Need Diagnosis..., Front end suspension area is vibrating while driving.. Options

[Betta-J]

So, lately I've noticed that on the highway my front area of the car vibrates. I am sure it's between the two front tires or at those locations b/c it vibrates up there. It's very sporadic and I can't tell when it will happen again. I have checked my tie rods (don't know if I can tell if they are broke or not, but physical damages or cracks I can't see), I don't think it's my wheel bearings, and my stabilzer bar looks to be in tact. I have also checked my CV rods/CV boots and don't see any physical damage (again, don't know for sure). I took my wheels off and put them back on to see if I didn't tighten them or something. I can't find anything wrong.

These are the times it starts up:
-when decelerating from 70mph (just letting go of the pedal)
-when I'm going down hills on the highway (I had cruise control on, but it's like the above--maintains speed)
-when I accelerate quickly from 70-75/80mph
-at higher speeds (at 5th gear)

Any help would be appreciated. If you can PM me that would be great too.

Is this a symptom that Celica's have? I figured the 99 wouldn't have any problems. (if anyone knows a site that lists all of the known things that go wrong with the 6GC, I would appreciate that too)

Thanks.

sounds very similar to my problem.

I haven't quite figured it out for sure but I think i'm pretty close. all my research points to bad axles.

Ill just add this, when my problem first started it was very faint and over time it has progressively gotten worse, so keep an eye on it and see if it gets worse each time you drive.
