Steve,
If you are talking about the valve assembly o rings, as John stated earlier
thats a no brainer except for the tedious part when you have to tap the
stupid thing up or down slightly to center the pressure between left and
right.
If, as I surmise, you are talking about the nut and screw combination on top
of the dome shaped cover where you make the backlash adjustment thats almost
as easy. There is a seal under the locknut where you do the backlash
adjustment. There is also another much larger o ring around the cover
itself. If its leaking around the larger diameter of the cover then you
have to take the cover off, if its leaking around the nut and adjustment
screw then all you do is back the nut off while holding the screw from
turning ( it will probably want to turn a bit but dont sweat it ) and then
replace the o ring.
Ma mopar used the same o rings and seals in the constant control boxes for
about forever and a day, the worse thing is that you may have to get a kit
from a Chrysler parts dept if you cant get them from your local parts store.
And fwiw, if you have to readjust the backlash on the steering gear its a
snap. You do a basic setting with the engine off, turn the wheels from left
to right a couple turns and then return to center. Then with the engine on,
you tighten the screw until the backlash is just gone, then tighten another
3/8 to 1/2 turn and torque the lock nut.
The FSM shows this very well and describes it in section 19.
Go for it, its not hard!
