PS pump died Thursday and I had to drive the groaning elk/giraffe/heep for a couple days. Figured it was dead anyhow.
Got a rebuilt one for $110 at Partsource and replaced it yesterday. The last little bit of whine still isn't out of the system and it's pissing me off. When I refilled the system, I did it slowly with the front on stands, filled a little above the cold max level and then, with the engine off still, turned it very slowly from lock to lock about 20x each side. It foamed like crazy at first, but eventually it got less and less and there were only slightly larger bubbles popping up by the end of these cycles.
After the 20x each side, I turned it to each side and left it for a couple minutes to let the air bubbles come up to the top of the reservoir. After about 4x each side, I started the engine, still with the wheels up, and turned it VERY slowly (maybe 10x each side) until the whining almost completely disappeared...like Cadilac quiet, which I've never had in this jeep.
BUT when I lowered it back down and started to VERY slowly turn it lock to lock (only twice) with the engine on, still groaned some but got less after the cycles. Took it for a drive and it was even less after a couple minutes.
This morning, it's still groaning a bit.
SO onto the QUESTION:
Am I impatient? Or did I do the air-bleeding procedure incorrectly?
OR could I have a leak somewhere else? I can't see anything obvious. Yes, I did replace the high pressure o-ring.
