Intermittent Hard Steering Problem

[miked]

Good day tsikot!

Sa kadahilanang intermittent yung problema sa steering, eh medyo mahirap idiagnose. itatanong ko na lang muna sa inyo kung sino man nakaexperience neto at ano ang naging solusyon ninyo.

Info:
1. Pitman arm style steering gear (recirculating ball)
2. SLA front suspension
3. Front suspension (ball joints, bushings, etc.) and steering rod components (except pitman arm and idler arm) replaced about 2 years ago
4. P/S v-belt tension ok
5. Fluid condition and level ok.

Problem occured, iirc, even when engine is hot when parking or maneouvering on tight spaces. konting research sa ibang forum eh sabi: kadalasan kung hindi fluid condition/level ay yung mismong power steering pump.

suspect ko yung relief valve/flow control valve which is, afaik, not rebuildable. kelangan replace the whole pump.

salamat
