Power steering pump issues after coil over conversion

I have a 2001 Mercedes Benz S 600 V12 I did A coil over conversion with strutmaster struts upon doing so my power steering pump started making noise and failed soon after thought it was just bad luck ordered a new power steering pump lasted about two days and did the same thing as the first one the top where is the bearing out until it is just flopping free I have read and some other forums there are a few guys They have done a few different things I am wanting to see if there is just a way to buy a line to research it back to the power steering pump a guy name cowboyt somewhere has did it before but I cannot find his forum

I have the same car same year and and I just finished the non ABC pump swap after the same conversion. Tenzero has a great thread below for the pump conversion. Just delete the ABC system altogether by doing this.

Have you noticed a power steering fluid leak ? Maybe you or the person who did the conversion damaged something while working on it because I don't see how the power steering system and the coilovers are linked. Maybe they are though, I'm not pretending that I know everything about it.

It's a shared pump for the suspension/steering, if you run the suspension side dry it will fry the pump.

You can re-route the line out of the ABC side to the reservoir return and it will just pump fluid with no pressure and last as long as any other P/S pump will. Or you can swap to the non-ABC pump with custom brackets or using the OEM brackets for an SL65 Black Series.

Some info and links here. The part #'s I posted are for a V12 without ABC, the only application that does this I'm aware of is the SL65 Black Series.
