Land cruiser 80 series- AWD or 4WD?

Postby prado_boon » Fri Jun 28, 2019 7:03 pm

But if a noob question but I couldn’t easily find this out. I’m looking at a buying another land cruiser, this time a 80 series.

It’s 1997 with the 1hdft

No center diff lock.

So does that means it’s AWD?
What does the transfer box do In regards to the power front/back ratios or is it fully open?

Thanks

I've been researching this for two days now and I still don't have a definitive answer.

1) Is the VC only on the t-case's rear output ?
2) Does the center diff AND the VC lock when in low (or you've installed a CDL switch) or does the VC not lock up ? If so, it's AWD but with a LSD effect on the rear axle, right?



I'm trying to simply figure out if you can still achieve a 50/50 front axle/back axle power delivery, just like the earlier "center diff lock" models ?

Is this correct or not? I understand how viscous couplings and differentials work I just can't find out if the center diff still locks and the VC locks (or is bypassed somehow) when in "low" or you've installed a CDL switch.

All I can come up with is this ........

[img] 16.0 80 Series Specific Info
============================

16.1 Full Time 4WD
------------------
All 80 series Cruisers sold in North America and Europe are full time 4wd. In
Africa and Australia, a part-time system is still available. 80's produced
between '90-'91 have an open center differential which is lockable in 4HI and
automatically locked in 4LO. From '92 on, vehicles with ABS had a viscous
coupling that sent a maximum of 30% torque the non-slipping axle. The
differential is lockable in 4HI and automatically locked in 4LO.

I've just seen this:

http://www.off-road.com/trucks-4x4/tech ... 53202.html

"The Land Cruiser runs with an open center differential in high range (4HI). When low range (4LO) is engaged, the center differential locks, giving a true 50/50 power split to front and rear axles. It also shuts off the ABS brakes"



Soooo... it must disable the VC?!?!
