lower link pin leak

Anyway, I have a project coming up in a couple weeks and am in need of some advice. Both sides lower links leak badly and it's time to do something about it. I have already purchased new arms because the ball sockets are very badly wobbled out. Also, I fear that the pins themselves may be worn, but because they both spin freely in their current condition, I can't get the arm off to check. My thought is that maybe I should buy new pins to have on hand. So my questions are:

Do these pins actually wear out, or are the odds with me that they are probably in good condition?

If I do need replacements, are all pins on the N's the same? (The ones that I have found online usually confirm that they fit an 8N, but very few references to the 2N?

Finally, does the trumpet require a gasket, or is a sealent sufficient? I'm confident it would seal just fine, but my concern would be tolerances.

I appreciate any feedback, and look forward to being a more active member of this forum!

You will have to pull the left hand axle housing and the differential which will just about fall out after the left side is removed. Just pull it off the right axle stub. It's heavy so don't loose a finger in the process.

I personally would use just silicone gasket maker for the trumpet housing. There is a slight issue with the axle preload but with an old tractor that no new bearing have been installed in the small amount of clearance taken out will not be noticable. Probably even be better since it will tend to take up for normal wear of the bearings.
