On a Puma it works across both axles together,

Not wanting to be argumentative but I cant see how that this the case
This TD5 Traction control appears to work on both axles
I am not disagreeing about the locking of the centre diff though

At the risk of highjacking the thread- Fit lockers of some sort, Preferably Air Lockers (IMO) You won't regret it. By the time the traction control has worked out it is needed you would have engaged the locker before the obstacle and driven though, round or over it.

Nino.

I thought you were'nt allowed to read the Handbook if you wanted to be a Real Man....:p

bzzt, sorry, but dont worry a consolation prize is coming your way....

check your pads and rotors. if the pads are glazed, the rotors polished or either contaminated you can wind up in this exact situation.

as its a 2001. unless its been rebrained it will have the early TC so you need to be a bit more agressive to get it to work properly. That Said.

TC is a warning that you are approaching the limits of the native capability of the vehicle, nothing more.

With the CDL locked TC works across each axle. TC is still working on both front and rear axle, but only compares the speed of wheels on the same axle. So wheel spin on the front axle doesn't influence the behaviour of the TC on the rear axle.

I suppose that is the reason Real Men try to drive a Land Rover like a Land Cruiser, and why they hate Traction Control :D

EXACTLY -- That is what I was trying to say, but you said it more eloquently.

Actually the perfect diff for cars equipped with traction control is the Eaton (detroit) Truetrac , Not to be confused with the Detroit Locker.

I reckon it better than a Manual difflock because its operation is seamless , quiet, gradual and much nicer on your axles and driveline, and totally benign when on the highway.

Truetrac and Traction control compliment each other.

good value too the front inc bearings was $634 au to my door
and the rear (Salisbury) inc bearings & shim kit was $925 ($300 of that was shipping)

some info here http://www.alljeep.com/tech/install/..._true_trac.htm

When I get into a situation where my diagonal opposite wheels are off the ground & car is teetering, It just keeps driving, I can not even hear the Traction Control operate, Same situation before the car (TD5 110) would sit there for about 5 seconds before the brain engaged & the car would grind its way forward.

Rubbish!

My Puma is now 2yrs old with barely 31,000km on the clock. Of that, we have done 3 mild off-road trails (2 sand, one rocky), with TC barely kicking in. In fact, I can count the number of times TC has kicked in when we are off-road on one hand - CDL is always locked and tyres deflated.

The rear diff was replaced a couple of months ago and so was the gearbox.

So no, it can't be the TC causing all these diff failures ;)

I actually think I have a valid line on why the puma back diff and and rear Tcase outputs are not lasting...

And you're not going to believe it But if what I think I've found is correct, Landrover has already visited and solved this problem previously.

Check out the angles on the rear shaft flanges and the shaft phasing.
