Went down this road a year ago with my 372. Going to disagree with previous comment, absolutely buy the seal from Vermeer. This is an extremely heavy duty seal, made for the application. Go to a bearing supply house you’ll get a “will fit”. Also, replace all bolts in the bolt ring with Vermeer bolts, they come coated with a Loc Tight. Getting wheel off is easy, next is the large nut that holds the flange on. It took my 3/4 gun to get it loose. The flange takes a pretty heavy duty 3 jaw puller to remove. With a few blows from a sledge. I had to fab a seal driver just for this, since the seal was 60$ did not want to eff it up. The only trick on reassembly is I torqued large nut then smacked flange with a large brass hammer to reset, torqued again, repeat. This is not a hard fix, just requires some tooling.
