....i was headed back to dallas from austin and driving like everyone else going 75 to 80....all the sudden my car starts shaking but its not bad its just like if it were a bumpy road kinda shake but its only at 3500 or 3000 rpm's whenever i speed up or slowdown its stops any body have an idea???
edit: spelling

 

Maybe you need your wheels balanced.

 

could you tell where it was coming from? i would say check your wheels? did the steering wheel shake??

sounds like balancing or a rim that's bent...i had an oem wheel in the front that was bent at the lip on the inside and when i would get up to 75 it would shake the steering wheel and car....rim needed to be fixed or trashed...

well im not exactly sure where it was coming from it just felt like i was hugging the road and feeling all of the bumps....if the steering wheel was shaking it wasnt too bad for me to notice....but when i speed up from there it doesnt do it as bad or it stops

 

I had the same problem....Check wheel balance....

 

Could also be the driveshaft is out of balance... If the driveshaft was out of balance it would vibrate at certain RPMs.. Its very doubtful that ur driveshaft would be messed up, but its a poss...

 

Check wheel bearings. One of mine were cracked and I could barley tell except m car did not dirve as good as it should at fast speeds. I did not find out until I treplaced my rotors.

 

Here's a quick, easy way to check your wheel bearings.

Jack up wheel, suspension loaded is fine if u can fit a hand in there to do next step

With one hand, touch/hold a part of the suspension, To me the Spring yields best results.

With other hand (dominant) spin the tire. If the wheel bearing is bad you'll feel it in the spring.

Do this on both front wheels first. (easier than rear, and more common to go out IMPO)

If its Sudden onset problem I'd lean towards wheel balance (threw a weight.)
