Power Steering Pump Rebuild
Power steering pumps are expensive to replace, so I decided to attempt a rebuild. The rebuild kits from the dealer are about $32 and have new gaskets and seals.
Remove the high pressure and low pressure steering lines. A long extension
works great for getting to the banjo bolt.
Loosen the tensioner bolt and remove the two bolts holding the pump in.
Once the pump is out, remove the three bolts holding the reservoir.
Use something to hold the pulley from turning while removing the bolt.
Remove the pressure union and the spring dealie.
Remove the rear housing exposing the guts. Make note of which direction
each piece is facing so you can get everything back together properly.
Remove the old shaft seal and use a 24mm socket to drive in the new seal.
Clean and re-assemble the various parts.
Install the new O-rings and bolt up the rear housing.
Re-install the spring and pressure port dealie.
Install the new O-ring and bolt up the reservoir.
Bolt up the pulley and put your good-as-new pump back in the truck!
