I just replaced the load leveling struts with Bilsteins and strut assemblies from another 7 series car. I looped the hydraulic lines going rearward so the power steering relief valve would not open and heat up the system oil. It Worked perfectly for 2 weeks, now I have noticed a marked increase in the level of effort required to turn the steering wheel. Did i plug a filter? Also what type of fluid does this system use?

The PS in my wife's '93 740i is similar to what you describe. It takes some exotic stuff called Pentosin or something like that. ~ $20 / liter. I hope you didn't put ATF into it if it takes the Pentosin.

Good Luck,

Phil
