Hey guys, I did the brakes on my 2010 e92 335i a little while back and a few days after that I noticed that my steering had gotten pretty stiff. I doubt the issue has anything to do with the brakes but while changing them I was turning the steering wheel back and forth with the car off to get good angles to work on the calipers. I didn't look into the issue too much at first and then one day added a little bit of power steering fluid to the fill line because it was about a centimeter too low on the dip stick. It seems to be marginally better but still not the way I remembered it being. I drove it for the first time in a couple weeks today and when turning the wheel at lower speeds it has a very inconsistent or choppy stiffness while turning the wheel and sometimes resists being straightened out when coming of of sharper turns. It sounds like the steering pump is working properly when pop the hood and listen as I turn the wheel but I'm pretty stumped on where I should start my investigation whether it be the power steering pump or steering shaft/ u joint. Any input or advice would be greatly appreciated!
