" What's wrong with modern manual steering?

nothing - if you can find it.  'modern manual' is virtually an
oxymoron in this country, when even little cars like the bmw mini,
fiat 500, and scion iq come with ps std.

i've been thinking of de-powering my '94 cherokee's steering.

" friction. [which rules depends on speed - friction around town, aero

" remember, the pump is pumping all the time keeping the system

" a fixed-displacement pump so it's always putting out full volume even
" if the steering gear isn't using it, and it has to be sized big, to
" supply the steering even at idle, like when parking.
" 
" a variable-displacement pump could approach electric ps for
" efficiency, but not in cost or maintenance. electric ps isn't just a
" newfangled gimmick.
" 
" semi-relevant factoid: the shuttle flight control system - the rudder
" and ailerons and main-engine gimbals - were hydraulically actuated,
" and the pumps took 400hp just to maintain working pressure.
