What causes a double action cylinder with no leaks to drift? Every other cylinder on the system does not drift.

The fluid is bypassing the piston seals internally. It sounds like it need to be rebuilt.

Yep, internal bypassing is the usual answer 99% of the time. The other 1% is a worn control spool.

It is leaking, but not where you can see it.

You may also have a seal that is nicked that is causing this. Possibly in the cylinder or in the loader valve. It should be pretty easy to fix.

Thanks. If you can't see something leaking, it doesn't mean it's not leaking. On removing it I noticed it is rebuildable, so I guess the best thing to do is take it down to the cylinder rebuild shop.
