Power steering pump-To bleed or not to bleed
Hi all,
I just rebuilt my vacuum pump and replaced the power steering pump. My problem is a medium frequency vibration , especially in the morning after first start. Should I have bled the power steering pump, and what is the procedure?

Here's from the '91 manual
Pump - Initial Operation.
1) Fill reservoir. Operate the engine until the power steering fluid reaches normal operating temp, then stop engine.
2) Turn the wheels to a full left turn position. Add steering fluid until the res. is full.
3) Start the engine. Operate it at a high idle and then observe the fluid level on the dipstick. Add fluid if Necessary.
4) Purge the system of air by turning the wheels from side to side without contacting the stops. Fluid with air in it will have a milky color. Maintain reservoir full of fluid.
5) Return the wheels to the straight ahead position. Operate the engine for an additional 2 to 3 minutes, then stop the engine.
6) Road test the vehicle to ensure that the steering system functions normally and is free of noise.
7) observe fluid level. Add fluid as necessary.
