converting full time to part time 80

Geoff,

A fair few of the LCOOL'ers have done this mod - apparently one of the easiest to do.

I haven't got around to doing it yet on my 100s but it does seem an easy mod as per the Lccol site (in the tech section).

Why? unless you intend to keep it forever you won't notice any decrease in drivetrain wear, I never noticed any difference in fuel consumption running in H4 or H2 with hubs locked or unlocked and unless you fit free wheeling hubs you will still be pushing the front drivetrain via the wheels which is probably less efficient than pushing it with the transmission.

Why?
Why lose the superiority of the full time 4wd?
Toyota system is a lot more safe then part time 4wd ...
I have an 80 series and I'm driving for work every day a landcruiser 100 series. Some time my company rent a Nissan T/D .... and I can feel it!

I know 4WD-Systems promote it as a good idea, but then they have an axe to grind ... you can't fit their Lokkas to a Full-time 4WD.

thanks to all who answered,seems it's question that divides alot of people.thanks again !
cheers

Geoff,
When my front tailshaft uni packed it in I removed the shaft and drove it home (centre diff locked) as 2wd (rear) and for 3 days before refitting the front shaft. My observations were that the car definetly took off harder and basically flew.
However accellerating / handling round bends suffered as did braking. I noticed that when braking with 2wd it seemed worse compared to 4x4 where all wheels are working together.
As far as economy goes I didn't notice any difference.

best to leave it as it was meant to be if you asked me.

Geoff,

Had my '94 GXL done a couple of years ago (see post 29976 for some extra info). Have just come back from 6 months away and did not notice any reduction in capability. Fuel consumption? Maybe better, but certainly no dramatic change. The car does drive better and is quieter, but constant 4WD is good on the road as well as off so you need to consider that as well.

If you read the above post you will see that I had mine done for specific reasons, but if there are no problems with your drive train at the moment, my advice would be leave it alone.

Matt.

Hi Geoff,
I did mine before our trip last year because there was heaps of backlash in the drive-line (mostly from the front axle) and to get the improvement in driveability and economy. The backlash problem disappeared the other two supposed improvements didn't show up. In fact one thing that did show up was a horrible front end shudder that occurred after a sharp bump (always on bitumen). This problem never occurred while the front wheels were being driven! If I was doing it again I'd put my money towards having the front axle rebuilt, i.e diff, C.V., Joints and swivel bearings. Hope this helps.
