What's up guys.

I've been going on against this battle for months now. I'm getting a faint sometimes very noticaable wobble when driving on the highway or at higher speeds. It's very faint in the steering wheel, you can kinda feel it in your feet. You feel it in your pants if your on the highway, as wierd as that sounds. It will come and go, I will be driving and you'll feel it, then it will go away for a bit, and then come back. Under wot don't feel anything noticeable.

Highway cruising and cruising around regular roads above 50 you'll start to faintly feel it.

Things I've changed-

Both CABs
Both swaybar endlinks
Both struts
Alignment
Both axles
Changed trans fluid wih GM fluid.

Wheel bearings checked out. Don't feel any roughness when you spin the wheel and hold the strut and or knuckle .
Tie rods checked out. No play.
Swaybar bushings checked out, no play.
As far as I know all mounts on the trans are fine. It's a 2010 TC.

I'm becoming lost now.
Is it possible something could be wrong in the trans creating this?

I recently did a clutch in the car (GMPP) I'm 99.9% sure I did everything right. Subframe is tight. Mounts are tight. Motor doesn't move with any ease...

Only issue I had was the intermediate shaft was hard to get out and back in. I had to hammer it out an hammer it back in. I know it shouldn't be like that. But could this be causing a vibration/rattle? The bearing is good on the shaft. And it's bolted to the motor.. So I can't see it being that.

If any of you guys follow what I'm saying maybe have any pointers to what I could do.. I'd appreciate it.

wheels need re balanced ? you may have lost a weight

I had them balanced a few weeks ago . I used my friends rotors to see if that was it also. It wasnt.... I looked over everything. Lol

Anyone know if there's a special way to bolt the trans mounts up or is it jus bolt in and that's it?..

The wobble is now at strictly 80mph... It's driving me insane

Only thing left to change in this ****** thing is the steering rack and intermediate shaft.

I'm gonna put my friends intermediate shaft in tomorrow (another SS TC) and see if that helps any. Other than that I'm ******* stumped and I'm gonna drive this car off a cliff

If anyone who knows anything could chime in id be greatful..

Rotating mass- axles, wheels wheel bearings. All those checked out. Intermediate shaft is the only thing I didn't check.

The wobble feels like it's a rotating not like a side to side wobble.

Anyone know if something in the trans could be doing this?

Bump?

Bent wheels, out of round tire, I've seen axles bind and cause vibration.

seeyaass

I thought it was tires but I had put a friend of mines wheels on and the vibration did not go away.

Axles are brand new

It doesn't change with throttle application? If you step down/let off the gas at the affected speed, what do you feel?
