sometimes when i take my car to 90ish and start braking, my steering wheel starts to vibrate...you can hear a sound like something pounding again n again...i wonder if you guys have had any problems like that...i have i/e on my car...i know for sure that the rotors aren't bad because i checked them...any ideas what it could be??...i am also gettin really bad gas mileage...i dont drive the car that hard...maybe once or twice in a day...the car has 7200 miles on it

check your tire pressure for the gas mileage issue

get your wheels balanced for the vibration issue

u rollin on aftermarket wheels?? if u are check that u have hub centering rings. see if ur wheels are bent. check get wheels balanced. if ur lowerd u might have blown struts

from the looks of your profile, you are rolling on stock...if your not and you do have aftermarket wheels...then yes, check for hub-rings on each wheel

My car does the same thing. I am on 100% stock. No mods was done to the car. It only happens when the car is traveling above 80MPH. Then if I apply normal brakes, then I feel the front wheels start shaking. Do you think it's the ABS preventing the brakes from locking? My rotors and pads are like new. So I know it can't be that. Anyonw w/ suggestions?

32PSI on 4 tires, running OEM steelies, like I said no mods.

Sometimes its road conditions. What type of roads are you driving on. My car did the samething when on factory steelies and again on RH evos. You might want to check that you dont have a egg in the tire (a bump in the tire). Bring it to a wheel shop to make sure.

This may sound ~crazy~ But , are your wheels torqued to spec ?
When I first picked up my new ( 5 mon`s ago ) there was a slight
vibration , so I re-torqued the lugs (alloy 82 Ft Lb`s) .
And the vib`s were gone , but not forgoten !
If you have the "stock" tires , that may be the problem.
But , checking "lug-torque" will help prevent rotor warp. IMO
I find that the stock Firestone`s are fair at best, when my car has been
sitting around (loffing off for a few days LOL) then I drive it , it usualy
takes a few miles to get the flat spots evened out.
Before my Civic , I had a 90 Accord with Michlines and never had any "bad vib`s"
except towards the end when my ball joints were gone. Needed to much
work , so , I bought a new Civic EX
When those Firestone`s wear out , then I think I`ll buy a set of Michlines )O spelling?

Firestones suck hard...mine are already worn out in the front so i rotated em...at 7200miles only

I'm pretty sure it's because of warped rotors. This is a very typical symptom caused by warpage. How did you check your rotors to be so sure that this is not causing the problem? Warpage is not easy to detect without the right tools.

My car did the same thing, and after I got new rotors, the problem was gone.

well...my uncle owns an auto shop that specializes in japanese and european cars...i let him take a look and he said that there is nothing wrong with the rotors...i can take that man's word because he has been in the business for more then 25 years

Well have the wheel balance done next.... that's a start.

believe it or not... it could be your tranny...

vibrating steering wheel was one of my problems, and when i took it into service... honda told me i needed a new transmition...

regardless, when i got the car back, shaking steering wheel was no more

 
Rep Power: 0

Was it only during braking, like this guy? I can't imagine why the transmission would cause steering wheel shake only during high-speed braking.

I still think it's the rotors ... but hey, if you want to ignore that and look for the problem elsewhere, that's up to you. Good luck, and let us know what you find out.

yeah i've had the same problem on my specV, from what i can tell its my abs , and when i put more pressure on the pedal it stops, check your brake fluid too, cuz even though it only has 7200 miles, it could just be the fluid

if the car is under warranty then will i have to pay any money for fixing this??

Here's what my dealer said: if you're rotors are warped, then they would resurface them for free. But if they find that your pads also need replacing, then they will charge you for both the pads and rotor resurfacing, which is around $200... a rip-off in my opinion.

I ended up not even going to the dealer to let them check out my rotors. I had a very strong feeling they were going to hit me with the $200 price tag. I ended up changing both my pads and rotors to AEM and Brembo blanks for a fraction of that price. And the brakes feel awesome now.

If your problem is not related to rotors, then it should be covered for free.

Bringing this back from the dead...

My steering wheel shakes when travelling in excess of 30MPH. It's not ONLY when I'm braking, but also when accelerating. It gets progressively worse as the speed goes up. It actually feels like the steering wheel is just gonna pop out and hit me in the face one of these days...

Come on... If you get those vibrations at high speeds, WHILE BRAKING... hint the two words... WHILE BRAKING... Naturally wouldn't you look to your brakes first? If it was your tires, it would be both accel, and decel, and not only during braking. I would say that would be it if anything... Check those first.

It could be anything though if it gets worse as speed increases. Like Tire balancing... maybe you have a swell on a tire(s)... The alinment could be messed up... Tire pressure... A nail in the tire... Like I had a Saturn, and I drifted in it a lot. But while drifting, I got flat spot in my tires... especially the rear tires, then I rotated them... I didn't know what I was doing, but yea... So after 3 - 4 months, I realized this hard shaking while I drove, but it was worse when I broke. I looked at my tires, and they looked like they had cancer... LIKE A FREAKIN TUMOR!!! SO yea... got 4 new tires... IT didn't solve it completely, I had to get my rotors turned as well, but it was a combo of both... so check them tires too!

Gonna realign them next month along with new tires hopefully. I'm going to ask the honda jackbutt's to do this while they change my oil.
