I cannot seem to be able to get all the air out of my power steering. I've followed a couple different write ups and I still have air afterwards. Any good tips for this or what has worked for you? Thanks

I raise tires off the ground and just turn the wheels back and forth. worked so far.

Gee oh Dee

^^This.

I've done that. It might be the obvious and something is letting air in. I do not have any leaks but I'm gonna pull it off and make sure the res is sealed.

What is it doing that makes you think air is still in the system?

I broke the res awhile back and after replacing that it started taking about 5 min of warming up before the wheel will turn with ease. Usually If I go back and forth it'll loosen up faster. Ive just never had this problem until I replaced the reservoir.

Lucas power steering does wonders. Try it.

Are you sure that you do not have a power steering fluid leak somewhere? The system should not "leak air" into it, regardless of how long it sits, whether overnight or a week or whatever. The only way air can leak in is if PSF leaks out. Recheck all the PS hoses and connections and be sure that the hoses are in pretty-near-to-new condition. If they are old, cracked, metal parts corroded, threads damaged, etc. just replace them. It's easier than dealing with trying to chase down some microscopic leak.

The other thing is that the power steering pump itself could be bad.

According to my manual, this is the bleed procedure:

1.) Fill the power steering pump with fluid. Operate the engine until it reaches "normal operating temperature," then stop the engine.

2.) Turn the wheels to the full left and full right position to circulate the fluid. Add fluid to the reservoir to maintain full level. Start the engine. Check the fluid level and add if necessary.

3.) Purge the system of air by turning the wheels from side to side WITHOUT GOING TO THE FULL LEFT OR FULL RIGHT POSITION.

4.) Return the wheels to "straight ahead" position and operate the engine for 2-3 minutes, then stop the engine. Add fluid if necessary. Road test the vehicle.
