I just installed a new power steering pump on my truck 5 days ago. It whines every time the wheel is turned. When the truck is cold it is fine, no whine. I turned the wheel lock to lock several times to burp any air out but it hasn’t gotten any better.
Do you think it’s a bad pump?

Give it a few weeks. That style pump has a break-in period and the low-fluid whining noise at all times is normal during that time.
