Hub outer race seat.

Here's one for all of you !!! My 68 dart has 9 in. frt. drums. stock height. centerlines 14x 6 on frt. Suspension is tight ,no excessive camber. The out race seat on the rt. frt. is stretching , making the race bearing move around inside. Iv'e replaced bearings and races twice, staked the outer race well!! Both times and within 30 miles city driving, it's making growling noises and I can feel it moving when turning. Also the tire/wheel is leaned in when parked. Why ???? Is this common ?????
