Just looking at an advert for another landy which says it has a detroit locker in the rear but no way of proving this. Is there a simple test that you can do with to test whether it has one or not, thanks

If you drive on slippery ground a locked diff will be quite noticeable.Best is to put one side on a rock or suchlike and the other side on grass or ice is even better.Pull away sharply and with an unlocked diff youll get plenty of wheelspin on one side.Locked you wont.If you cant drive it you may be able to see the diff carrier through the oil filler or drain hole try a torch and dentists mirror.The carriers look totally different.Ive often had ARBs but found them fiddly thinking about detroit cos they are so simple:)
 
ive got a detroit locker in rear of my 90,there really good as you just fit & forget,the easiest way to check your possible new motor if its got one in is jack both rear wheels of the ground (hand brake of & front wheels chocked) spin one wheel by hand,if its a normal open diff the other wheel will spin the opposite way,if its a detroit locker the opposite wheel will spin the same way and you will hear the locker click as it engages
 
easy way is to jack up both wheels at same time and turn one of them, the other one will turn the same way and at the same rate as the diff will be locked in.

the diff is locked all the time, its only in cornering it unlocks.

i know this because i have one in the back of mine and also i have alot of large skyjack sissor lifts at work which also run them in the rear, they like snapping half shafts too lol

personally ive had no trouble/uneven tyre wear on the roads,ive had it in about 4 month now,i find it engages more when in diff lock as you allways got drive to one rear wheel which obviously will engage the locker,probably the only thing i have noticed is pulling out of a junction fast or hitting a roundabout hard on a wet road,cos it locks up the rear you tend to get a slight bit of understeer on the front end which im going to sort by installing a detroit truetrac lsd in the front;),personally i think they really good and a lot cheaper than arb's or kam's and off road they really do make a differance
normal road driving you dont even notice you got the locker installed

:):)thanks a lot 19mart82 thats great info. i take it pretty easy on road and especially with the trailr on and my truck is less powerful so i think i can cope with that easily.It was my plan to fit the tt in the front too.You aint kidding about making a difference ive loved em sincei first met them on tractors 30 years ago.I found the arbs were good but the compressor and airlines were a pain
