I have a 3650 and this past while I’ve notice a bit of a knocking noise from the front hydraulic pump and it gradually got worse then the last day I used it it was screeching nearly sounding like a fan belt slipping and the steering started to misbehave as if there was filings in the back end, so I screwed the filter bowl off and there’s filings in the bowl would they be coming from the front pump, any help advice would be appreciated, thanks in advance.
