Hi guys.
It's getting cold now up here in Canada......
....And my power steering pump is quite noisy when I first start the car in the morning (brrrrrrr!). After warming-up for a while, the noise disappears.
I checked fluid the level and it's fine.... My guess is that the noise is due to cavitation (air bubbles) inside the pump caused by some worn O-ring(s), which is amplified by the cold weather....
Has anybody experienced this before??? What was the fix
???
Thanks for your help.
