i just did mine....the 1st side is a LEARNING experiance...and im
almost embarrassed to say it took me 4hrs to do the passenger side...
the drivers side took me less than TWO hours though
no real special tools other than some large sockets...you might be able
to get by w/ a large adjustable wrench (needed only on the ball joints
and knuckle removal).
the ball joint press and pitman arm puller can be "BORROWED" (for the
cost of a credit card deposit) from autozone(s)....if you dont return
the tools in THREE, yes THREE, MONTHS youre considered the new
owner
youll need to get the inner dust seal & the yellow (hub) oring...the
oring is about 5 bucks per side & the dust seal is about 10 bucks
from orielys etc.
there is a HUB seal that you COULD replace (i didnt) its about 50
bucks from the dealer only (apparently).
the ball joints will run you about 50-60 per side (upper & lower)...but
they come w/ lifetime warranty and grease fittings...something only
ford cant seem to find
do it yourself...or pay the dealer 900-1100 for the work (and you
still wont get greaseable lifetime parts)
