centre difflock question

[Hobes]

hello all

i know discos are fulltime 4wd ...


does this work by engaging centedifflock in lowrange

does this work similar to a lsd in say a patrol or does the disco just have open diffs front and rear (therefore being technically less capable then say a standard patrol or landcruiser)

Start here:

Then buy a Land Rover. Technically more capable.:wink:

maybe,,
but has anybody answer'd the question? :?:

[Hellspawn]

I don't understand the question.

[Hobes]

Way I understand it, the rovers with their centredifflock locked is equal to a partime patrol or cruiser with their hubs locked in and in 4wd.
However it seems the latter have the additonal benefits of an lsd.


What do other people think?

yes

some models.

Some Land Rovers, eg Disco II and Defender Extreme have traction control which works better than a Toyota or Nissan rear LSD.

I'm familiar with both the open diffed, full time 4WD system of Land Rover (I have a Defender) as well as Nissan's part time system with rear LSD (My other half drives an '01 Patrol)
They both have pros and cons.
I'm more comfortable off road in the Defender (when it was stock) than the Patrol (still stock, apart from Koni dampers), due to a few factors such as the Patrol has less wheel travel than the Defender, I've always had better off road tyres on the 'fender, and if I lift a rear wheel on the Patrol, the LSD doesn't work anymore, so it's just like the stock Defender. The Land Rover has a lower low range reduction, the Nissan has much stronger diffs, axles and CV's for haredecore use, excepting the rear Salsbury diff used in pre '02 Defenders, which would be the most robust and heaviest centre section of the commonly available 4WD's.

I'd rather fit diff locks in front and rear axles, and both vehicles would be far more capable, although the Land Rover would have the edge with its better low range reduction. (which can also be changed in both vehicles with aftermarket parts) Wheel travel on both can be taken to extremes with judicious use of aftermarket parts.

hope that helps.

Thanks for info... Defenders haver better travel than patrols,,, does this mean the s1 discos have the same travel as the defenders (they changed the suspension setup pos S2)? Thanks for you help mate style_emoticons/<#EMO_DIR#>/smile.gif

Don't know anything about Discos, but my 79 Rangie has 3 open diffs.
The centre diff lock does exactly that. It locks the centre diff and provides equal drive to the front and rear.
It can be engaged in Hi or Lo.

The open diffs provide drive to the "easiest" wheel, and allows the vehicle to turn corners.

So without locking anything, it's possible to be stuck with only 1 wheel turning. However it's more probable to be stuck with 1 front and 1 rear spinning.

Diff locks for all 3 diffs is the go style_emoticons/<#EMO_DIR#>/laugh.gif

Some models - until the LSD wears.

But don't forget that back on the road, the full-time 4WD Land Rover will be better than the Patrol or Cruiser which will have had to revert to 2WD. The LR will only have had to unlock the centre diff. With the full-time 4WD Land Rovers, you don't have to unlock/lock front hubs.

The centre diff can be locked in both high and low ranges. It is a true diff lock, not an LSD.

You can, of course, fit locking diffs to the front and/or rear of the Land Rover.

i heard somewhere during extreme off road conditions, the Prop shaft axle joints become red hot. Specially the lifted vehicles with extreme angles between tranny and diffs.

Maybe the site was trying to say this, given fron and rear axles will be spinning at the same rate? :wink:

Extremely easy to check (oooh, that pun!).
