01 pathfinder steering

[maxrev]

hey guys I'm new to this site. and don't know a whole lot about nissans in general. I've got a friend that owns a 97 pathfinder 2wd 5 spd and she has a sharp jerking steering issue on the freeway. pretty scary going 70 mph when all of a sudden the car just jerks left or right especially in turns. I've only noticed this on the freeway. I've never felt anything like this before is it the power steering pump malfunctioning? the problem is intermittent but happens quite often. any help would be great thanx
