08 328xi Power Steering
First, this is perhaps the best collection of advice and information I have experienced online. I am new to the site (first post), and congratulate the community on providing such a great service to owners. I am in my first BMW, a 2008 328xi sedan (79K), and love it.
Recently I suddenly experienced hard steering - not gradual, but immediate one day to the next - and the wheel does not return to center while steering. Fluid level is consistent and not reducing. I have done some searching, but have not found much specific to my model. My first assumption of course is the pump, and I am not hearing any noise from it. I have also read elsewhere that the lower steering joint assembly could be to blame, but wanted to check with a better authority here on the site.
If anyone has experience with this, I would be very appreciative of your feedback. I am planning a DIY, have a remanufactured OEM and pentosin, and am ready to go with whatever I have to do, but being new to BMW I want to get as educated as possible first.
