How many tow miles, what's the weight of the tow and how many hills, mountains and hard stops? All these things matter. Blue Ox hitches tend to wear a lot at the pin holes where the hitch is connected to the tow, and at each point where there are bolts holding arms and connections. We've seen wear in these areas so bad I've had to shim the bolts with steel shim stock to reduce clearances to acceptable levels. Of course some places are impossible to add shims to, so these pieces need to be replaced. Just adding new plastic washers and tightening bolts gives the appearance of solving the looseness problems when they don't.
