My PS pump was on its last legs:
So for this you will need:
v8 power steering pump (mine is cardon branded reman'd from advance auto which came to aorund 65 after core charges)
4 quarts dex III ATF
"pressure gasket" from toyota - will update with PN later. It's basically a double gasket U shaped crush washer thing. The cardone pump came with 3 O rings and 2 crush washers - you could use these instead but I chose to get the OEM part for 3 dollars. It is also much easier to position that two separate washers over the banjo bolt.
6 pack of beer, 12 pack if a buddy is helping.
Step 1:
Crack open a cold one
Step 2:
Drain the PS system via the return line. The suction line is on the bottom of the reservoir, the return line is on the side. Follow it to the driver side and disconnect it from the steering rack. Use a pair of channel locks on the clip, slide it back and disconnect the hose. It will get everywhere, have a drain pan ready and let it bleed.
Step 3: disconnect the lines from the reservoir, vacuum lines from the pump, remove the intake crap via the bands.
this is the suction line removed after letting it drain
Step 4: remove belt, 14mm tensioner
Step 5: Remove the banjo bolt. This might leak a little too. Discard the old double gasket thing and remove the union. it should come off easily.
Step 6: Remove the 3 bolts holding the PS pump in place. The top "bolt" is a stud threaded into the engine block with a star socket on one end and a nut. When I took mine off, the nut took the whole stud out. You may just get the nut to come off. I took the nut off and threaded this back into the block first when affixing the new pump.
Step 7: Remove the pump and pulley. Note that the pulley is splined and should come right off. Put it on your new pump and tighten down the nut. Also remove the union fitting from the old pump, the one little nut on the side. Replace the O ring on the inside of the fitting with the small O ring in the new pump box.
Here is the assembled new pump with the old union and pulley on it:
Step 8: Put the top stud back in place, line up the other 2, tighten the pump in place.
Stud in place:
Step 9 (optional): remove reservoir and clean with brake cleaner and simple green or similar.
Step 10: Jack up the front end, get the both wheels off the ground.
Step 11: replace the reservoir.
Time to flush: Disconnect the return line and plug the reservoir with something. I used a finger and had someone else helping. Point the return line downward and put a drain pan under it. Reconnect everything else. Have someone turn the wheel lock to lock while you pour 3 quarts of ATF through the system and it flushes out through the return line. Reconnect the return line and fill the reservoir up to the cold max line.
Remove the jack stands, put the belt back on. Drive around for a while then add fluid to at least the hot min line after the system has warmed up.
