    We’ve had 2 MBE900’s taken apart. Both thrown into the scrap bin after it was determined it was too expensive to fix them.

    Thank you very much...I was going to run them in with a 1/2 impact, but like I said I didn’t want to over do it. Thank you

    I’m sure this was a huge click click boom....

    One of our employee’s truck dropped this while hauling a truss trailer.

    He said he was speeding up, shifting gears, then boom....

    Drive shaft rolling away....

    That U-joint is only 2 months old.

    Not sure what the guy did when he installed it in his Dad’s truck after the last one snapped.

    I’ll be inspecting it tomorrow. Apparently the 2 bolts came out and one cap flew away.

    Bunch of debris collected behind a oil cooler module on an mx13. No way to pressure wash behind there. It ate through the housing to the o rings causing a leak. The aluminum was so thin in some spots it was almost pinholed through to the cooler.

    No boom.
    Driver complained about lack off power.
    Turbo spins half a turn and stops.
    It is starting to seize.
    Which engine?
    Holset turbo.
