Howdy all,
I have an 03 Yukon XL 2500 Denali with a 6.0 L engine and 260k miles. I've had a slow power steering fluid leak for a couple weeks (requires a half-pint per week or thereabouts). I finally had time to take a closer look today, and it appears to be leaking between the hydro-booster and master cylinder.
I've found quite a few similar issues on forums around the web, but the common answer is that the hydro-booster needs to be replaced and there is no other option.
My question is, if the leak is between the two components, is there a gasket that can be replaced? And if not (which seems to be what I'm finding), why? I found one comment discussing that the connection between the two isn't sealed, and is designed to leak fluid if there is a leak inside the hydro-booster. Is this the case? I've also seen conflicting things on whether or not rebuild kits are available for the hydro-boosters. Finally, searching for hydro-boosters online I can't seem to find the parts on any of the normal auto parts dealer websites.
I'm a master plumber and home builder who has returned to school to finish my mechanical engineering degree. I'm good with my hands, and am reasonably intelligent, but don't have lots of auto-mechanical experience outside of alternators, water pumps, etc. It seems this would be an easy replacement. Is that true?
Thanks for your time!
