My stang has a vibration between 70 and 80 mph. The steering also feels loose. It's been aligned and the wheels have been balanced.

 

Mabey driveshaft?

 

I put a new aluminum driveshaft on it. It did it with the old one and the new one

 

Wheel bearings?

 

Worth a shot. I haven't replaced them yet so I might as well.

 

I am also going to replace my wheel bearings.I am staring to notice a vibration arround the same mph that you are describing it is f***ing irritating!

 

thats an easy one.... just stay under 70mph or over 80 mph.just kidding. i had the same thing on my car and it took me forever to find it but it ended up being that the tires werent balanced correctly. even though i got them balenced, they didnt do it correctly so i had to have it done again.</P>


hope this helps, Dan</P>

 

it could be your driveline.

 

i have the same problem, i just had 3:73's put in my car wednesday and now the whole car vibrates about 70-75. im going today to have my drivesaft taken out and balanced, hope that takes car of it.

 

Fordgasm, now that is a funny handle
