So I have a 69 Fastback with a Mustang II front suspension. Everything seems to work nicely but when turn the wheel all the way left or right the pump squeals like a pig! Is there some sort adjustment I am missing? (the PS pump is a saginaw type)
Squeal when holding the steering against the stops is normal. You are forcing the pump to hold the steering arms against the stops at 800-1000 p.s.i. and the drive belt can't take the strain. Ease up. It's not like all that force is helping you turn.
Thanks... I only have this problem when I am moving in and out of the garage and such. When I get the squeal I also get PS fluid leaking. Isn't there some sort of pressure relief valve that should shunt off the pressure if it gets too high?
Yeah, but that's inside the pump. When you jam the steering against the stops, the power cylinder spikes to full pressure. Just back off zillionth of an inch when you hit the stop, and your steering parts will last a lot longer.
