Hey all, I am having an issue to where I get a bad shimmy when hitting bumps and it's ONLY happening when turning LEFT when hitting them. I can recreate it easily by one specific bump on my way to work daily. Whenever I am turning right it does not do it at all and stays very tight and turns fine.

It almost acts like a mini death wobble but only lasts about 1 second after the bump then goes back to normal. Maybe like the axle is shifting??

I currently have these installed:

Fusion 4x4 2.5T Drag Link and Tie Rod
Upper and Lower Adjustable Control Arms
3.5" Rough Country Shocks and Springs (Upgrading Soon)
Rancho Adjustable Track Bar
Geometry Correction Brackets for CAs
Yeti Sector Shaft Brace
TeraFlex HD Balljoints
35x12.50r18 Mud Terrain Tires
Fox 2.0 TS Stabilizer

All installed within the past year. Drag Link is NOT flipped

Castor is Roughly 7 degrees when I measure it. Was aligned not long ago with a slight toe-in. I checked toque for everything I can think of and all is ok. I do have an Aluminum Steering Box that I adjusted myself and feels like it steers fine, that said I have a Steel Box on hand I can install if this is possibly the issue?

Tires were just Rotated and Rebalanced Last Week due to thinking that was the issue and it did not fix it.

Any thoughts are greatly appreciated. I am going in a couple weeks to get it completely setup alignment wise, they are gonna measure everything possible.

Thank You!
