I'm not laughing! I've turned wrenches long enough to know that not everybody is going to know what I'm talking about especially when the average person probobly don't care.
Anyway, one thing we could do if you dare and I may get shot for saying this, is either drop all the oil or take the filter out and leave the cover off, fire up the engine long enough (no more than 30 or 40 sec.) to see if the noise is still there or goes away. (No noise, hyd problem)(noise, mechanical problem)in theory. MCV is Multiple Control Valve and operates the steering, brakes, and TA. Its that glob of plates and bolts and stuff on the left side below the battery. If you take this off get a couple 5 gal. pales to catch the oil. There are 7 bolts that stay in, 4 with brass washers that hold the pump and 3 short bolts, and they are in a small oval bolt pattern. After removing this you can check the gear on the pump (make sure its still tight to the pump shaft) and you can see the gear that drives the pump. If you can't see the faces of the teeth very good take the bottom cover off and you may get a better look. You will need new gaskets and o-rings for all this. Don't forget to put the spring and white plug back in if it hasn't been eliminated. Another place to look is the hitch pump. Located in front of the rear axle housing on the left side. This pump operates the hitch and auxillary remotes. Check the gears for the same stuff and when you put it back in put the cross over tube in the pump first and slide it straight in. You'll need a 15 gal. tub to catch the oil if you go this far. Hope this will help you out and if you find the problem let me know cause it does have my curiosity and don't worry about asking any questions.
