Keep us informed. If you have more issues and it turns out to be the pump, I posted detailed instructions when I upgraded mine. Pretty simple to do but hopefully you have it going.

Before you spend a lot of money, if you have intermittent problems, could be air in the suction line. There is a rubber connector (6" long) in the suction line from the back of the tractor to the pump. We have seen this rubber connector get hard and crack over time, especially at the 2 hose clamps. It doesn't have to leak to be able to suck air and cavitate the pump. Just a simple check before spending a lot of time and money. We have seen this on several older LK3054 Tractor.

Hope this helps.

Could this be a relief valve acting up?

Hopefully the filter was the issue!

I agree that rubber connector can be a problem, I just changed mine last week that I ordered from Michigan Iorn.

I never had a issue with the pressure relief but it certainly could be a problem. But if the problem still exists, I would look very closely at that pump.

Could this cause intermittent steering failure? Happens once in a while especially when I'm bush-hogging, steering stops responding. Turning the wheel back & forth a couple times "fixes" it. Only affects steering, not FEL.

Where is this hose, is it easily accessible?

Yes, this could be a cause of steering loss. Could be other issues as discussed here, but air in the system can be a cause.

The rubber connector is near the bell housing behind the pump. Follow the suction line from the back of the tractor along the right side, you'll find the connector near the bell housing.

Hope this helps.
