My bet is tires.Death Wobble :(
wheels need balancing, sometimes shake is only evident at high speed
== == Bad Tire or Tires.
It could be your tires, have them checked.
Yes it will.
Warped rotors is the most common cause.
Loose/worn steering components. Especially the steering stabilizer shock and the trac bar.
have front suspension checked
because Jeep Wranglers are easy to flip, especially turning at high speeds.
You rotors are warped and will need replaced/resurfaced.
No,but tires out of balance will cause this. Have them balanced and rotated.
Bad tires and bad alignment can cause the car to shake at certain speeds.
If you are missing the lower speeds but still have high speed, the resistor is bad.
