Default vibration from front

hello first time here just traded my s10 for a 95 bonne love the car so far but it has a weird vibration comin from the front end when i hit about 48-50 mph seems wheel oriented... any ideas? the guy i got it from said the tires are balanced possible alignment issue? if so how much am i lookin at if i take it to the shop?
it happens about 98% of the time i dont notice a pull to one side or anything... any help would be great thanks,...

Well, if it'* alignment it could be any number of things... Take it to a few shops and get some estimates, Shop around. That'll get you a closer number than we could ever do without riding in the car.

Howdy and welcome to the club. If I were you I would personally check that the lugnuts are properly torqued. I almost lost my left front wheel last week.Only two studs were holding the wheel on. Just a thought.

Check the simple things such as lugnuts, tire pressure first. If your problem only occurs during accelleration then it could be due to a bad alingment. I'm experiencing a similar problem at nearly the exact speeds you describe but would call it a wobble rrather than a vibration. The front wheels seem to shake both up and down as well as in and out. I hope to be getting the alignment today so I will let you know if this cures the problem.

If the vibration is felt while coasting rather than accellerating, it could be caused by a missing wheel weight or bent rim.

I agree with Jay. On my Grand Am a few years ago, I had a similar problem. Turns out the belt had shifted (or something like that) - had to get a new one.

Take it into a shop, or jack up the car and spin the tire at a moderate speed. If you see a "bump" in the tire, it could be the same problem.

Unfortunately, it could be any or all of these things (alignment, balance, bad tire, warped disc, etc)

You probably want to take this to a shop that will check it out for free....

if it is around 48-50 mph it could be TCC related

Don't assume the tires are balanced. Swap the front and rear as your first troubleshooting step.
