After the dealer replaced my front diff (because I split it open) my Liberty had a menacing vibration above 55 MPH. I had it aligned and all tires balanced and the vibration continues. I was told that I waited too long before rotating them and they are a little “cupped” and after a while they will round out again.. The dealer thinks the front tires were swapped during the front diff replacement. I lowered the tire pressure from 40 to 33 and now I can go 65 MPH before the vibrations starts.

My Liberty has never had any vibration before.
Has anyone else heard of or had this problem before?
How long does it take before I can enjoy highway driving again?
