Detroit locker

[JimCT]

Finally got around to installing a Detroit locker in our ambulance's Salisbury diff. Actually pretty easy all things considered. Off to the trails tomorrow to see how it works. Getting it ready for the Winter Romp.

Well how well did it work. How long did it take to install and where did you source it. Looking one for my series III 88 and am interested to here how your efforts went and what suggestions you could add before I try and have a go at it.

Locker

it works great, something I should have done years ago. You need to have a Salisbury diff. Took less than three hours. So much better in the woods and in snow and ice

[KingSlug]

The only thing I would consider is to carry some extra rear drive members. Or did you get HD drive members when you bought your GBR axles?

I wouldn't suggest a DL for a 88, especially with the rover 3rd member and axles. On a longer and heavier vehicle like the 109 ambulance with a Sals the DL seem be tamed down, and have none of the ill traits except for when you pull into a parking space.

Drive hubs

We are using aussie built axles and hub flanges after breaking a Salisbury axle with the open diff. The Detroit is reworked of late, soft locker and you really don't hear anything even on a sharp turn. Can walk up bedrock steps so much slower, not needing momentum, so I think it will be much easier on the ambulance in general.

For an 88" still using stock 10 spline axles the Truetrac might be a better option for most people. At least that is my theory.

LWB+24 spline axles would make a Detroit more viable. Automatic lockers in a SWB can be screwy at times- slippery side hills and on snowy roads.

Any possiblility of detailing the conditions under which your Salisbury axle broke? Perhaps a subject for a new thread, but I'm curious to know what it would take to break my rear axles.

Thanks!

Broken axle

We did nothing extreme at all, and it broke like most of my LR axles have, pulling away from a stop sign. Bill at GB said they are not as bullet proof as one might think, and that the Aussies break them all the time, hence their up-graded axles and drive flanges. Believe me I was surprised, thought i was done with broken axles. Knock on wood but so far so good.

To put things in perspective:
Suzuki Samurai axles are 1.05" and 26 spline
Land Rover 10 spline axles are 1.10"
Dana 30/35 are 27 spline 1.16"
Salisbury and Rover 24 spline axles are 1.24"
GM 10 bolt 28 spline 1.285"
Toyota 30 spline axles are 1.30"
Dana 44 30 spline 1.31"
Dana 60 35 spline axles are 1.5"

GM 14 bolt:

Jim,

Are you still pleased with a Detroit in the Salisbury? ANy issues at all?

I'm thinking of doing the same in my 109 2-door hardtop...

[JimCT]

Still happy

The locker was probably one of the best things we have done to the truck. Walks through things on the trail that would surprise most folks. Great in the snow last winter too.

This brings up some questions from me. I have yet to learn much about axels, so here goes.

I have Stage 1 V8 axels on my ride. Out of the box are they 24 spline, right?

If so, that means this is the correct DL for me, right?

That one is for 3.54 gear sets. Your's is most likely 4.7's right? I'm not a Detroit expert but I think if it does fit you would likely need a ring gear spacer. You'd be better off pursuing a unit made specifically for the 4.7's if they make one.

I'm not sure what I've got. I just don't know enough about axels - I just know that the PO said they were the v8 ones.

take a photo and post them here...will help the rest of us identify what you have.
