REMOVAL
(1) Disconnect battery negative cable
(2) Raise vehicle.
(3) Vehicles equipped with A/C:
(3a) Using a floor jack or jack stand, support the engine and transmission assembly so they will not rotate.
(3b) Remove the front engine mount bolt from the insulator and front crossmember mounting bracket
(3c) Lower the front of the engine, rotate the engine forward, allowing easier removal of starter motor.
(4) For easier servicing, do not remove the wiring from starter at this time.
(5) Remove two bolts attaching starter to transmission housing
(6) Remove starter/starter solenoid assembly from transmission housing. Position the starter to gain access to the wiring connectors.
(7) Remove the battery positive cable nut and remove the battery positive and generator output wire from the starter
(8) Disconnect push-on solenoid connector
(9) Position the starter vertically such that the pinion end faces downward.
(10) Remove the starter through the bottom of the vehicle. Move aside A/C plumbing as necessary.
I think you have to replace the whole starter and not just the solenoid, but I am not positive.
