I got a good high pressure hose from the wreckers for $65(with 90day warranty) 4 months ago(still good).
However for erratic steering - check ball joints, tie rods, bushes,bolts, steering freeplay etc.- jack up front, holding each side of tyre, move it back and forth to check. Hold top and bottom of tyre and move to check wheel bearing play. If a joint is really bad, it should be easy to find.
