OTRAMM's video is great, helped me immensely.
Trail Tailor sells a reproduction version of the tool if you're looking for one.
Things you might need/require for this job that you might not be able to find locally besides the obvious seal/bearing/gasket kit.....
Dykem Blue or spray on Layout Dye for use on the SST (can be found at graingers if not avail from local auto parts store)
You'll need a larger than normal pair of calipers to capture knuckle measurements, commonly avail sets only go up to 6" and you will need to capture measurements in excess of that, in the range of 6.5 ish inches. (can be found at graingers if not avail from local auto parts store)
If you have electric hubs you may want to order the required 3x T20 screws per side that secure the e-hub face to the hub just in case.....my HZJ77 called for p/n 90149-50055 and whomever you purchase seal/gasket/bearing service kit from should have what you need for your year/model LC.....plan for worst/hope for best.
Servicing the e-hubs requires Toyota 08887-02007 "Body Grease W" or equivalent which is supposed to be Molycote 44 light I believe.....the stuff is pricey either way but the factory grease can be ordered from your local dealership still.
