The bearings, I never had trouble with. I didn't run the 35 Hawgs on the street very long. About a month of street driving. On the street I run stock rims with 31x10.5s. For a B2 with it's tiny wheelbase, a 31 is enough tire to do almost anything.
The thing about wheel bearings is, they like to be loose, but close. When you preset them, you have to run the wheel back and forth while torquing them to 35 ft# or whatever. Then, you let them all the way loose and snug them to 25 or something INCH-Pounds. Just to take up clearance. It's important. The locknut goes to 150, though I know some people tun it tighter. I think if you need to run it tighter, you have't spent enough time getting the extra grease out. Huge offset rims, though, I would listen to the poeple that run them regularly and haven't had failures.
Anything you do with anything--the trick is to find the people that like it and do what they do. If you find the people that don't like it, they did it wrong. You don't find out what to do with a D35 by looking at D60 people.
You aren't going to put 37s on my truck and bust it, know what I mean? My truck is old, polished and I've been there with it. I have a pile of axles that broke, and I studied why. My truck will run 90mph on the highway, carry and plow with a 500# plow, run about any trail you want to run--easily, and get you home again. It's perfect. It's the thing you go get when everything else fails. It took a long time to get here, but it doesn't have Dana 60s and whatever. But for ten years it's plowed my snow, skidded logs, hauled firewood up and down seriously steep Brown County hills, pulled people out after heavy snowstorms, pulled sleds of screaming kids up and down the field, and even gone on a few 4-wheeling excursions. Oh, and it was my daily driver.
You massage your truck and make it what you want it to be. If it breaks, figure out why and fix it. Don't just slap on bigger axles.
I have enough money to do whatever I want to. In ten years with this thing, nothing has happened that I couldn't figure out. It's a hog.
For mowing grass, I have a Toro Groundsmaster--not a Yardman. For general gruntwork and occasioanl fun, a B2 with a 4.0 and properly massaged D35/8.8 meets the bill. It's a professional grade setup, if you figure it out.
