    Trek ABP service - How do I remove this bolt?

    I need to service the bearings. How do I remove the pictured bolt/axle? I already removed the nut. It seems like it should just slide out, but I've hit it with a rubber mallet with no luck.

    Yeah, it's stuck. Drift it out or keep hammering on it. Maybe spray some penetrating oil to try and break up the corrosion that's keeping the bearing from releasing the pivot.

    Enjoy that!

    It appears as though the bolt is keyed to an allen bolt, maybe an 8mm or so on the inside. Could it be the bolt is threaded onto the frame tab?

    Thanks, guys.

    trailbildr called it. The drive side bearing was seized to the pivot and came out with it. I never got it off, but I was able to clean & repack the bearing and press it back in (which was actually easier than getting it out). All is good.

    Ciclistagonzo, you need to hold the hex when you remove the nut to keep the whole assembly from spinning.
