It's been suggested that I have air in the lines of my power steering. Would you be kind enough to explain to me how to bleed them?
Do you
have the same problem?

HYDRAULIC SYSTEM BLEEDING
Fill pump reservoir. Start engine. Operate steering for 2 minutes, or until power steering fluid reaches operating temperature. Stop engine. Recheck fluid level. Add fluid as necessary. Repeat procedure until fluid level stabilizes.
Raise and support vehicle so front wheels are off ground. Start engine. Turn steering wheel from stop to stop several times. Avoid holding wheel against stops in full left or right position. Fluid level should remain visible.
Return wheels to center position. Operate engine for 2-3 minutes. Lower and road test vehicle. Recheck fluid level. Fluid containing air will have a milky appearance. If air is still present in system, repeat preceding steps. All air should be eliminated to obtain normal steering.
NOTE:If abnormal noise or foamy/milky appearance of fluid persists, air may be trapped in power steering system. Using Rotunda Vacuum Tester (021-00014) and the following procedure to eliminate this condition.

Carefully remove dipstick. Check and fill reservoir to COLD mark. Disconnect and ground ignition coil lead. Raise front wheels off ground.
Crank engine 30 seconds while turning steering wheel. DO NOT hold wheel on stops. Add fluid if necessary. Attach coil lead. Install vacuum tester onto reservoir.

NOTE:DO NOT use engine as vacuum source to purge air from power steering system.

Start engine. With engine idling, apply 20-25 in. Hg vacuum to reservoir. As air is purged from system, vacuum and fluid level will decrease.
Maintain specified vacuum for about 3 minutes. Release vacuum. Check fluid level. Fill as necessary. Install dipstick. Start engine.
Turn steering wheel from stop to stop while checking for leaks. If air is still present in system, repeat procedure until all air is removed. Lower vehicle. Road test vehicle.

Turn the steering wheel all the way to left and hold for thirty seconds then to the right and do same. Repeat this five times. Make sure fluid level is full prior to starting and finishing.

There is a tool that ford makes, that is used to suck out air from the reservior as it is running. There is a particular procedure, I can look into it if someone doesn't help you first. It can be a p-i-t-a, but will work.
