Shakey Ride Above 80 MPH

I just replaced the outer tie rod ends and got an alignment done. I also have 2 new front tires. When I push the car above 80 it starts to get a bit rough. Anyone know what this might be?

your wheels could have been balanced wrong when they put the new tires on, i would try getting them rebalanced and hopefully thats all it is.

Is your tire pressure good?

Does your car idle roughly?

The tire pressure is good, the car idles fine, There is no sign of issues before the 80 MPH mark.

In that case, I think you would need those wheels re-balanced again.

sounds like a wheel balance issue to me to since it only occurs over 80. does it go way by the time you hit 90? that's what mine did before i got it rebalanced.

I didn't try to push it over 90 when I felt the shaking. I will take it back to the tire shop and see if a rebalance fixes the issue.

I will let everyone know.
