vibration when turning wheel at stand-still

[mtnman]

Well, the grOan was back this morning ~15 f. It was similar to before.

Now I realize that I didn't rev at all. So since I am taking it in for oil/ATF drain/fill I'll just have my guy flush it properly.

So now my question is, how long does a pump last with air in the system ? I am aware of cavitation that can occur with pumps but not sure if that is possible in this application. Is it just annoying groaning or is it something that can damage the pump?

Just turn the wheel from lock to lock 4 or 5 times and it will bleed out the air.

My only hang up with this method (although its in the service manual too) is that the pump will be running dry for some time even if its for just a few seconds. I am not convinced thats without consequences. It will undergo excessive wear during that time and those wear contaminants are now in the fresh fluid. Its probably the equivalent of wear occuring over several thousand miles under normal operation with fluid.

And this happens not only while draining the old fluid but when filling up the new fluid too (step 6). The reservoir will run dry and you keep adding new fluid until the whole system is full.

Does anyone know if the '01 psf reservoir had a filter ?
