Just let me say this first, I absolutely love my Preddy. Now we bought it back in November. The kid who sold it to us didn't do a lick of maintenance. We had to replace the rear hubs (JB Welded on), rear and front sprocket, chain (it had 2 master links, snapped, broke front sprocket and chain guard) and rear bearings twice now. Now sadly we have moved on to the front bearings ( inners are completely gone, outers are...eh). Hubs will not come off! Tried everything (except a puller, tried that on the rear ones, not making that mistake again). Our latest attempt is to "ride them out" still having issues. Anyone have any ideas that might help? I do not want to have to justify breaking these hubs, finding parts anymore is difficult.
