    If your power steering pump is making noises or leaking, get it fixed ASAP or you will likely be replacing your alternator too. The alternator is located right below the P/S pump and if fluid drips into it it will short out the alternator, this has been occured many times.

    Also, if you get a puff of white smoke in the morning it may be a bad speed sensitive steering solenoid, which screws into the power steering pump and has a vacuum line running to it. Either order and replace the solenoid/switch (about $100 online) or it can be plugged with no loss of function in the steering also. *DO THIS AT YOUR OWN RISK*, I just plugged mine after others online reported it would work OK and it seems to steer fine.
