Steering pressure not constant
 

I have looked high and low for an answer to this question but I have not seen anyone have a similar question.
As I take a turn I can feel the steering wheel slip (Slightly) as though the pressure goes from normal pressure to a lighter pressure. It doesn't make the drive unsafe but I really don't like not having a solid and constant feel.
What I have checked so far...
--Replaced the serpentine belt
--Fluid is between the min/max line
--No leaks
Could this be in the rack and pinion? Maybe the shaft sticking? Or could there be air in the system? If so, how do I purge the air? Does anyone have any thoughts to this annoying issue?

Many Hondas have a problem w/ a leaking oring on the suction return fitting at the pump. This allows air to enter and causes noise and variable steering boost as air "softens" the hydraulic fluid. If you hear whining/roaring noise at times from the pump, this is highly likely.

It can also cause PS fluid loss as the foam will overflow the PS reservoir sometimes when you stop.

good luck

Is this on some kind of Accord? Not all years 1976-2013 are all the same. There's some years that have speed-sensitive steering boost.

Totally with TX and Jim.

My two cents, if the miles/years are do or someone has done work on the PS system before, a PS fluid flush might be needed.....Honda's are VERY picky on PS fluid and Trans fluid. So the point, be sure that Honda/Acura approved PS fluid is used.

sounds symptomatic of a bad rack/pinion too...what year/engine is it?
