Hi

I have a b7100d that has recently started to squeal when trying to lift a trailer on the hose but seems to be fine when on the 3 point hitch.

Thought it could be a the hose connection that has been previously damaged so after getting that replaced still same issue. So I am guessing it not the pump due to the linkage working and must be the flip over switch for the hydraulics (from three point to hose ) has a seal or o ring blown.

I have read other threads that it could be a relief value that's blows.

Anybody got any better ideas before I starting taking things apart and looking for dodgy seal and o rings?
