Shaking from 65mph-90mph

[ENDEE666]

Front end shake & vibration. Thought it was subframe bushings cause they were making noise. Changed them out. No more noise but still shaking. Below 65 or so its ok, once I break that it shakes. Yet it smooths out above 90 or so, a little at least..

Tire balance or alignment is what I was thinking. Maybe a tie rod or something too. I did use fix-a-flat recently. Did that maybe throw my wheels off balance if i accumulated in one spot? Whats your thoughts?

Replace the tire you used that horrid fix-a-flat on, it is out of balance.

Would getting it balanced cure it as well? Tires are in good shape & I dont wanna spend money on this car right now.

I would never put fix-a-flat in any tire I do not intend to replace soon. It is what I call 'last resort' solution.

In short, Id replace the tire.

You can try having it rebalanced, but I bet they will have fun trying to balance it.

After being an employee at a tire shop I can tell you balancing will be almost impossible. The fix a flat stuff stays liquid in the tire. Only a small part actually hardens. On the plus side if you break the bead with the tire still inflated and that stuff inside you can spary it close to 30 ft. Kinda funny seeing a red wall turn green. as NotSoSLowSHO said, replace the tire, just make sure they do a good job cleaning the wheel, that stuff is a pain to clean off.

If you want to salvage the tire, remove it from the wheel and clean all the fiz a flat out and remount the tire to the wheel. Then have the leak/hole properly plugged prior to getting it ballanced and you should be good.

Some worn suspension components can increase vibration at higher speeds too. My front strut rods need new bushings but I found in replacing the rear struts and end links I eliminated vibration I felt in the rear. Just an FYI...

Then you shouldn't have bought an SHO.

Seriously, replacement of the tire would be the best [not to mention safest] action to take.
