Power or no?
If power be advised that it takes special tool to pull and install the hydraulic seal that goes on driver side next to the gears. Seal is at the end of say 12 inch long 2 inch diameter hydraulic bore that piston seats in meaning you cannot mar or scratch the bore at all or rack is junk. VERY hard to work within those confines, I did it but you have no idea there. If that seal seems useable I'd leave it in place, everything else is a piece of cake. Obvious that they use some sort of piloting specialty tool there to pull and install seals at the factory.
If you have to go there, luck, BTDT.
