Hey guys and gals. I have been reading through a ton of posts on here about these hydraulic cylinders leaking. My Left Main Cylinder is leaking at the bottom port where the hydraulic line attaches. I had expected it to be at the end of the cylinder, but it is just the hose port that is leaking.

Could this be a DIY repair or do I need to send it in to Top Hydraulics? Perhaps this connection just needs to be cleaned and re-seated??
