After I lifted the '84 and replaced the push/pull steering with a Hi-Steer kit I also needed an IFS steering box. I bought one from richpblaze on RME and it has worked flawlessly up until late. The input shaft seal has been leaking since the U4WDA winter convention, tired of the ATF puddling in my driveway I located a seal through NAPA.
This is the lazy man's fix, it does not require removing the box from the Truck, nor does it involve a full tear down of the box for the typical re-build.
Here are the tools I used, pretty basic stuff:
Seal NAPA part number--7007--this was a special order seal for a Cressida, it was $5.00.
12MM Wrench for top bolt, a socket could be used.
14MM Socket with long extension for lower bolt
Flatblade screwdriver
Hammer
Vaseline/grease
Quart of ATF
Rags
Solvent--I use Isopropal Alcohol for most parts that are not hot. It's cheap and easy to find.
1st
Remove the steering shaft from the box and remove the bolt on the upper steering shaft that connects to the firewall/steering wheel.
2nd
Using a chisel, regular screwdriver or prybar locate the raised tang on the edge of the input cover. Strike this with a hammer to loosen it. A bunch of ATF awaits you underneath.
3rd
Remove the input shaft cover and press out the old,hard seal with your thumbs.
Clean the seal housing thoroughly and press in the new seal after lubing it with Vaseline. I like vaseline because it's cheap, not very messy and mixes well with other oils.
