    I'm new to this site but looks like a lot of very good information. I have a new (1200 miles) Access Cab TRD Sport with a low speed (20 - 22 mph) vibration. Seems pretty slow speed to be the Dunlop tires. I've had the mechanics look at it twice and one said it may be tires and the other said the transmission was trying to learn how I drive and to put more miles on it. Seems funny to me since it always happens at the same speed either accelerating or decelerating. Any one else with a similar problem. Other than that I really love the truck.

    Sometimes it is worse than others. I test drove 3 others but didn't notice the vibration. I had them do a dealer trade to get the color I wanted and this one had the vibration. This truck is completely stock. I'm glad it has a 5 year power train warranty.

    Purchased my vehicle brand new. Drove it from the dealer to my home which is about 5 miles away. Noticed a vibration right away at low speeds. Thought it could be just breaking in, so I left it till my complimentary 600 mile service/check up. The noise is the slightest shudder and it sounded like it was coming from the driveline somewhere. The noise can always be duplicated with the following conditions:

    -truck is travelling at approx 20 mph
    -off the accelerator with back pressure slowing the truck down
    -transmission has downshifted to 2nd gear

    Service appointment #1 (Home Dealership). I advised the techs of the problem and the vehicle was inspected. Nothing was located out of place or loose. Drove home and the noise was still there.

    Service appointment #2 (Different Dealership). Noise duplicated for technician. They thought it was my after market dealer installed Toyota roof racks. Removed, drove around and noise still there. Roof racks reinstalled.

    Service appointment #3 (Home Dealership). Noise duplicated for senior technician. Microphones attached to the undercarriage with headphones on the tech. Could not isolate. Called Toyota Canada and they believed it to be the front differential. Front diff replaced. Noise still there.

    Service appointment #4 (Same Dealership as #2 appointment). Noise duplicated for senior technician. Under carriage and all components inspected and passed. Possible low auto transmission fluid, so they topped it off. Noise still there.

    Service appointment #5 (Same Dealership as #2 appointment). Noise duplicated for senior technician again. Driveshaft from 2014 installed. Noise still there. Original driveshaft reinstalled.

    Service appointment #6 (Same Dealership as #2 appointment). The Truck had approx 12,000 miles on it now. Upon inspection of the rear differential, there were metal shavings present and slight traces of rust. New rear differential installed and finally, the problem is gone.

    Good luck. I read all the other forums and was stumped.
