Help, steering issues

[jahayes10]

Hey there new to the forum.
I have a 2012 maxima that has been experiencing tight steering at slow speeds. I've had the power steering pump checked and the fluid levels and both were fine. I've experienced the tight steering 3 times in the past 2 days. The first time I took it to a shop to have the pump looked at and after coming off of the rack the steering was back to normal. The second time the problem seemed to go away after driving it about 10 mi at speed. The final time it was still tough after driving it 10 mi, but as soon as I went over the bump in my driveway the steering was back to normal. I am at a loss for what this could be and would really like to avoid paying Nissan's costly "diagnostic" fee. I do know I need a new strut on the RH side but I do not think this could be related, then again I'm no expert.

is the car not under warranty anymore?

You might jack up the front end and look for leaks
Have a friend look under the car and cut the wheels back and forth
and see if anything looks suspicious
Shake the front end to be sure its not something else
Make sure the belt is tight and the belt tensioner is working ok
