Ok guys I have a 2010 G37 with stiff steering. I just picked it up from the dealer and they couldn’t find nothing wrong with the power steering or the rack. It did not start this until I was ran off the road by a 18 wheeler. Can you guys please give me insight on what to look at because this is not normal and it seems the dealer can’t help me either

 

You might want to check your front sway bar - It might have bent

 

Glad to hear your ok! Is the steering still straight?

 

Did you check atf fluid in ps reservoir

 

Yes the fluid filled to the max line and the dealer did an alignment for me

 

Does your steering from lock to lock feel like its binding if so pump could be going out

 

No it doesn’t feel like it’s binding but does get softer when the wheels start moving

 

Thats normal, if you take a wheel and try to rotate it on the Y axis, its not easy. If you rolled the wheel and tried to turn it the exact same way it will go easier due to lower friction.

 

You might have damaged your steering rack mine was when I got run off into grass
