'02 Silverado 1500 (4.8) w/235K miles.

This afternoon as I was leaving one of my accounts, I started to get a faint whine coming from the engine compartment.

It got louder as I pulled into my next account and left a small puddle on their drive. I will return tomorrow with some purple power cleaner and take care of it.

I backed into my drive and shut her down. The steering was still working fine.

Got underneath and didn't see where the leak was coming from so let it sit for a while. Came back 2 hours later and added fluid to the power steering unit - it was about 16 ounces low. Started her up and looked underneath - no leak. Went for a drive - couple miles - still no leak.

I don't mind changing out the power steering pumps. lines, etc - whatever makes sense - as PM. Better to do it now while she's still driveable.

But wondering if what I just experienced is a warning shot - or not.

I've gone down this road before and when the pump went - it went. Adding fluid didn't really do much.

Any input would be appreciated.

I do intend to replace it - just curious what exactly happened today - other than what I observed as described.

TIA!
