shock absorbers for GC
 

I have a 97 Grand Cherokee that is pretty clearly in need of new shocks.
The driving it will get is 90%+ highway, but it does get off pavement
for significant distances when I can get to CO and UT. I drive dirt
pretty gently, but I want it to be capable for that use.

I'm interested in suggestions for good replacement shocks.

I live in the northeast, so rust is a factor. Are there any big gotchas
in replacing the shocks at home?
