Hey there honestly never rebuilt one but it might be fun to try. But I would suggest just do a google search I just did and there like 65.00 that's shipping included on carparts.com.thats assuming what type of pump you have. Power steering pumps are hard to kill in my experience u might check your local pick a part last time I bought one it was like 10$$ and I was able to pick a few odds and ends up for my C-10.
