Slight shudder when accelerating from a stop

    I can't tell if it's wheel hop or something else but when I accelerate briskly from a stop between 0 and 20 mph there is a slight shudder felt in the driveline - almost feels like 3 or 4 "pulses". Once underway I can slam my foot on the gas pedal and it's absolutely smooth. Accelerating while moving onto the highway it's absolutely smooth. Truck has 1600 miles on it.

    I just added Pedal Commander and now I'm noticing it much more often (It was still present before PC).

    I've been driving FT AWD vehicles for a long time now and this is my first PT 4WD vehicle and so I'm not used to rear-wheel drive. Any ideas?

    Do you have a lift in the rear? If so it’s possible you need a carrier bearing drop. Basically a couple of shims on the carrier bearing to get your angles right. If not, I would take it back to the dealer. Sometimes I think I feel a slight shutter. But hard to tell since I have chunky tires and a loud rumbling exhaust.

    No lift...suspension and tires are stock platinum. I'm going to try putting it into 4WD on a straight road and see if I notice it.

    I would take it in if it’s that noticeable. But you know how the dealer can be, state that they can’t feel anything.

    Were you ever able to get this resolved? My Tundra just had to have the rear diff and a rear wheel bearing replaced at 77,000 miles and my truck does this exact same thing now. Dealer told me it may be the rear diff breaking in and to come back after 500 miles. It has not changed at all and I am 400 miles into the break in.

    Honestly, I now believe it's the rear tires breaking a little loose/hopping under acceleration. It's only from a dead stop and I think I was just getting used to the Pedal Commander. It doesn't do it in any other gear or if it's in 4WD. I'm just riding it out....
