I have a venture trailer. The wobble wheels are the same as EZ trailers but the inner hubs are different and stepped down. I am having trouble finding them. The dealer by me is no longer there. The real problem is I keep losing them. I put the boat in and come back for my trailer and find a roller missing. I don't think they are being stolen because it happens at different times. All clips are tight, I am careful when loading and unloading. Over the past three years I probably have replaced at least fifteen rollers. Has anyone else had this problem? I am considering using SS cotter pins in stead of the clips.
