The key to a well done front axle job is not just replacing the parts, gaskets, seals etc.
It's all about cleaning all of the most important components. Studs, housing, calipers, slide pins, bearings, free wheel hubs etc.
The key is cleanliness. Just like Rice's pictures of the xfer above: Everything is clean-- bolts, hardware, housings-- everything. That's where the time intensive aspect comes in with any of these reasonably normal maintenance jobs.
If you neglect to clean things or replace damaged components you'll be going back in and doing everything all over again.
For example, inspecting wheel bearings carefully is paramount.
On an initial inspection, the outer wheel bearing looked great. Upon closer inspection, I found this degradation:
That bearing is toast.
New one should be installed.
Personally things like thrust washers should be replaced since they interact with moving parts (outer wheel bearing).
All studs should be inspected for trueness.
I pull wheel studs out as well just to make sure they haven't been cross threaded and that the serrations on the body are in good shape.
Remember, Toyota designed these machines to act like "tools": IE: They have functional life spans for all components. Just like hours on a Kubota or a 100 ton Trumpf press-- land Cruisers are machines that want interaction, need interaction from the user.
Just my philosophy at least. There are varying levels of this thought stream though.
