Power Steering pump appears to be leaking but is full????

2000 Buick Lesabre Custom, high miles. Fluid on hoses below power steering pump reservoir and some on ground. Reservior appears full when checked. Fluid is dark. Whining while driving, seems to go away once shifts into fourth gear (automatic). Starting to feel occasional vibration or shudder for one to two seconds at a time while driving at 20+ mph. Is it the power steering pump?

    power steering reservoir is full. on this engine it is a direct drive power steering unit (no serpentine belt on it), it must run right off the top camshaft of the engine? Im getting a crunchy/grinding feel when turning extreme left. You can feel it thru steering wheel. There are no obvious fluid leaks anywhere. Would this be a rack and pinion issue?

    The power steering starts working again a short time later.

Just guessing. Could it be a warped brake disk? That would cause vibration. And vibration in steering might conceivably cause splashing out the power steering reservoir. You would know if the disk were warped by a shudder when you brake at hight speeds.

2000 Buick LeSabre power steering dip stick. Where is it?
The power steering fluid level is indicated by marks on a fluid level indicator. The fluid level indicator is located on the fluid reservoir cap. Inspect the fluid level when the engine compartment is cool. Ensure that the fluid level is at the FULL COLD mark. When the engine compartment is hot, ensure that the fluid level is at the HOT mark.

Located on back side of engine below the alternator

How could you tell if the power stearing pump is going out . It leaks p/s flu , could it also be that the hose is damaged?
If the power steering pump is on the way out, usually the steering will become jerky when turning. It may also develop a whine noise in the engine compartment. The fluid will appear foamy as it aerates and mixes with the fluid. Good news power steering pumps rarely fail, unless run out of fluid. It is more likely the pump front pulley seal is leaking (you should see a tract of fluid along the padding in the hood liner). The other possibility is a hose, usually the high pressure hose leaking at a compression fitting (where the rubber meets the steel ends). Check the fluid level and condition. Check the hood liner for traces of leaks, check underneath for drips, or extremely wet areas along the 2 hoses.

After I replaced the power steering pump and reservoir on my 2002 Jeep, I still get air in the system. Where could it be coming from?
Your problem could be a pressure side hose that has a rupture that only leaks in extreme conditions. Inspect to replace with new to repair problem. First make sure you have removed the pump caps off of the hose fittings. If ok, it appears you may have a stuck valve in the rack assembly. Replacing the rack should solve your problem. ------- The new pump should be self-bleeding by turning the wheels left and right. Let sit over night to release air bubbles, recheck fluid level.------ Check the tension of the drive belts on the pump, as they may be loose. The power steering pump and reservoir is located on the front of the engine driven by one of the fan belts. There is a removable cap on the top with a dipstick attached. With the engine off, fill this up to the full mark with power steering fluid. Replace the cap, start the engine and check for leaks. On the back of the pump are two hoses either one could be leaking. REPAIR PROCEDURE:
1. Wipe the power steering cap and area free of dirt. Remove the power steering cap.

2. Use a siphon pump to remove as much fluid as possible from the power steering fluid reservoir.

3. With a helper in the vehicle, raise the vehicle on an appropriate hoist.

WARNING :POWER STEERING FLUID, ENGINE PARTS, AND THE EXHAUST SYSTEM MAY BE EXTREMELY HOT IF THE ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES. DO NOT ALLOW HOSES OR POWER STEERING FLUID TO TOUCH HOT EXHAUST MANI FOLD OR CATALYST. 4. Locate the power steering cooler attached to the crossmember support plate. Slide back the clamp and disconnect one of the two power steering return hoses at the power steering oil cooler and drain fluid in an appropriate container.
5. Have the helper turn the steering wheel back and forth quickly several times to force as much fluid as possible from the steering gear.
 6. Reconnect the hose at the oil cooler using the original clamp.
7. Lower vehicle so the vehicle tires are not contacting the ground. 9. For proper fluid fill and bleeding air from the power steering system:

a. Fill the power steering reservoir to the top of the fill range using Mopar power steering fluid (ATF+4) p/n 05013458AA.

b. With the engine OFF and the vehicles tires off the ground, slowly turn the steering wheel back and forth (lock to lock) slowly 20 times to force fluid into the steering gear.

c. Fill the power steering reservoir to the top of the fill range.

d. Start engine and let run for a few seconds, then turn oft engine.

e. Check fluid level and add if necessary.

f. Start engine, and slowly turn the steering wheel lightly contacting the left and right stops.

g. Stop the engine and check fluid level. Add fluid if necessary.

h. Lower vehicle, start engine and slowly turn steering wheel lock-to-lock.

I. Stop engine and check fluid level. Add fluid if necessary.

j. If fluid is extremely foamy, allow vehicle to stabilize a few minutes, then repeat steps "i" and "j" until the fluid level remains constant after running the engine and turning the steering wheel from lock to lock.

10. Inform the vehicle owner/operator that a steering vibration may be noted for a few hundred miles until the air is completely removed from the steering system. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

check to see if you have power steering fluid. if your low fill it up. (most cases thats all it is) check around for any leaks or parts to the power steering unit for and damage (hoses, pump, rer, rack and pinion, any seals or such. you might have a leak somewhere. when your looking for leaks fill the res up with power steering fluid. turn the car on. and have someone turn the wheel so get the fluid to build up pressure in the system.

Power steering rack leaking
If it's coming from the rack, check the rubber boots from the rack to the inner tie rods, and if they are soaked with fluid, you will need a new rack, or keep adding fluid to the pump as needed.
Hope this helps!
