Well as for the wheels; they did a balance on them, and when I said that I still get an off and on wobble with steering the mechanic said it was likely the wheels were out of shape. He also noted that since there was a LOT of counterbalance weight used on the wheels that this was an indicator of bent wheels as well.

I looked at discountdirect but it seems just to link to other wheel and tire sites. I still haven't found anything cheaper on the web for 5 wheels + tires mounted and balanced.

And as far as the idler and pitman arms go, should I just replace them and upper control arm shafts, or is it worthwhile to do more before I go and spend money to have it re-aligned?
