Hey folks, heres a short run down on an issue that has been persistent in my 510 4 door for over a year now. At highway speed, you get what feels like a loose tire feel, a low frequency vibration that gets progressively worse with speed, and especially so with extra weight such as a passenger. I have swapped differentials, I have swapped half shafts out, rotated the tires, etc, drivelines all balanced and have new u joints. All bolts tight.
Is it possible a blown rear control arm bushing can cause the wobble? I do notice its fairly consistently the right side. I have a urethane kit for it, but i have a datsport rear. Ive heard poly isnt friendly with them.
Im pullin my hair out at this point... No obvious problems, but the vibe continues.
