If you're very mechanically inclined, you can do it. If not, it's probably best left to pros. I've been wrenching my whole life and just did my first axle earlier this year, took me 2.5 months to get it right and 2 sets of gears (granted, life got in the way. It was probably a solid 5 weeks of working on it after work and weekends though). My best advice if you're gonna tackle it, buy quality parts. Granted if you're just doing bearings and seals, that's a whole lot easier than doing a gear change like I did. Go slowly on disassembly, make notes of everything, keep track of where your shims were and it *should* go back together pretty easily. You still need to run a pattern though to make sure it was right before it started having issues, you may have to adjust some shims. Get 2 sets of bearings and make a set of "setup" bearings for this. There's plenty of YouTube videos for doing these 10-bolts
