I feel like i’m the only one who wants to keep their 80 full time. I love the way it drives on and off road. Maybe if i had a bunch of driveline slop i would feel differently. To me Mr. T designed it this way for a reason and i see very few benefits if any from going part time.

[@OzTrax4X4]

The DX model was actually part time from the factory. While full-time is great, the benefits I find of being part-time far outweigh it. 1. Less wear and tear as you're not driving the front axle at all. 2. If you're being silly and destroy your front driveline, you can just unlock the hubs and let it free wheel and have a chance of making it out in rear wheel drive. 3. Fuel economy and torque is improved as less components are being driven. There are probably more but that's all I have off the top of my head for now.

Thanks mate. Next two videos will be good to watch I think.

Is Sock sporting a new beard?!?!? Definitely need to do this to my 80. Anything to help the fuel mileage is a plus. Good vid Mic.

Nah, no new beard there, just longer. 😆

Instead of a truck I have a sports car that’s full time 4WD (AWD) and wanting to convert it to part time AWD (4WD) to get the feel of RWD as well The sports car I have is a ‘96 celica gt4, how may I go about this? Is it on par with the process in this vid, or totally different…

[@OzTrax4X4]

Unfortunately, AWD is a very different beast to 4WD. To go rear wheel drive, you'd need to have a locking centre differential and no drive to the front wheels, which would be in the way of removing the CV shafts to accomplish that. Being that they are primarily front wheel drive biased, you'd probably have to do a lot more research. Maybe TOM's back in the day had a way to do it. 🤔

[@khilanparmar2402]

I got free wheeling hubs at front diff on my 80 series, does that mean or force me to change the spool in transfer case to part time kit aswel?

[@OzTrax4X4]

That all depends if it is operating correctly. You will need to have a centre diff lock button. If you can drive around with them disengaged and the centre diff lock not engaged then it would have the spool fitted. This really only applies to factory full-time 4WD vehicles. If it's factory part time, then it should work as per normal.

[@user-xb1tl4lw5d]

I saw some converting video just removing small two gears btween companion flanged and welding the gear for rear flange . This for 100 series land crusier.

[@OzTrax4X4]

That is effectively welding the centre differential which I wouldn't recommend when it's inside your transfer case, especially if it decides to explode and send bits of welding metal through your gear set and centre differential. That there is an expensive accident waiting to happen if you do that. My advice is to do it once and do it properly. 😎👌

[@user-xb1tl4lw5d]

@@OzTrax4X4 Thanks alot for your advise.

[@OzTrax4X4]

No problem mate. Using the correct parts will ensure you won't have an expensive repair bill 😎👍

[@HDBujutsu1775]

Sweet

[@narcosplays7948]

It wouldn't work if you only replace the manual hubs ?.. mine it's a 94 full time.

[@OzTrax4X4]

Unfortunately not, as if you unlocked the manual hubs, drive to the cruiser would take the path of least resistance, which means you'd get no drive at all. By fitting the spool to the transfer case, it locks the centre diff to the rear wheels when not engaged in 4WD. Your centre diff button then becomes your 4WD button. I hope that explains it a bit better.

[@flunic6869]

You saying that you can convert the 94 into a button 4wd switch

[@OzTrax4X4]

If it is full-time 4WD, yes. www.landcruiserclub.net/community/threads/centre-diff-lock-switch.145776/ Good thread here with the part number.

[@eyadmershad5072]

Hello I did this but unfortunately it didn’t work well. The vehicle now is shaking and it become sk noisy on high speed Any solutions ?

[@OzTrax4X4]

That doesn't sound like a part time conversion issue, unless you haven't tightened up the spool properly or something 🤔

[@user-dh9th8kq2w]

What time frame would you put on the job if you had to quote?

[@OzTrax4X4]

Are you thinking of doing it yourself? I'd honestly say if you're doing it yourself, I'd do it over a weekend.

[@user-dh9th8kq2w]

I’m a mechanic and installing it for a client

[@OzTrax4X4]

Well, that is something you'd have to figure out. With a hoist, it was done in about 4 hours going at a slow pace as I was filming it.

[@habiblalji8756]

Hello mate i have a 1993 full time 4 wheel 80 series cruiser...diesel automatic transmission...i keep screwing up my front diff...even when i free the hubs the front propellor still rotates...i assumed that once i have freed the hubs the load goes off but the diff still rotates which means the elaxles and all....is this kit the answer to my agony? 24:36

[@habiblalji8756]

I have changed 5 diffs already...like just the middle part coz the crown wheel gets eaten up even there's enough oil in there...some help would seriously make my life easier...I use the cruiser for offroading on hunting camps...Africa...tanzania 24:36

[@habiblalji8756]

What you just actually confused me because you replaced some parts on the rear side of the gearbox or the transfer...

[@habiblalji8756]

No diff lock button anywhere for Me on the dashboard anywhere

[@OzTrax4X4]

Hey bud Yes, you'll need a part time conversion kit and a centre diff lock button. You just can't install freewheeling hubs to make it part time as you also need to fit the spool into the centre diff which is in the transfer case. To answer your question, yes, you'll need to fit the part time conversion kit so it drives the rear wheels only with everything unlocked and the centre diff button in the off position. Terrain Tamer are in South Africa and they sell the kits.

[@habiblalji8756]

Thank you boss....your reply is much appreciated....will have to look for these guys in sa terrain tamers you say...

[@69429boss]

I bought an 80 with this conversion but it only works in 2wd with the centre diff lock button on. Is this normal?

[@OzTrax4X4]

Hey bud Might sound kinda dumb and obvious, but have you also locked the front hubs?

[@OzTrax4X4]

If you have locked the front hubs and it's still only operating in 2WD, then the electronic diff lock actuator motor on the transfer case may not be functional or the fuse/relay that operates it may be faulty.

[@69429boss]

@@OzTrax4X4 g'day thanks for the reply! When the front hubs are locked it works in 4wd fine, but if I unlock the hubs it acts as though it is in neutral and the car won't move in 1st gear. HOWEVER when I push the CDL button on the dash it moves. Got me stumped!

[@OzTrax4X4]

@69429boss Ah yes, that is because the drivetrain takes the path of least resistance. If the hubs aren't locked, then it will just turn the front diff and axles, not the front or rear wheels. With the CDL actuated, it connects the front axle with the rear axle via the centre diff.

[@leftardtroller]

I heard AVM hubs are garbage ?

[@OzTrax4X4]

The black ones are prone to cracking due to being manufactured with a cast steel drive ring. The red ones are the better high performance heavy duty ones which are manufactured with a heat treated carbon steel one, so much stronger. I do have a pair of AISIN ones ready to go, should I have any issues though and since having the kit in, I've not had a single issue with the red ones. Hope that explains the difference 🤠👌
