First the cost:
$100 - 4.88 ADD front diff (Converted to non-add)
$125 - 4.88 V6 Rear
$120 - Shipping for both diffs (Could be worse i guess)
$16 - 2 Front Seals / 2 rear axle seals
$50 - 5 quarts of Mobil 1 Synthetic Gear oil
$4 - RTV gasket maker
$415 - TOTAL COST TO RE-GEAR!

Performance?
Jumping from 4.10's to 4.88's is awesome! I can actually
maintain my speed when going up hills! The 22re is much
happier operating in the stock powerband once again..
I'd say these gears are just right for 33's on an X-cab P'up
