The connections between the metal and the 2x4s is what's wiggly. It's held together by screws.
I'm thinking maybe If I took it apart and replaced the screws with bolts it would do better. Maybe I need to put bushings in the 2x4s to put the bolts through? (I know bushings are usually used with rotating parts, but they would also help keep the bolt stable in the 2x4.) Suggestions?
Stop messing around dude! Get two eye bolts(PER SIDE) long enough to fit the 2x4 edgewise then drill holes through the 2x4 drop the eye bolts in with the eyes on top strip off the chain ring from the wheels then stick the axle through the two eyes bolts each side and install/tighten the nuts.
When done the whole assembly will be a lot stronger. Mine can carry a 300#+ load easy.
