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

Just to clear things up, in October I went to a junkyard and bought a hub/steering knuckle assembly. At the time I only used the hub and saved the steering knuckle as a spare. It wasn't until early march that I pulled the steering knuckle from spare status and put it on my car when I had purchased a brand new wheel hub as well as new bearing, tie-rod end and lower ball joint. The car came with 18x8 +41 offset wheels, I pulled them off for the winter and installed 16" MKIII jetta wheels (which are currently installed and have been since November). I've never ran hub spacers. The 1st 2 times I replaced the bearing, I had just tightened the axle nut until i figured it was tight. The 3rd time i tightened it to 137ft-lbs which i had found at http://www.torkspec.com/torkspecmm.aspx?KI=504. And as for driving style, I deliver pizzas and this is my daily driver. I drive 600-800 miles a week. I work in downtown Minneapolis, the roads are complete ****. But that brings me back to square one as to why only this bearing has been burning out, and only this bearing none of the others. Thanks for the replys guys, sorry for the wall of text.
