I found an easy way to repair the AS38237BL-AF - WHEEL TUBE ASSY for Bravo and Viva. HEX Price approx: $75.00. The drive side pin holder in the tube (pin that goes into the cover) wears out and the pin in the tube side flops around.
Just remove the pin, cut off the roll pin in the pin flush. Buy a 3/8 inch close nipple. Glue with high strength industrial epoxy the nipple into the tube. when dry insert the pin (flat side in) into the nipple and tap the pin to the right length.
