unfortunatly dimpling the hub is not a very good idea as it is a load
bearing item and the disturbing of a machined surface can be an introduction
of a surface irregularity that can become a crack. also the tiny amount of
raised metal from dimpling becomes the load bearing surface and will
eventually either get worn away from the bearing not fitting corectly in
it's bore or it will get pounded back during use resulting in a loose fit
once again. the loctite stud and bearing mount material is a reasonable
save (as it will support full circle) but the best repair is a new hub (be
it new or used). do not go out and play speed racer with it untill you fit
a replacement that has not had a bearing spin in the bore(causing the loose
poor fit).
