    Call it, Friendo.
    Towed with my new Tundra 2,000 miles out to Utah and Colorado. It did great. 7K trailer. Right away I noticed a VERY BRIEF but VERY PRONOUNCED acceleration shudder when towing this much weight. It was a little worrisome at first but my lifetime powertrain warranty calmed me down pretty quickly. Ha.

    Back home now and unloaded I can still feel the acceleration shudder but obviously much less with less weight. My guess is that it was always there and my brain is just now sensing it after my trip, where I experienced it at every acceleration.

    Did a bunch of searching and it seems this is very common if you have lifted the truck. Mine is completely stock. Is it normal to have a little shudder on a completely stock truck due the amount of torque we are creating? If I had to guess, it's just a small case of axle wrap. I doubt it's the carrier bearing angle on a stock truck.

    Thoughts? I'm thinking of making some cheap wedges to slide between the leafs and the overload spring in front of the axle just to test whether that is the problem. I've seen others use spring clamps.

    Welcome to the forum.

    On a 2016, dealership time. This could be torque converter shudder. I would start with that.

    Hmmm...I suppose that is a possibility. Dang. I haven't noticed too many 3rd gens with this problem? I suppose I could be the outlier, however. No shudder at TQ lock-up speeds, just the initial acceleration.

    Well, it’s likely not axle wrap. Leaf spring clamps were cheap and surprisingly in stock locally so slapped some on quickly. No change. Going to drive my brothers 2018 Platinum this weekend to compare. If his doesn’t do it, the dealer won’t have much of a solid rebuttal to tell me it’s normal. Plus, my family is in double digits on buying new Toyotas from them. That never hurts to remind them of. I’ll follow-up here.

    Maybe carrier bearing....I know low miles. Early failures are rare, but not impossible. I would be really surprised if it was a TC issue.

    I may hook up my car trailer so it’s more pronounced when I go with them on a test drive.

    I had a bad rear wheel bearing. It was very noticeable around 45 mph.

    I'm going to give the driveshafts some grease this weekend, especially the slip joint. Maybe it's binding a bit. Is that something the dealers usually do when in for oil changes? I've always done my own maintenance until this truck since it's got a long warranty. I let them handle it.

    Hmmmm...I'm not finding anything about out trucks having zerks for slip yokes, just u-joints. Interesting.

    Drove my brothers 2018 Platinum today with 6,000 miles. Same thing. My mind’s at ease now. I wonder if a super short carrier bearing drop would help, even on a stock truck?

    Not sure what you're feeling. I'm lifted 3/1. I accelerate hard frequently. When I tow its 8k lbs. I don't have a carrier bearing drop.

    I don't notice any shake, shudder, or vibration under any conditions. Maybe tires? I've had vehicles that would shudder under load with different tires.

    I’m not too worried about it since they both do it identically and his is brand new. Just curious now. Definitely driveline-related. It’s likely imperceptible to most owners. When I’m not feeling for it, it’s not enough to grab my attention, unless towing a decent load. My wife commented on it last time she rode with me while towing. Just a little axle wrap. Nothing like some of the F-150 axle wrap problems I’ve read about.
