i find it soooo hard to believe a unit directly sent from Cardone is bad right out the box
Not likely
New noisy pump is not defective.. it's just likely has air in it.
Same for REMAN

Pumps aren't this difficult.
But you MUST bleed the air out, turning wheels LOCK to LOCK with ENGINE OFF.
This is done first.. numerous times... with engine off BEFORE you ever start it.
Otherwise you just churn up more air into foam.

Then it will take a while for tiny bubbles to surface.. may even take days.
And you'll still need to bleed it if this happened.
