CZBLK04SS 1 Report post 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. Edited December 12, 2018 by CZBLK04SS Quote Share this post Link to post Share on other sites
someotherguy 38 Report post 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. Richard Quote Share this post Link to post Share on other sites
