I have a 2003 Cadillac leaking power steering fluid from underneath on the right side.refilling fluid about every 10 days. Help

Check the power steering fluid and make sure it is at the correct level. Check for leaks underneath the vehicle. Does the vehicle make a groaning noise when the wheels are being turned? If so, there is air in the system. Likely causes are a fluid leak, bad pump, or bad rack and pinion.

i would think that it has splash shields under the car as well.
so i would drive it up on ramps remove the bolts holding the shields in place, remove the shields, wash the engine, refill
the steering fluid start the car and look for the leak under the car.
Good luck and don't forget your face shield you Will need it!

You should be leaking something, which would mean you should also be low on a fluid after driving.
Are any of the fluid levels low now ?
You may have to clean off the engine to find the source.

Place a sheet of white paper underneath in the proximity of pump and rack. or anything that will show the leak. If you have a set of ramps that would help as well. clean underneath and roll up on ramps check for leaks while running. Or if you have jack stands , puy on that and have someone turn lock to lock while you look for any leaks. I wouldnt just start throwing parts at it

CHECK POWER STEERING HIGH PRESSURE HOSE.SOUND LIKE ITS LEAKING POWER STEERING FLUID.

SR you just found the problem a leak in the power steering system, check the floor were you park the car every day, there steering fluid by the driver side the problem is the steering rack, there is fluid by the engine passenger side, pressure line, banjo fitting, return line, and also steering rack, the best thing to do is clean the oily area, refill reservoir drive it and check for a fresh leak.

Might just be a loose connection on the power steering hoses. You'll need to get under (BE CAREFUL) your car or get it up on a car hoist. You or a mechanic, should be able to trace where the leak is and either tighten the connections or replace the hose. Cold weather brings on leaks ! !
I don't think the brake vibration has anything to do with it. Brake vibration usually means the brake rotors are warping. Common problem. Have you have your brakes checked lately? Might be time for new pads and rotors.
Good Luck

this is tranny fluid. ive had the problem myself. its most likely a hose that goes from the tranny to the tranny cooler that is located at the front of the car and is sometimes part of your radiator. get this fixed ASAP

patch it with a high pressure hose and two clamps

if the power steering fluid is full and belts ok but, it happened suddenly, provably the power steering pump shaft was broken.
