i have also heard of issues with LSD etc and TC but i haven't experienced it so cant comment on problems from my perspective.
personally i prefer a true locker that i can put in and out as required although i quite understand the need and ease of using automatic lockers. They are a godsend and its one less thing to worry about. Cheers James 110 2012 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

This has become quite interesting and I have learnt a lot so thanks everyone. With the Detroit locker (or a similar automatic device), how quickly will it lock the rear? Will it lock the rear at times when it really shouldn't be locked (e.g. in a corner on road)? When in operation, is does the Detroit locker lock it up fully, as with the ARB lockers?

Detriot locker is locked all the time and disengage when you turn right away. Aperenty they would better on long wheelbase vehicles and nowadays there seem to be a soft operated unit. I do not kno wif it works fine on slippery curves. For you depends on the use you will give to the unit. My ARB is since 2 years without problems on "normal and non-extreme conditions as I have std axles. Perhaps a Ditroit True trac would have been enough.

heres a link to there site....
http://www.eaton.com/EatonCom/ProductsServ...oitLocker/ a lsd would be an advantage, a detroit diff needs "driving around" on normal hard surfaces. an ARB or Kam Ediff would be my choice |

Ah, my mistake, thanks for that. So, it's normally locked and then unlocks when cornering etc. Makes sense in some way. Do you feel it unlocking and locking again on a dry road? Does it cause handling issues? I do like the idea of having a system which is so simple.

An automatic locker doesn't really lock in my eyes.
It is designed that way that it drives the slowest turning wheel. If the wheels turn at the same speed it drives both. I don't know what you mean with driving around? You can feel the detroit when accelarating and decelerating in a long turn, but you don't really have to change your driving habits. It might clunk if you drive like a boy racer but otherwise there is no problem with it. Would I rather have installed a ARB? Maybe yes but the ARB diff was about twice as expensive when I bought my detroit and next to that you need a compressor and the installation is much more work.

if you read this link http://www.google.co.uk/imgres?imgurl=http...s%3Disch:1 i had a detriot in the back of my old RRC v8. if would bang and make the rear hop if i powered around corners due to the need to unlock. not a bad thing in it's self but it can't do it any good! a pair of lsd's and a bit of cadence braking will make them work the a treat. |

Nice link, thanks. The Detroit looked fully locked up to me and therefore I'd class it as a real locker. How much torque will a LSD transmit to the other wheel if one is spinning or even off the ground? For example, the true-trac.

A detroit locks is a sense that it will drive both sides if traction is needed. but if you take a corner the outside wheel can rotate faster if neccessary. With a real locker like an ARB the outside wheel cannot rotate faster then the inside wheel. So forces your car to go straight ahead.
A truetrac works too, it has better road manners then a Detroit and can be put in the front axle too. A truetrac puts about 3 times the torque to the wheel with traction than the spinning wheel needs te get spinning. But if one wheel is hanging free and doesn't need any torque to spin? 3 x 0 = 0 So if you crosaxled a LSD like a True trac doesn't work unless you create torque at the spinning wheel by using your brakes. I had a truetrac in my rear axle first and it works but not as much as I wanted. So it moved from the rear to the front and bought a Detroit for the rear. I bought them when I was driving my Camel and I now transfered them to my 90.

I have always liked the mechanical locks such as ARB. In my Td5 110 I just used TC with a view to fitting ARB at some stage but never did. I now have a puma 10MY which is more reative with it's TC when compared to the Td5 and I really like it. It talks to me, tells me when I have the wrong line or have lost traction such as in sand with tyre pressures too high for the conditions. I kind of like to drive such that I can beat the obstacle without TC kicking in - choosing optimum line and tyre pressures etc.

Sand is one of the elms that i have found the current TC lacking in that it is too aggressive. so much so that it kills the engine power too much in deep sand and kills the vehicle from my experience. Sand and Gravel have been my two repeated experiences of TC. the newer system is a little softer in its first applicaton.

I just experienced issues with TC on soft sand in the desert. If you remove the TC relay for soft sand driving that sorts it.

Had an outing at Atlantis Dunes with the local LR club - tyres down to 1.0 bar and very rarely did the TC kick in.
It's all about the tyre pressure and correct gear in sand. |

Is it poss to use air rear locker with TC? It won't interfere with things too much?
I'm looking to transfer my Locker to a new vehicle, prob a TD5, but don't want to knacker the electrics!! 
Thanks all G |
