4 lo won't disengage

[JBecker]

cool.

now for a manufacturer to step up and start producing such a thing.

Yeah, everything I've read seems it's a guy who made it himself. I'm reading up on FJ transfer case swaps and converting the front to manual locking hubs.

Just a little update to anyone interested. Saturday we were able to disengage 4LO from my T4R. As suspected the actuator was frozen solid but we were able to get some silicone spray in there and connect it to a 12v power supply and that was enough to spin it free.

Once reassembled we took it down the road and had to play with the switch but once we did it popped right out and has been fine since.

Now to get to that actuator we had to take apart the gears for the center diff lock and I haven't been able to find anything for the correct timing on that. If anyone has a link to a thread for that timing or just happens to know it, it would be much appreciated.

I have an 05 V8 4Runner the CDL was stuck so we replaced the t case with a used one and now the it's stuck in 4lo. Any suggestions on what to try?

Starting with the simple solution: No offense intended, but are you switching out of 4 lo the right way? Truck stopped, in neutral? D-N, shift out of 4 lo- back to D

Second, if that doesn't help. Tap the actuator with a brick or a big hammer to see if you can get it to unfreeze if it's stuck.

Thanks!!
