I hate receiving refurbished items but thought I'd give it a try. The old pump is leaking out from under the mainshaft. Took it off and installed a new pulley on this new assembly using a 7874 pulley puller and installation kit, by far the most time consuming part of the repair. Put the new pump back into the jeep, started it, spun the wheels back and forth, the power steering was normal, turned it off, done! Clean up before the test drive, start the engine and the power steering fluid is sprayed all over the bay and 5 feet! Leakage from the central shaft! Now I have to do this job again tomorrow with parts from Oreilly Auto Parts locally.
