yo sup everybody--

I got a question: My max pulls slightly to the right (prolly due to alignment), but at highway speeds (>70), i get these inconsistent grinding noises by the pedals. I can feel em by my feet and the pedals but not the steering wheel. This doesn't necessarily happen when im accelerating, but it seems to happen over slight dips in or bumps on the highway. about every 5-10 minutes itll act up and ill feel the vibration at every little highway dip--then itll just go back to normal.

car's dropped about 1-1.5 inches, but its been like that for years, and this is the first time i noticed the vibration. last alignment/balance was about 6 months ago.

btw, i grabbed my cellphone and recorded the sounds (as a video file). the sound is really clear about 25 seconds into the video:

i searched around and i think it could be a control arm bushing, or possibly my cv joints, but i doubt its just alignment. any clues as to what it could be?

 

...so i guess nobody knows what that noise is?

 

IDK...motor mounts shot if getting vibration?

 

i doubt its the mounts...it just seems to be more of a suspension related prob to me, but i dont know exactly what....

the vibrations happen at slight bumps and i think they're more prominent when i turn, but always when im goin 70+ mph.....

anyone else got any suggestions or have similar problems?

 

i would say its the engine mounts as well but since it only happens at 70mph + then thats ruled out. all i can think of is maybe some of your suspension bushings are possibly worn out or they are going....

 

your wheels bearing might cause that.
