Tractor Repair: 2002 JD 5105 MFD, front end loader, hydraulic hose

Question
I have two questions:

1) One or both of the hydraulic power steering lines are leaking where the fitting meets the hydraulic hose, upon replacement of the hoses do I need to bleed the hydraulic system?

2) On the front end loader the timing is off between the two cylinders that drive bucket roll, is there anyway to resync both cylinders?

Hope this makes sense.

Answer
Well you are in luck this happens to be my area of expertise.
  Question #1 no you do not have to bleed the hydraulic's when you change the lines. After you change the lines or fittings just start the tractor and turn the steering wheel to both right and left stops until the pump stops making noise. It should not take to long.
  Question #2  What ever cylinder is slower to respond has a problem. Either the piston came off the rod or the packing is bad. You can take the cylinder off the loader and take to a dealership to have it rebuilt. Not too expensive either. To be on the safe side take both cylinders off and have them both repacked, cause whatever happened, the other one is not to far off.

By the way it makes total sense.
