The Power steering pump is leaking on my car. It drips about once every 3 secs. Looks like its coming from where the two hafes go together. Just wondering if I could fix it. Or so I just buy a new one. Also how much would one be

 

The only "repair" you might be able to do is to pour some Power Steering Stop Leak in, and hope it works. All that stuff does is swell your seals up, so if it's not a seal problem, then it won't do much for you. Power steering pumps don't tend to be servicable parts, but I expect they are commonplace in the junkyard.

 

You can get a rebuild kit at most parts stores, but as said above...they are very obtainable through your local boneyard!

 

Two halves?
You can get a new reservoir at most parts stores.
