Didn't have anyone to take me and warranty my unit bearing so I put on an old one I had laying around. The stub shaft is ****ed, the spindle bearing is gone and the lock out is in pieces. My question is can I have a shop weld up the big groove on my stub shaft then machine it back to spec or will the heat **** it up and make it weak? I'm going to go back with a new unit bearing, new seals, new lock outs and either a fixed shaft or a new one.
