Shudder is an old issue. IIRC, there were TSB's on various years. Some was related to 2-piece driveshafts or center-carrier issues. Could be wrong, but I remember something along those lines.
And yup, the T-bars aren't intended to lift the truck with. It works, but that's not the intended geometry for the suspension.
