Topic: Unable to engage 4wd, lifter stuck in 2H

[Perfect Obsession]

Bonjour,
My original FJ-40 tcase shifter is stuck in 2H. I am unable to move it. I was thinking it was freeeeeezed by now it's spring time and still stuck.
Do you have any indication where I shall look?

The shift linkage gets dirty and grimy over time and eventually the linkage gets stuck.  Use a wire brush and some degreaser to clean all of the shifter parts and it should take care of it.  Oh yea dont forget to re-lube all the pivot points when your done.  Good luck!

I have seem many rusted 2wd-4wd shift shafts stuck in 2wd. Do you have direct linkage or vacume shift?
Begin by checking for rusted, frozen parts.

brakleen worked good to free up my tranny shifter, then i used wd 40 to lube it, give that a try

As soon as the temperature give me a break (about 30F & windy when sunny and 40F wet when raining), I will disassemble the mechanical linkages (no vacuum) and check for rust.

If it's only rusted, I will be really happy. I have the tcase exploded schema (not the exploded tcase schema) and I would check the ball-spring also. I am not convinced that's a rust problem since the linkage work easily the day before but the ball-spring ...

Thanks guys, I will comeback with solution.
