Power steering fluid?

[panteramatt]

My wife's 07 mountaineers steering is starting to make noises so I figured it's te for a flush. What's the procedure, how many quarts, and what type of fluid?

Just siphon the old fluid out, then replace with new fluid. Turn the steering wheel from lock to lock to bleed the air out of the system. You could install an inline filter on the return line.

That won't get all the fluid out. Also is there a good synthetic fluid I should use

IIRC, reservoir inlet hose size is 3/8". Use a cheap turkey baster to remove old reservoir fluid. Rubber vacuum cap to plug reservoir.

One quart of Mercon V is usually adequate until fluid runs clean. I did it alone without the engine running. Purging wasn't necessary.

The only fluid I use for power steering (except on vehicle that take special stuff, like our Honda) is Mobile 1 Multi Vehicle Synthetic ATF. It works well and keeps the Ford power steering pumps from sounding like a Ford power steering pump (older pumps, they got better in the later years)...
