Has anybody tried the Posi Lock cable actuator I have seen advertised? It replaces the funky thermal actuator that came on my 88 k1500? I am thinking it might be the closest thing to manual locking hubs?

Many people have posted about using them usually whenever a question about replacing the front axle actuator shows up. It would allow 2 wheel drive in low range

I love mine. It's great. It's about like manual hubs except you can lock it in without getting out. Once I get my pictures moved from photo bucket, I can post a picture of the button inside the ash tray. I don't smoke and that giant red button is an eye sore.

I like mine. Does what it is supposed to do with no fuss. It does add the option of using your 4 wheel low gear in two wheel drive mode.

How does that work? What happens to the floor shifter for 4 wheel engagement?

The floor shifter still operates the transfer case. It just gets rid of the problematic thermal or electric actuator and replace it with a cable actuator.

Think of it like manual locking hubs. With the actuator disengaged and the transfer case in 4wd, the drive shaft will be turning, but the power won't make it to the wheels just like having your hubs unlocked. If you put the shifter in 4wd low with the actuator disengaged, it will essentially be in 2wd low range which is excellent for backing a trailer in a tight spot. The indicator light on the floor will be on any time the actuator is engaged regardless of where the shifter is.
