More Vibration.....
 

The car basically shakes violently at speeds of over 70 mph ne know what the deal is?

from what ive heard , check tire ballance and wheel barings

I have similar problem and did all that plus suspention replacements. And still don't know what it is.

Tomorrow my bonnie is going to the Daler I can't spent anymore on tools or parts that cannot solve the problem.

any sugestions.

yeah im just gonna have to take her in cuz i cant figure out the problem by myself

This could be a ton of differnt things. We need more info to help further.

Some common possibles
Tire balance
Broken belt in tire
Bent rim
Very bad alighnment
Warped rotors

See where I'm going..more info would steer this topic into a general category to have you look at.

My dad's Chevy lumina did something similar, shock pretty bad over 50 miles an hour and got worse as speeds increased. He had New Ball joints put on each side and New tie rod ends on the front and that fixed the problem.

Classic case of worn front end parts ending up in bad alignment. ;)

The first thiing I'd try is rotating my tires. If the shake moves, then it's a good bet that a rim is bent or tire tread is starting to separate.

If the tire is starting to separate its tread, usually the car will 'waddle' at low speeds. Oddly, I've noticed that tread separation vibration peaks around 45-55 and then decreases at higher speeds.

Sometimes, tire cords will start to do weird things inside the tire and the tread won't bulge. I had a tire shop tell me a story like that... they had the company reps come in and everything. Finally, they isolated the bad tire by moving the tires around on the car and then replaced it.

As Bill said tho, could be many different things causing your trouble. This is only one suggestion. I've had more than my share of tires separate on me. Not sure why, but mostly due to age. I don't wear them out fast enough I guess.

Before rotating tires..I'd probably jack it up and check for worn parts.

We need more info to suggest a good direction.

tires were rotated about 2 weeks ago, i just replaced the rotors (bendix), the tires definetly need aligned-the car drives to the right without touching anything so that has to be part of the problem, and finally i have jacked the car up to replace the rotors and pads and i did not see any visible problems i think im just going to take it in
