Hey all,
Im currently doing an conversion on my pov pack 2004 modle HZJ 105 series land cruiser chucking in a 1HDT engine, gearbox an transfer case.
Seeing if anyone else has done the same conversion. Im wanting to convert the transfer to part time 4wd.
Is anyone able to help with the conversion from full time 4wd to part time?
Trying to research how to go about it but not having much luck on information.
Car runs goes all the rest just driving around woth no 4wd at the moment but wanting to convert her soon to hit the tracks.
Any help would be much appreciated.
Thanks in advance 🤟

We need more information:

1. What transfer case do you have on your HZJ105?

2. What transfer case do you have on your 1HD driveline?

You should be able to get everything you need from a wrecker in your part of the world either from a wrecker yard or from a Terrain Tamer location.

Easiest most cost effective way would be to drop the 1HD in front of the R151 and then convert the transfer case you have to part time using Terrain Tamer parts and manual hubs.

That said, I’m not sure the R series transmission will have much good luck behind a 1HD.
