They want to replace pump and lines ($1,000) - just started acting up - almost out of fluid after recent 90K tune up! I'm NOT happy
Power steering leaks and must be on the return side as filling with fluid will last a few days before sound starts again. Need to know how to find free info on how to repair this.

I lost power steering due to another leak in hose..had fixed several time but it has happened once again. Onetime clap came off of hose, another small leak in hose and now who knows. Iput fluid in but still no power steering nor see it leaking out. Will have to pay about $100.00 to have loked at and see what is wrong this time. I have more problems with the p[ower steering in this truck than any other problems in any car I ever owned,.

Power Steering leaging but very hard to find, i am overseas right now but the maintenance shop can't seem to find the leak for my wife.
Does the pump have to come off to replace the HP Line.
Terrible noise while turning. Poor turning radius. Adding fluid tonight while waiting for appointment to get car checked out.
