    [​IMG] Tacoma buy back insider info straight from DANA.
    Alright so everybody hear knows about the buy back, recall whatever you want to call it. Like many others my tacoma was bought back. Long story short Im in a Weld 400 class this semester (Fabrication of Alloys) and we got a brand new instructor for the class and guess where hes been working for the last 8 years DANA corp as a Weld Engineer and Robotics tech. Today were talking about alloys and how certain elements are added for their deoxidizing properties; silicon, aluminum etc. And he asks if anybody knows about the tacoma issue and 2 of us in the class had our Tacomas bought back, needless to say it ended up turning into a half hour discussion and this is basically what he told me. The frames were being welded/assembled in the plant in Texas and then Shipped to California for the E-coat rust preventive to be put on and final assembly. He claims 2 main problems for the issue, 1. is that when steel is welded the backside, or in this case the inside of the frame rails the heat affected zone forms an oxide that causes the E-coat not to stick to it if not properly cleaned off with an acid bath which he said the California plant did not have. This is why the areas around the leaf springs were a problem area. 2. The Texas plant was using a new type of wet lubricant to keep the frames from rusting while traveling from Texas to California where as the frames coming from Japan were coated with a dry lubricant. The wet lubricant being used apparently also contributed to the E-coat not adhering to the frames well. I dont know if this has been covered before or not just figured I would pass this along.

    had me scared there for a minute. But mine isn't one of the year models being recalled. Thank goodness but it would be nice to have a new 2nd Gen.
