You can buy the parts to rebuild you steering pump but sometime it is not worrth it. Depends on the damage.
I have the speed sensitive steering pump.
You can buy the bearing and the front seal (this will fix the front leak -if any-) for less then $20. Also you can get all the other O-RINGS and Seals for an extra $10
You have to check the interior of your pump (the rotor and the plate). If there are scratched (impurities in the steering fluid) you are looking to spend more than $75 for parts.
On the other hand you can buy a used one (with extreme limited waranty-probably 30 days) for $85.
I found one at
ACTIONAUTOR@aol.com. This is an e-mail from a wreck yard (THANKS RICK @ Action Auto Recycling 888-535-0063 TO PLACE YOUR ORDER ). You can also browse Car-Part.com This is a good site for any (used) need.
Good luck!
