4510 front steering knuckle leaking

[BrianHat]

Bought this tractor from my FIL and the front steering knuckle was leaking before I bought it. He had it fixed by a reputable guy and now it’s leaking again with hardly any use from the fix. It seams this is a common problem on these tractors. My question is it leaking because of a different problem ( like bearing issue or pinion shaft distance, like a shoulder is wore). I think someone had a thread on a different model tractor I thought, but any help would be greatly appreciated. Thanks again

I have a NH TC45 that’s leaking a bit on one side. The manual says 80/90 GL5, but I wonder if corn head grease (00 flowable grease) would work.

This thing is it’s leaking a lot and I only used it like one time since it was fixed. It seems like it (bangs) into four wheel drive (front wheel assist). Not sure if this has something to do with it or if that is another problem?
