Bad Vibrations

[drift_raptor]

So when i get going over 70/mph my car starts to vibrate and the faster i go the faster it vibrates. what could be the cause of this?

 

[ROOKIE1]

Alignment - pulling right or left . Steering components . Low tire pressure . No other symptoms ?

 

[drift_raptor]

no the car drives strait as an arrow tire pressure is fine i keep on that just had the wheels ballanced thinking that was it. but the probles is still there. they said my left axel was bad i figured thats it. thought i would get some other ideas.

Check your motor mounts for a broken one, but Im going to say the most likley cause is a broken band in one of the tires.

+1 for broken belt in the tire. I couldnt find my vibration last week until I put the car on stands and running in 2nd gear -- then you could see the right front had a high spot. I thought it was wheel bearings or tie rod ends, but nope just a bad tire.

Yes definetly check your tires for a broken band, and if it is, post up what type of tire it is, it would be nice to have a bad tire thread or something on here...

Could be axel but check if tire is out of round (broken band, etc). It can be balanced but still out of round (a poor shop may not check this). Just jack wheel up and put something 1/8" under bottom of tire, turn slowly, and watch if the gap varies a lot or touches it. You can also replace front wheels with rear ones to see effect. A very rare case I had once was the mag wheel lug nut holes were slightly off their circle pattern - it took 5 years to find that one because they always balanced it using the center hole so it never appeared out of round and always balanced!

I was going to say driveshaft untill I saw that you were fwd. Is it a humming vibration or a violent one?

It could be a wheel bearing.

at 70 mph its mild anything above that it gets increasingly violent. like things start shaking around in the cabin. Its kinda scary

Does the steering wheel shake back and forth or wobble (little/lot)? If not check motor mounts. If yes, there's all kinds of things (although some can happen even without steering wheel shake): suspension (ball joints, bushings, bent members), bent axel (half shaft), CV joint (although these usually make noise at low speed turns), wheel bearings, slightly bent wheels, tires, loose tie rod ends.

My guess would be motor mounts too

 

[drift_raptor]

damn guess ill look into the motor mounts....as well as the tires, and everything else.

 

[Talonracn50]

I still would check the tires and the tie rod ends.

 

[drift_raptor]

Turned out my tires were the culprit, put new ones on and the problem is resolved thanks for the tips guys.

 

[WILOWNU]

And what kind of tires were you running?

Old lumpy ones.
