Lurching 40 to 50 mph slight hill

[Dave LV]

Drivetrain shuddering problem has worsened in last 1000 miles. Now happens pretty much full time. Feels like miss in engine plus unbalanced tires. After two tries, determined to be "normal".

My present guess is that it is the transfer case since it happens even when the transmission is in neutral.

I am surprised no one else is noticing this since according to the dealership all three of their loaners have the same shuddering.

By the way, lemon laws appear to be somewhat useless in that if it can't be repaired in X times (usually 3 or 4 tries), then the car must be bought back...but what happens when manufacturer says defect is "normal" after 2 repair attempts? A loop hole that needs to be corrected.
