I've done searches about this, im getting a steering wheel viabration around 120km/h, also when hard braking and hard accelerating, im 100% sure it has to do with wheel balancing

my question is, would the rear wheels being out of balance cause the steering wheel to viabrate? or does only the front wheels being out of balance cause the steering wheel to viabrate?

i got two of my winter tires replaced in the front a couple weeks ago and now im getting viabrations in the steering wheel, i brought it back to the place and they re-balanced them. The viabrations were reduced but are still there, i am about to back again but im not sure what they can do after two tries.......so i was thinking, could it be the rears? they are winters aswell and were purchased and mounted at the start of the last winter, im not sure how often tires need to be re-balanced........but i dont see how rear tires can make the steerting wheel viabrate? is that possible? from what i hear rears would cause the seat/floor to viabrate......i dont really feel this i dont think....

so A) its either they dont know how to balance the fronts that i just got or their machine sucks or
B) there is something wrong with the tires, as i doubt my 6 month old steel wheels are bent..

ideas? i basically want to be clear that the rears are not causing this before raising hell about the viabrations

THanks!

It may be your alignment, or just a bad tire. When i used to work at Goodyear, we had the same problems with people coming in complaining about vibrations. Even though we balanced their wheels like 5 times in a month...

off-balance tires are noticed mainly at certain increments of speed vibrations (i.e. 45 mph to 53 mph then smooth then again at 67 to 72 mph)

alignment problems are noticebable through the steering wheel mainly by tracking (left or right or constant vehicle pulling)

bad tires (i.e. bubbled sidewall, broken belt, peeled tread etc.) are constant sounds throughout all speeds and motion

suspension problems are the same as bad tires they can also go unnoticed like an alignment problem until the tire starts to show the wear...


underinflated (looks flat, looking from distance, you see bulges on sides of tires at contact patch) or overinflated (looks overly round especially in middle of tread)tires will give you an either 'hard ride" feeling or kind of loping sound...usually results in broken belt or sidewall bubble...

look for any of these signs.....

turque you lugnuts see if that works if you have aluminum rims turque it too 100lbs and if it's steel it's 115 lbs

yeah lets try no on that...80 ft./lbs is the correct torque for civic's

since i put my tien springs on, my wheel has been shaking at 80mph, but only when i break a lil, if im jus leaving it alone and keeping it on 80, its perfectly fine....prolly from my shocks, stock shocks...

chances are its either a bent wheel or you have a bad tire. i had the same problem at work and one of the wheels was bent, replaced the wheel and the shimmy went away but it still had an abnormal hum down the road so we swapped the tires from another lot truck and the problem went away.
