I unpacked the RidGiD RT 14000 and started assembling it, there were two left rear axle carriers in the box. Left and right are needed because the holes for threading the axle match. This really highlights the quality control in ReadGuide. I'll call them tomorrow and see what's good. It took me weeks to rummage around in the big hardware stores and on the internet. I chose and bought Ridgid and the delivery matched the project. Failed project due to Emerson/Ridgid quality control. I wonder what other problems I might run into. one
