About a month ago I got in my car to the power steering being hard so I added some fluid. I had no problems for about 2 weeks when it happened again. I now have to refill the resivuar every 2-3 days. I have not seen any leaks under the car and I have been using fluid with 'stop-leak'. Anyone had a similar situation? Any ideas where it may be since I dont see a leak. BTW, I had my C-V joints replaced about 5-6 weeks ago if it matters.
