Well the power steering pump in my grandma's 07 or 06 Trailblazer is whining. What is causing it to do this? Also the fluid smells a little burned or metallic like, is this normal?

Most common causes of power steering pump failures is overheating. Is the pump low on fluid?

Sounds like the bearings in the pump are about to go.

I'd try changing the fluid, see where it gets you. My Lincoln did the same when I bought it. Sounded AWFUL. Like someone slowly opening a haunted house door on a amplified mike.


Flushed it out, used new Synthetic RP power steering fluid, works great. I can steer with one finger now. I need to do my new truck.

Thanks to Lucas, the OP in my truck is quite good now. 45 at startup, 35 or so @2K RPMS when warm, and around 25 or so when idling. Much better.

My 97's PS pump used to whine like a supercharger, 1 bottle of Lucas, good as new.

Remember to flush the cooler as well. A lot of fluid is in there.
