Shapelock was long theorized to be an effective adhesive on plastic, but never used it in 7 years.  Decided to finally apply it to the front wheels & made a test blob.  

For this application, it was easier to use hot air than boil it & reheat it with hot air after applying it.  It melted the plastic slightly.  No amount of hammering could kick the test blob off.  After a 10 mile drive with 5 at higher speed, it was declared a success.

The repaired shaft was misaligned, there's absolutely no way to release the shapelock & we know the consequences of misaligned wheels, so they still have to be replaced.  Creating shapelock fillets around the bearing is another necessary step in fabrication.
