Default Power steering whine

Well my power steering has been whining for awhile. Tried brake fluid, stop squeal fluid, Bar's that helps recondition it, and just tried transmission fluid. Nothing has worked. Transmission fluid makes it worse too. Any ideals? Or is it time to just change out the pump?

I have the same problem, I've had a buddy of mine say I needs a power steering flush but haven't gotten around to it. When I get it done and if it helps I'll let you know

You put brake fluid in your power steering? Hope not. That stuff is not compatable with rubber parts not designed for it. Just as if you put oil in the brake system. Hope you did not make more problems down the road.

Ive always heard you can put brake fluid in powersteering. Heard it is similar just alot thicker. It actually quietened it down more than the rest but still wasnt quiet.

You can add a cap full of brake fluid to slow a leak but I wouldn't fill the reservoir with it if it's wining you'll have to change the pump, but if you have a large leak you may pulling air in the system through the leak causing the wine

If it's bad just change it, there is no "miracle fluid" things wear out.

Probably will replace it. Have to get my first paycheck from my new job first. Should I use power steering fluid or transmission fluid? My Haynes repair manual says transmission fluid.

Already tried transmission fluid. On the way home from hunting last night the serpentine belt slipped off. Think the bearings went out in the power steering pump. Had my dad follow me to the repair shop today. Didnt get the belt back on so I didnt make it far before the heat gauge started going up. So I pulled it to the side of the road. Having it towed in tomorrow.

Well now with all the fluids you have tried, I would definatly flush out your power steering system. I would always go with what the mfgr recommends. If it calls for power steering fluid then thats what I would use. In days of old with strg boxes there was more latitude to get away with ATF. Now a days with rack and pinion steering I wouldn't risk it. You are risking what could cost you a lot of money to fix to save 10 bucks on fluid. Brake fluid has very little if any lubricating properties. It is designed to handle extreme heat and cold with out expanding or contracting. Not to lubricate moving metal parts.
