Hello all. I have a 2011 G37x sedan.

Was doing a bit of sliding in a parking lot one night when we had a blizzard a few weeks ago, slid sideways into a curb that was buried in some snow. Whoops.

Bent the rear lower control arm/spring cup and Rear Lateral Link. Replaced both. Got rear wheel back in alignment (by eye) - YES, I know.
Bent inner tie rod on front end. Replaced. Also realigned by eye.

Now, I've had a very slow PS fluid leak over the past two years. I have to top the reservoir off once every winter when it starts getting noisy. And then it's fine until next year.

Anywho, I go to drive the car after fixing everything and now it feels like I have no power steering when stopped or at low speed.
I'm not sure where to start!

 

Also, yes. I have an alignment scheduled next week.

 

Power steering pump may be in rough shape from what sounds like a tough history.

 

Your steering rack under the car I know on some other cars there is studs holding it on maybe bent a stud or a bold holding your steering rack just something to look at

 

sounds like your ride took quite the abuse. its possible bent internal rod inside the steering rack. also check to see p/s pump is putting out enough pressure.

 

UPDATE: I've noticed that this problem only seems to happen at very low speed tight turns, after the car has been warmed up. Pulling out of my driveway in the morning, the steering is finger light. However, when I get to work, pulling in to my parking spot I feel as though I have absolutely no power steering. Pulling away from stop signs or red lights and negotiating a turn - no problems.

Thanks everyone. I can't imagine this being a cheap or easy fix, but perhaps I'm just overthinking it.

Apart from the night of sliding, I think the PS pump had a pretty easy life. The leak I've had for the past two years was slow enough that it would drop down from the HOT MAX level to the HOT MIN level in 12 months. Top it off, and I'd be good for another 12.

However, it wasn't until after I was playing around that I learned that donuts are extremely bad for power steering pumps.
But
What makes you think it's the pump and not the steering rack? After all, I did damage the inner tie rod.
At any rate, it's probably a combination of both.
Apparently a worn/slipping belt or tensioner could cause these conditions too.
oi vey.
