Detroit Locker Vs Truetrak Vs E Locker

A modern Detroit locker, marketed as a soft locker does not have the bad characteristics of older versions and other cheap and nasty 'Autolockers'.

Correct... but just voicing my experience and that there may be a different experience between a LWB and SWB vehicles

No issues at all although there was a note saying my luggage had been inspected. [biggrin]

Dumped all their cloths & personal items in the airport rubbish bins . Only carry on was engine parts [bigsmile][bigsmile][bigsmile]

Think they even ran the blow torch over them to make them look like 2nd hand parts [bigwhistle][bigwhistle] If my memory serves me well . Was about 30 years ago

Re the trutrac type diffs, I have seen them in a Disco that had the individual wheel braking system [ traction control maybe ? ] Very impressed how well it worked .
If you don't mind the extra complication of the later model vehicles , it is a very good setup .

I hadn't even thought of that but yes, I'd imagine that traction control would provide enough braking on the slipping wheel to make a True Trac work very well.

Yes but is the True Trac providing the traction or the traction control - TruTrac is just a good LSD not a locker and if you want a locker well you need to get a locker.

Completely not applicable in my application but if we take as an example my 130 which does have traction control (and an E Locker, but that's not relevant) If I wanted a "better than traction control" device for the front diff I would consider a True Track. The main traction scenario that I have experienced being an issue with that configuration would be a front wheel waving in the air and having zero traction, traction control would cut in once sufficient spin was detected and would allow transfer of torque to the other wheel but with the 130 traction control is nowhere as good as a Disco 3 or 4 and on really steep terrain the additional scrabbling rather than having a locked axle is less effective.
As a way to bootstrap traction control I reckon a Truetrac would be a good addition as the traction control would effectively trigger the Truetrac to engage and remain engaged until the wheel gained traction. This is the situation that I'm thinking of, I didn't make it up this hill on Macfarlaines track and needed a tug, it was before I had a rear diff lock but traction control wouldn't cut the mustard with multiple wheels with low - zero traction and I think that a truetrac would be one way of solving the problem

We're way off topic from my original problem and the Detroit locker is on order for the Jeep but it's an interesting discussion that shows that there are many ways to solve a technical problem each with benefits and disadvantages.

Yes I agree that a diff lock in the rear and a Tru Track in the front is a great combination but your original post was about a locker in the rear not the front.

In all the time I have had my Detroit in the rear of the 101, I have never felt the need for a front locker (even though I do have a ARB under the bench ready to go in). Likewise, in my manual double locked Haflinger, I regularly use the rear locker but have never had to use the front locker in anger.

Go a locker in the rear as you asked originally, but a TrueTrac over the standard LSD in the rear will not deliver much extra capability especially when cost is taken into account.

Yeah, the locker is ordered for the Jeep, and it's unlikely to ever need anything more, the rest of the discussion is purely theoretical :-)

A follow up on this one, the diff is back from being rebuilt with a Detroit locker. Driving around town I was unable to provoke any noises from the rear despite driving around in small circles on bitumen to see if I could prompt a reaction. The only thing that I did note was a slight sideways movement when leaving our driveway with the rear slipping a little on the loose gravel. Overall very happy with the vehicle and the rebuild that was done by JMAC in Arndell Park and who were recommended on here as well.
