My name is *****...

My name is ***** *****.

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

I have a 07 DTS and the power steering pump is groaning. The pressure line is also leaking (weeping) near the fabric line to steel line crimp connection. add oil and it will leak in a day. My concern is the pump and the pressure line, but the resivior tank is full of bubbles. does the return line leak and suck air on these models?

Welcome, I'm Chris (aka Moose). All experts are independent contractors here at Just Answer none are employees, we do not get a paycheck or benefits from JA. We work for the customers. I strive to provide EXCELLENT 5 STAR service, let me know what's needed from me so your pleased.

Air bubbles in the reservoir can be caused from a return line leaking and sucking in air though there is normally a leak also associated because when off that line is not under a vacuum so fluid could leak out. A worn out pump is the leading causing of reservoir fluid agitated and appearing like air bubbles. My suggestion in this case is a new pressure line and seals and rebuilt pump and new oil.

Thanks for asking your question and letting me try to help you.
