:? I changed the hydraulic oil in it and replaced a couple hoses going to the bucket and now it leaks down as i am driving.Any ideas of why?Just the bucket,not the arms. :?:

Typical cause would be the piston seal in one of the cylinders has started leaking.

Since they are plumbed in parallel, if either piston seal leaks, both cylinders will "settle".

If the loader circuits are connected to the tractor with quick couplers, you can "curl" the bucket up, then unplug the two hoses and see if it "holds", to rule out the small possibility that something is wrong with the valve on the tractor.

Could be some air still trapped if your lucky.

There are no external leaks.I have checked that over and over.
