I've known I had a slow leak from my pump for a while, but a few days ago my steering wheel started getting stiff whenever I cornered hard. I decided to check my level and it was definitely low and my leak appears to have gotten much worse. I stumbled upon this thread and am now considering rebuilding it myself to save money but it seems that not all the O-rings you guys are using are the perfect size? If it's just going to leak/have problems again a few months down the line I'd rather just get the rebuilt pump but $9 worth of o rings compared to a $135 pump is pretty tempting. Anyone else have feedback on how their rebuild is holding up?
