Sorry for the thread jack shado. Just looking for some info, I looked at the service manual and didn't get an answer. Saw some build up around this nut on the steering assembly on the drivers side while changing my oil. So I tightened it up about a quarter turn, now the steering wheel feels tighter/harder to turn. It may just be psychosomatic I hope so. As I don't want to F-up anything by restricting the flow of power steering fluid. The nut is only on the drivers side, I have circled it in this pic any info or help is greatly appreciated. I'm just wondering if I should loosen it up back to where it was before I touched it.
