Limited slip diff upgrade

That was a brave move Andrew , I couldn't concieve of putting and extra force on the steering control , it would be likely to understeer one off the road in some of the icy conditions we get in Victoria .

Good to here your happy with the E-locker , my automotive engineer brother decided they had weaknesses in the electrical connections and went straight for twin air lockers (80 series).

Hullo Robin
Since fitting the lsd to the front, I have done many thousands of kms on open surface roads and not had any issues - it feels very sure on corners.
As to icy conditions, I am yet to be in a position to comment. In the few times I have had to drive in such conditions, my general approach has been drive as if the road was covered with ball bearings :-)
BTW, it is a constant 4wd model with viscous coupling

Hi Andrew

Thanks for the reply. Just what I needed - first hand experience.

When you where deciding why not just fit ELockers front and rear.

I believe the 80 series and 70 series have the same rear diff and same front diff so might be a problem for me if I want a Truetrac in the rear diff.

I find there are many situations where a bit of extra traction is handy "on the go" without having to stop and engage a diff locker.

My previous 4wd was a Pajero which had a good lsd in the rear. I went most places without engaging 4wd. In fact a good piece of advice I received early was use 4wd to get out of trouble, not into it! :-)

Now that situation has changed as the LC is a constant 4wd. As I couldn't fit an lsd in the rear, it went in the front. The ELocker is therefore the "back-up" to get out of trouble.

I must confess I am a front wd fan in my normal cars - the fact that the front wheels pull you in whatever direction you turn them, rather than the car being shoved from behind by the rear wheels, is pretty handy IMHO.

So it is with the lsd in the front of the LC - you know that the front wheels are always pulling you in the direction you steer, rather than one (possibly) spinning and the other being shoved (if that make sense - it does to me ;-)

I might add, the "need" for a bit more traction was really as a result of getting a C/T and having a bit up my sleeve as "insurance" in tricky places. Care for the environment and minimising track damage is high on my priority - I have a sign in the car that says "Just because you can, doesn't mean you should"

Andrew,
David has a part-time 4wd and you have a full-time 4wd - very different when you're considering a front LSD.

Hullo Phil
You may well be right.
I guess my thinking would be as follows -
If the rear diff is the same as the 80, then my understanding is that there is not a Trutrac to fit it.
If he wants one of each, David could then still decide to put the Trutrac in the front and use it when he needs 4wd - for all the reasons I have stated above.
And also put a locker in the rear if needed.
Or, like you, put in a locker front and rear.
Cheers
Andrew

Gday Andrew,

The way I think is:
- When its in 2wd and the hubs are unlocked, its all irrelevant.
- When its in 2wd and the hubs are locked (I do this on most bush/desert tracks) it will have no drive to the front and the front LSD action may give some unwanted understeer
- When 4wd is engaged, it will work as a front LSD - not sure whether this is of any use unless climbing over rocks and lifting wheels. In this situation, the weight is firmly over the rear anyway, and my preference is to have the rear locked, or both F&R locked.

So I guess I'm a bit of a pessimist about a front LSD on a part-timer.

But I haven't really considered a fulltimer like yours with a front LSD.

Hullo Phil
You are probably right
I had forgotten that the 79 has not got a centre diff.

Hi Andrew

Do you remember how many spline axles in you rear diff.

I sent a message to Harrop/Eaton regarding a rear TrueTrac and they said they have one for a 30spline axle.

Of course I have no idea how many spline axle are in my new cruiser without popping an axle out.

Cheers

David

David,
I'm amazed that Harrop/Eaton can't give you that basic information

According to the ARB website:
The 76/78/79/100/105 series rear diffs are all 32 spline and have have a 34.8mm shaft.
The 75/80 series have a 30 spline and 33mm shaft.

Cheers
Phil

Well after reading that it sort of blows any chance of getting a Truetrac rear diff.

I was quoted about $2000 for the installed truetrac or $1600 for an ARB locker or $350 for an overhauled and tightened toyota LSD.

Hmmm looks like I am stuck with the toyota LSD for a while longer unless there is some other after market LSD.

Thanks all for the info

Cheers

David
