Cat 287B Hydraulic issue while driving forward and turning right

Hello, I recently bought a used 2004 287B and have noticed a few issues with it. The one main issue is that sometimes when driving ahead at full speed then trying to turn slightly to the right, the skid steer slows down and the back-up alarm will come on, then if I let go of the joysitck and drive forward, reverse or turn right or left there are no issues, its only when driving ahead and trying to turn slightly to the right....any ideas?? The other issue I had but cant replicate anymore is that I was able to raise the work tool, and tilt both ways, but sometimes when lowering it, the work tool would come down a bit then i could feel a click in the joystick and then no functions on the right joystick would work until i drove the skid steer ahead or back, which would then let me use some functions on the work tool, and sometimes when lowering the work tool it would drop fast then slow down. I did notice these issues right after giving the unit a good washing so maybe some moisture got into an connection? Might explain why it is not doing it anymore?? Any help would be greatly appreciated! Thanks!
