Yes, that was one of the solutions we had. Specifically with the wheels we took angle supports and bolted them to the frame to keep the wheels from sliding if they came loose. Loctite was another useful tool, but we also had problems with vertical frame members moving horizontally which we fixed by placing bolts vertically from one frame member to another. But adding more bolts just increases one of its disadvantages: weight.
