Thanks Don, In another post you refer to a 2-man Porsche approved method. All donations go to the costs operating and maintaining this site. Fit the pressure pipe on the servo oil cooler. Or you may just be struggling to keep it highway-approved. Also check your power steering fluid.
Thanks I suppose the noise could be caused by the different fluid, but I'm more inclined to think there still might be a little air in the system after you reassembled everything and topped it up. I always remove the line from the cooler, it's easy to access and you can install extension hoses onto the fittings and direct them into pails. The pumps are tough and don't usually fail until the noise gets very loud. There are many great features available to you once you register at RennTech. Perhaps this for replacing the pump? My Pentosin suppliers had jacked up the price for the11S when supplies dwindled some cars do not like the viscosity difference, particularly in colder climates , but pricing has also reverted to normal. Observe fluid level during this procedure.
This is what I chose to do in lieu of number 12 on the list that Loren provided. I seem to recall some instructions in the factory manual involving disconnecting a hose to drain the system while filling it up top. And the Bonus is that last time I checked the 202 was a little cheaper than the 11S. All of our Power Steering Fluids are guaranteed to fit if you use enter your Porsche Cayenne into your Year Make Model selector. We completed my top end overhaul replacing the seals in the power steering pump last month.
Loren, I think those instructions don't include where they're draining it from. We prefer that guests take part in our community and we offer a lot in return to those willing to join our corner of the Porsche world. If yours is getting old, drying out or cracking make sure to replace it with a new one from Pelican Parts. You're so right iamtheari; thanks for bringing this up. After the car warms up for a couple of minutes I cannot replicate the sound when reversing and the car rides and steers fine throughout the day.
Thanks for all the info everyone. If the fluid level in the reservoir does not fall any further when the engine is briefly turned over, start the engine and let it run at idling speed. When the correct level has been reached, no air bubbles should be circulating in the reservoir and the fluid level should no longer drop. Switch engine off and adjust correct fluid level.

Often you can add fluid to the reservoir and quieten it down but usually when they start making noise they continue. Turn steering on full lock to left and right at idle speed and hold there briefly. I have noticed that in the morning when reversing out of the garage I get a groan when I cut the wheel hard. You won't get everything out, but it will look lots better. As soon as the Pentosin 202 arrives I'll flush the fluids. Disconnect pressure pipe on the servo oil cooler line leading to the hydraulic fluid tank. Power steering reservoirs hold the extra fluid needed to run your steering unit.
The tank must not run on empty while the engine is running two workers required. Do you have any further info? If they went up in size by any measure, it could be rubbing on the tire well and thus making the noise. The instructions are for bleeding a dry system. Our '99 996 had the original fluid too all based on the lack of any evidence to the contrary. I aimed this hose up making it higher in elevation than the resevoir. Have a suitable plug ready for closing the line hydraulic fluid escapes! Briefly start the engine, let it run for approx. After installation is complete, raise the vehicle so that the wheels are no longer touching the ground.
No problems if you don't as the method you suggest sounds simple enough. I seem to recall some instructions in the factory manual involving disconnecting a hose to drain the system while filling it up top. Make sure you use the correct Pensotin fluid. Fill the hydraulic fluid tank. Then turn the steering to the left and to the right.
