CZBLK04SS Posted December 12, 2018 Report Share Posted December 12, 2018 (edited) I was having vibration at around that speed also. It ended up being my idler arm, I replaced the Pitman arm too.

someotherguy Posted December 12, 2018 Report Share Posted December 12, 2018 Don't assume just because the tires are balanced, that they're good. Try swapping front to rear and see if the shake changes how it feels. If it's shaking in the front you should feel it in the steering wheel.
