Ahhh here we go...
Check the info here, it is the actual Vibration and Diagnosis info I was looking for.

Vibration Diagnosis and Correction - 3800Pro.com Forum

Thanks, ill check these out today during my lunch hopefully ill have time when i get home to get it off the ground n check everything out

I really think the next step should be to have them balanced on a road force machine as suggested by Tech II.

Around How much would that cost?
Im honestly beginning to think its in thr front because i havnt touched the front suspension since i bought it... Oh if i didnt mention it, its a 03 my friend now has my 97, and it upsets me to say that. Wanted to be flashy flashy and put 22" rims on my old girl and blew the motor smh

I think it is from 60.00 to 100.00 for all 4 tires, depending on where you go.

Ohh ok, so this is not the 97', either way the way to diagnose the issue via that link I posted should still be valid.
I know about being flashy, I dropped like 8,000.00 on a competition stereo system years back, and I still needed 4,500.00 more in amps and extra batteries, the weight of the speakers and box were killing my gas mileage, lol
We live and learn!

It could be something with the front suspension, but really when you have the vibrations only at 55mps and above, it is normally and issue with the tires, or tires/rotors/drums combo that is off balance, I am pretty sure that is true for about 90% of the time.

If it were your outer tie rods you'd feel it in the steering wheel, at least I did when both of mine were bad.

Alright thanks, think youve just put me on to something their maybe its the back rotor, when i reverese n lightly hit the brake i have this loud humm i would call it when lightly applying the brakes.. sounds as if its coming from the rear right wheel... Im gonna have to pull it off, maybe that hub is bent pissibly to, because i recently changed the studs on both rear hubs, maybe it got a little bent in that processs

That is possible, hopefully that ends up the issue, and then you'll know what to do so you can get it fixed, which would be to find out if it is the hub or rotor, and either replace it, or see if a road force balance will be enough to fix it.

Hopefullly, ill pull both rear rotors off and just take em and have em balanced and see if that fixes it... Also ill see if i can spin the hub fast enough n see if it has a wobble to it

Good luck, let us know how it goes!

Looks like much of the car has been taken apart over and over. Before doing more, maybe try throwing the spare on one corner at a time and see if the vibration goes away? Bent rim seems much more likely than struts or bearings or rotors or etc. . . .
