putting a locker in the rear?

[DFW Rusty]

In the future I plan to put a soft locker in the rear of the disco and I was just wondering what my price range is going to be for everything(not exact, within a few hundred). When I do it, I want to do a locker, alloy axle shafts and all new bearings and seals(installing myself).

Thx!

Go to Bill's site and do some reading,http://www.greatbasinrovers.com/.
You should also go to , https://www.expeditionexchange.com/tractech/
and read up om the True Tracs and Detroits.
Round numbers on a Detroit and axles are $1400 plus labor.
I have been running a Detroit/T.T combination for 4 years and really like them.

(just for some numbers)

For detroit rear, trutrac front, and rear HD axles.. its about $3500 for 'bolt in' third members from Bill

For a trutrac rear, including a rebuild of the rear diff (it blew up), it cost about $1200

Detroits are harder on axles and and are the weakest of the main diff lock contenders.

Try this site for the best prices on TruTracs and Detroits. Honestly if you do a search you can find this stuff. That's how I do it.

I assume you have the tru trac up front, Detroit in rear

Why not Tru Trac both front and rear?

If the tru trac is on all the time, then wouldn't the rover tend to handle funny in loose surfaces at speed. I mean gravel roads, snowy highways, and slick rainy surfaces. You will tend to get wheel spin on both sides of the car simultaneously making your vehicle less stable. Although this is fun for those of us with rally driving experience, it is probably unsafe for those who simply don't know how to handle it. Easy way to get in trouble on road. Great traction off road.

Maybe the rover doesn't have the power to spin wheels on dry, but it will in slick weather. Wondering if the selectable diff lock is the better option in that case.

thanks for the advice.

Um, no. I'm running dual TT's and have none of the problems you describe. You have to "activate" the TT by tapping the brake or when traction control kicks in. It's actually a pretty effective set up on a D2 because of the traction control. That said, it's no locker but it's 100% better then open diffs.

I wanted to have a little extra traction from the rear cause I enjoy playing in the big rocks alot, TT's will do it but a Detroit is always locked giving more traction to the ground at all times.
I have had a number of friends that have gone with dual TT's and really liked them, less money also since you don't need to add HD axles.
What year is your truck again, I forgot?

1999 Disco II w/ SLS and ACE
2" OME lift (rear RTE airbag spacers)

similar setup to yours
I was thinking of using air lockers on the rear at some point until i heard about the Tru Trac. It sounded similar to a limited slip diff. If that is the case, then when you romp on it in snowy weather, you oversteer and/or understeer like crazy. With a big heavy truck like a rover, maybe you wouldn't due to lack of power to weight.

It is a gear driven limited slip. And once again, no you don't over steer/ under steer in slick conditions. Unlike a clutch type limited slip, the TT needs to be actuated with brake modulation or traction control.

wimp, stay with the idea of air lockers. A lot better system and more reliable. Also don't have to upgrade to HD axles like you do detroits, which makes them cheaper.

[Disco Mike]

I think you would like the TT in the rear better then a Detroit if you are going to be doing alot of snow driving. I mean, I live in Denver, we get a lot of snow and my truck works great. But if you are off road in deep snow climbing a hill and off camber a Detroit will make you crab walk a little.
Botton line though, either combination works really well.
