Steering seem to be loose.

Car is stable at low speeds, no steering issue.

But on the freeway, when I get into ruts in the road I get the sensation that the car is suddenly moving hard to one direction, then to the other direction.
Like "falling" into such ruts or grooves.

I'm having this issue since last summer.

During winter month, i've change the following part.

• Steering damper
• Front Lower balljoint
• Front Upper tab with balljoint
• Front and rear shock (KYB)
• Steering linkage
• Outer tie-rod
• Inner tie-rod
• + alignment

...but still getting that problem on the highway.
