It's funny you ask because this past Memorial Day my bearing gave out on my right rear wheel. I tried making it back to the house but unfortunatly it mangled the spindle. I tried to locate a replacement spindle locally here in the DFW area, but they are few and far between. The spindle runs about $35.00 and a machine shop would charge you around $100.00-$150.00 to put it on, if they can remove the spindle without damaging the axle due to the "plug weld" that is on the bottom of the axle. I contacted Ameratrail, in St. Cloud Florida, and told them what had happened. To make a long story short, I ended up purchasing a new axle with two spindles for $185.00 + shipping. Trust me, it's easier to go with a new axle. In my experience it was harder to locate a spindle and make it cost effective compared to just buying a new axle. Call Ameratrail and speak to Mark. Be sure to let him know whether or not the trailer is white (for the X-22) or black (for the S-22). He can build you a new axle and ship it within 2-3 days. Also, be sure to check the hub and make sure that it's not trashed as well. Mine was so I had to order another from UFP. The part number for the hub/rotor is 41030. They'll tell you that it's actually 41038, however this is just the new part number and cross references to the older hub/rotor. The lesson I learned from this whole thing is that I will be repacking the bearings every year before I winterize the boat. Hope this helps!
