My 94 has been diagnosed with a ailing rear transfer case seal. While having that replaced, what else should I consider doing in an effort to get economy of scale on the labor portion of the bill? I'll have them replace the speed sensor o-ring - which also may be leaking.
All that needs to happen to replace the rear TC seal is to drop the driveshaft on the front end of the rear shaft, pop out the old seal and tap in the new one. It's a 15 minute deal.
The only other possibility would be if you need to replace a U-Joint.

Replace the transmission output seal and the transfer case input seal since the transfer case will be removed and disassembled.
Both seals are the same part #.

I'm about to do this. I luckily bought two seals in case I mess up one of them. If I get the first one in (rear output) without difficulty or harming the seal, is there any decent write ups for the input seal? Any need to replace any bearings in there?
You don’t just pull the seal. You have to split the case and disassemble the back half to get to the seal. Is it hard? No. T-case can stay in the truck and attached to the transmission.
Strongly recommend you replace the output bearing. It's all going to be disassembled anyway since you have to remove the rear section, and then use thin c-clip pliers to disassemble the output. Be extremely careful with the oil pump shims when it goes back together.
@BILT4ME - it isn't like a normal transfer case with a separate flange. The flange is actually part of the output shaft. Not sure why Toyota did things that way since it makes it significantly harder to work on.
