My apologies if this breaks any rules. They are currently showing an air locker install on a Dana44 on Extreme 4x4 (Horsepower TV). I know Eric and a few others were looking to replace a differential, and thought this is a good lesson...even though it is on an International Scout....and you're probably not installing an air locker. Most of it applies to all differentials. Here's the link.

Oh yeah, it also made me remember why you want to take it to someone really qualified.

 

I didn't watch the video but I watch extreme4x4 all the time so I've probably seen it anyways. Gears take a lot of work if you don't get the backlash setup right you'll get early gear wear not to mention they'll be really noisy. For a 2wd truck it wouldn't be that big of a deal to tackle but for the IFS 4x4 guys, IMO it'd be a pain with that front axle and little room to work. If you watch extreme 4x4, most of the axles aren't under a body before they start the work. I've never worked on an IFS 4x4 but if I swapped gears myself I would think you'd need to drop that front axle out and lay it on a bench. If you've tried changing the gear oil you may already understand how tight for space you are.

 

After watching that I'm definitely going to have my gears installed by someone good when I change them.

 

Yea, I watched that on TV. What a pain in the ***. So many little things to it.
