If you had the SST to set-up the front end you would find that the top and bottom shims are not the same amount. The bottom are how you center the knuckle to the housing, the top shims are for setting pre-load. I would say your knuckle is not centered.
But then again it is a POS TG housing so who knows what could be wrong with it. I saw a picture of one on POR and the balls were not welded on straight.
You pay for quality, well worth it in the end!!
