i removed the ps pump and vacuume pump as i had to replace motor and now the ps and brakes don't wanna work right the ps pump seems to hum to me now could this be caused by air in the lines? if so how do i bleed the system just crack a line?

 

Fill up the ps pump reservoir. Lift the front end off the ground(jack stands work fine). Turn the wheel left full lock, right full lock 20 times each way. Keep checking the fluid level.

Start truck, and test, while still with frontend off the ground. If it still growls, do the procedure again.

 

thanks i will give that a shot today

 

well i finally got around to trying this today and it worked like a charm. Thanks Fred!
