Hey folks,
       My front tires are cupping pretty heavily, most of the wear is on the
outside edge of the tread.  The driver's side tire isn't too bad, just
rounded on the outside edge.  The passenger side is wearing heavily on the
outside edge.

I've had the alignment done recently, and many times in the past.  Still, the
tires wear in the same way.  The upper ball joints were replaced on both
sides a few years ago.  All other parts are original.  The guy at the shop
said he couldn't adjust the caster, because he couldn't get the nuts
loosened.  The rear tires are wearing very evenly and much more slowly.  I
keep the pressures pretty high, like 45/50 psi.  Tires are 185R14, reinforced
sidewall, load range D, max load 1875lb, 8 ply radial.

So, the question:  anyone have any idea what is causing this?  I guess I
should add that my shocks are original (18 yrs - 268,000 mi), if that makes a
difference.  Any info or similar experiences will be greatly appreciated.
