrait descendre autour de 90 cependant et totalement allé plus près de 100. Mannnnny propriétaires l'expérience.

J'ai la même chose. Il arrive autour de 75 et continue à environ 85-90. J'ai remarqué qu'il ne tremble pas quand on tourne autour des courbes et sur certaines surfaces. Il semble que ce soit un "problème" commun aux propriétaires de M3.

Le mien vient de commencer cet hiver. Se passe 80-84mph. Rien sur les autres paramètres de vitesse. Heureux de savoir que ce n'est pas seulement moi. J'ai pensé que j'aurais l'équilibre et l'alignement quand je changerais de pneus cette année.

J'ai eu un tremblement dans mon volant à environ 75-MPH ainsi, mais alors j'ai obtenu mes roues avant et les pneus "Roadforce équilibré" et il est parti.

Rien ne rend cela plus évident que le volant spécial BMW avec la grande bande floue en haut!

J'ai eu de nouveaux pneus PSS avant récemment et il a surtout disparu, mais pas complètement.

Je parie que la plupart d'entre nous (malgré tous nos efforts) ont un peu de débrayage dans les roues avant en raison de l'impact avec des nids-de-poule et autres. Les 18 et 19 ans sont difficiles à garder parfaitement ronds dans le monde réel.

Je ne l'ai pas remarqué une fois que j'ai eu la voiture il y a 3 mois. Je suis à 4K mls. Je l'ai remarqué autour de 3k et a commencé à devenir plus évident après avoir garé la voiture pendant une semaine quand je suis allé sur vaca.

In many cases, the vibration comes from bad wheel balancing. I had my wheels balanced twice after I got my Michelin PSSs at a local tire shop and the vibration (75-85mph) did not got away. Found a shop that does road force balancing and they got it right. No shaky steering wheel. The owner of the shop told me the suspension and steering setup are really sensitive to imperfections.

Also try remounting your wheels. Make sure to do the star trace torque down multiple times building up the torque as you go (vs. torquing only once or twice). This ensures a flush mount between the wheel and the hub.

Thank you as usual!

Great. I took my 13 M3 with 2600 miles on the interstate on a trip to New Orleans and over 75mph for the first time this past weekend and it vibrates. DAMN.

So, since the car is new, I should focus on the lug nut tourque and road force balance of front tires. Right?

It's a good start and it is a relatively cheap process.

You need to rebalance your wheels. Also check if you have a bent wheel on the inner barrel. This was my issue when I bent a wheel. It was the rear passenger wheel inner barrel caused vibration at 90 mph.

check for weights as well... one might be missing.

OP, what brand tires do you have?

I tried everything to get rid of my vibration. Road force balanced, balanced at different shops, etc. Always had the vibration around 75mph. Though my wheels had a bend, swapped my wheels, thought I had warped rotor(s).

Solution: I got rid of my Continentals and put on Pilot Super Sports - all is fine now.

It was the dang tires. As the contis wear, they get noisy and vibrate.

Note: I had all of my wheels checked, and all of them are tru.

Usually vibration through the steering wheel that gets worst with increasing speed is just because a wheel weight fell off or the wheel(s) are improperly balanced.

Wheel weights are just flat, rectangular, lead weights tire installers stick to the inside of your rim to balance out the weight distribution of the wheel after mounting a tire. The adhesive can be pretty weak, so its common for them to fall off.

Just take the car to any tire shop and have them rebalance your wheels, check all 4 wheels first to see if there are obvious signs that wheel weights came un-stuck of just one wheel. This way you wont have to pay for them to balance all 4 wheels.

Low cost tire shops are notoriously bad with balancing, so if the vibration continues afterward have another shop re-balance all 4 before you start getting worried.

Dont let them charge you much much to balance, it literally takes 5min per wheel if your good and the balancing machine tells you exactly what to do. $20/wheel is a lot

Ok, so riddle me this - Winter wheels (4 x 18" same width) with winter tires, vibe at 80. Swap to summer wheels, staggared setup, new tires, different brand, vibe at 80.

What to look at next? Vibe is only at 75-80, about 2mm shake (stupid blue strip!).

Alignment, wheel bearings, steering linkage and bushings.

My tuppence.

In this order try these steps -

Take off the front wheels and clean the face of the hub and the inside if the wheel of all corrosion. Check for buckles / damage too. Refit and check for improvement.

Get wheels balanced if problem persists.

Get lazer allignment if problem persists.

Replace tyres.

It's V common. Best of luck.

Ken.

get rid of the tires

I have a '11 E90 that has vibration from 80-85. Took it to the track a few days ago and the vibration tails off from 90-130. Brand new Michelin PSS up front with a 4 wheel alignment
