wheel bearing issues Options

[dominoslave]

For some reason i keep burning through wheel bearings on my front passenger side. Here's a timeline of the issues replaced:

October 12' - Replaced hub with junkyard hub/timkin bearing/seal kit, reused the steering knuckle that came on my car.
January 13' - Replaced bearing and seals again and was advised to order in a new hub and to get a new steering knuckle (mine was in rough shape I guess)
Early March 13' - Used a new (junkyard) knuckle, new timkin bearing/seal kit, new oem hub, new lower ball joints (both sides), new tie-rod ends (both sides), front end alignment.

I've put maybe 1500 miles on my car since early march and the bearing is shot again. I'm at a loss trying to figure out what is the root cause of this.

Edit: I have a 1994 Celica GT (10/94) w/5 speed manual
