    I have been experiencing a vibration since new that occurs at varying speeds but only when the vehicle is under a slight load , usually climbing a slight uphill portion of smooth pavement .

    I only noticed it at around 40-44 mph locally , but I was on a road trip and it occured again , fairly severely at 65-70 mph over the weekend

    The vibration seems to come from behind / under my seat , the steering wheel does not shake side to side during the vibration , but the head rests on the front seats can be felt to move forward / backward .

    I originally thought CB carrier wobbling but I set up a GoPro to film it and it does not appear to move oddly .

    This has occured through many changes in my truck from stock / stock wheels + tires to lifted and larger tires

    The common denominator seems to be the slight uphill load on the truck .

    Is there any component that would vibrate in these conditions ?

    FWIW , my driveshaft has been replaced under warranty for signs of cracking near the union at the CB .

    Tires have been road force balanced , OEM Sport alloy wheels have been replaced for another warranty issue ( bubbling )

    Any thoughts ?

    Thanks in advance .

    Actually I would torque your u-bolts, also there is a transmission mount TSB that I would look in to.

    This ^^^^

    Aim the camera at the tail shaft output of the tranny, and see if you can reproduce the issue.

    I did look for cracks in the transmission isolators and found none

    I don't think cracks are the issue, but rather too soft of a mount.

    One step at a time. That's the most probable cause given the description you gave. Get off your ass, and mount the camera for verification.

    You don't work 25 hours a day. Im sure you have 30 mins. to beat your junk, so instead of working your wrist, install the camera so we can help you.

    I would second (or third) the rear engine mount (that's what Toyota calls it even though it's not connected to the engine directly). Only other thing I would check is u-joints while you're under the truck.

    Doesn't matter how old they are, if they are not torqued correctly. Check Da Torques.

    Sure

    My vibe has been there since day one though , so unless these ones and the old ones are the problem , I'm leaning towards it being something else
