I'm two for two now with TJ frame rot

    This is my 2nd TJ to break a control arm off the frame. This is a 2004 TJ, and there wasn't any sign of rot/rust from outside the frame. It rotted from the inside out. Already reported it to NHTSA, and I'm trying to get everyone else I know with TJ frame rot issues to report them to NHTSA as well. It's absurd for a 12 year old vehicle to have suspension components rot off.

    Wow! Almost as bad as the Toyota frames that were rotting clean in half!

    What was the mileage? Do you live in the "rust belt" and drive the vehicle in winter?

    Wow, that's crazy. It looks pretty clean too. It looks like Morris 4X4 has seen this stuff before.

    It has happened on other vehicles as well. I live in Salt Belt (Rochester), NY. The front wheels kick up road spray and throw it right into the frame rail through that control arm opening. If dirt and gravel are already inside the frame rail, it will hold the moisture in and stay damp. The salt water will be active on the metal 24/7.
    It almost looks like a fatigue break of the weakened weld also. It broke pretty much at the weld. That area gets flexed by the arm going over bumps.
    It is sad when it happens, but it doesn't mean that the vehicle has to be scrapped if you install frame repair caps.
    I do like the TJ jeeps. They seem simple and 'right-sized' for my needs.
