ARB bumper shaking?

[bcripe]

Hello folks, I tried a search but no luck. When driving down the highway (or any road) my ARB shakes independently of the car. Is that normal? On my 80, the ARB is rock solid. I looked it over and doesnt seem to be any loose bolts, etc.

Thank you!

Yes, pretty normal. TJM's shake even more... the body mounts are absorbing a lot of what you don't feel, but depending on speed & other factors the bumper can get its own little vibes going, which you can definitely see in reference to the more stable hood.

Is normal, I have the same.
I had to re-align the bar again after a 4WD trip.
