[QUOTE="Trick.Raptor, post: 1308911, member: 16456"] With my stock res my PS would whine and moan pretty quickly while off-road and had to be replaced at 33k. It wasn't much better at first when I went with a PSS reservoir tank and cooler. With the PSS res, the fill line was way to low and the bleed valve at the top would still spray fluid! I went from factory fluid to Royal Purple synesthetic PS fluid that helped with the whining and groaning. I experimented with fluid level filling the PSS res almost to the top and that really made a major difference. And I didn't notice any more fluid spray from the bleed valve at the top. To fix that I just put a sock over the res while off-road. It got dirty nothing else did :) I upgraded the reservoir from PSS to RPG and that was the best combo. The RPG tank was sealed with a drain hose that goes to the ground. No more PS fluid on the engine! As for my PS pump, it now has 63k on with lots of off-road abuse. At Oceano Dunes with tire pressure around 13PSI I never hear the PS pump whine or groan. At first I watched the temps and the fluid never really got hot with no cavitation. Current RP fluid has well over 40k and doing fine. I can't speak for the setup you have it will not help much if you run the stock reservoir tank. You will still get a lot of fluid splashing around inside with cavitation that causes air pockets. That is where the whine and groaning starts. [/QUOTE]
