If it's not 1 thing, it's another!

Well I have a new problem now. It seems as if the faster I go the more vibration I get on the freeway or should I say the more rougher my car feels. So today I am going to work and I am on the highway cruising at 70mph and I go to pass a car and get up to 80mph and I start smelling rubber. During which my cars starts to feel rougher at 80mph compared to going 70mph. So I sped up to 85mph and my car really started to feel rough and I really could smell rubber then. I dont know what is happening here!

I was going to say check your balancer but, if your smelling rubber this is going to sound wierd but, see if your tail pipes ,where they loop the axle and pass your tires, are rubbing against the tire itself. If not that then go to your brakes someimes a slight brake burn can smell like rubber. I dont know dude good luck that's just where i would start.

does it make vibes or smell while stationary or only while in motion?

See, when I used to rev up the car while stationary the car felt ruff. So I thought maybe my motor mounts where going bad and I replaced them with solids. You would think the solids would make more vibration but they didnt. So I then looked at my exhaust. I tried to align the piping all the way back as best as I could. Then I noticed some difference. I didnt feel the exhuast roar under my seat anymore so there was some of my problem. So now its while I am driving only. Back when i 1st had gotten my aluminum driveshaft my car felt so smooth at higher speeds. Now I no longer even remember what that feels like. Maybe I need new hardware for my driveshaft ?? That could be one problem? I am stumped as to what exactly to do ro try.

Try this to see if you can eliminate some variables. Get up to the vibration point on the freeway (clear traffic), and slip the car into neutral and let the revs drop down. If the vibration continues, it's likely wheel balance, suspension component, driveshaft, u joints, or rear end -- but not engine related.

If it's not engine related, take the car into a good alignment/wheel/tire shop and let them put it up on the rack. They can check for worn suspension components, and they can also check the tires to see if there are any separated belts or anything like that. An internal belt separation can cause huge vibration and/or pulling without looking like much of anything is wrong. If that checks out, I'd have them do a tire rebalance to eliminate that as a possibility. If all that checks out, and you still have the vibration, it's likely driveshaft, ujoints or rear end.

can a balancer go bad, where it allows too many vibes, only at higher revs?

aluminum driveshaft!!! but you missed tha boat on those... so did i

I have an Aluminum Driveshaft.
M. Yount. I was thinking on the lines of the tires and alignment. Thanks for the ideas. I do need an alignment and I need to adjust my camber as well. So those 2 items will be my next step. Then from there I think I am gonna change out my u-joints anyways. Because I have heard of similiar problems with aluminum driveshafts feeling great at 1st then down the road the u joints needing to be changed.
