tru track for sals question

[Vern]

Looking at locker for the front of my project and was/am keen on a tru trac, problem is my project will be getting a front salsibury conversion and apparently the tru trac is only for the rear of the sals. Can some one tell me what it is they do to the rover (banjo) tru tracs to make them for the front and rear, from what i understand the gears are swapped around or something.
Anyone?

The preload differs between the front and rear Truetracs,

the rears are set a bit stiffer, in the front it will want to straighten up quicker like you have more caster,

Looking at locker for the front of my project

Noting of course that the Tru Trac is not a locker.

If you require a locker in the front you will need to look at something like a ARB air locker.

would love to know the answer to this question also. From what I have seen, it may be as simple as pulling it apart and swapping of the gear sets so left is right right is left.

It's ok now for some reason thanks Ben, after I went offline and just came back.
I wanted to ask Vern what type of CV joints and tyres he was intending to use on his Sals front? I built and used a front Sals for my 2a years back.even when shaved the lack of ground clearance on 35'' tyres was more noticable on the front than the back. Even a built 24 spline Rover diff will eat standard AEU2522 CVs.To adequately exploit the potential of a Sals front would require either Ashcroft replacements or graft the swivel ball/CV assemblies from either a FC101 or 80 series LandCruiser.

where... tried to search true track.. didnt come back with much. Is this on his website?

Earlier in this thread - post by Ashtrans.
(and there's no "K" in True Trac maybe why a search didn't find it)

i know the difference, its easier to say locker:)

Wagoo.35's and county cv's for now

Daveso could the preload be slackend off a bit, then would it work ok?

I have a tru trac that came out of the back of a 98 disco in the front of my county and fitted 24 spline axles and it works great both on and off road and it doesn't overload the front CV's like an ARB airlocker. It also doesn't shock the axles like the auto lockers

It also doesn't provide 100% drive to the wheel with traction if the other is off the ground or has no traction.I've heard numbers as low as 40%

Try 0%. The TTs I have seen in action will just spin the wheel in the air and the other is stationary. They need some resistance from the wheel without traction to work.

Sorry ben.. having an off day.

Simple as preload. Sweet

[Vern]

I think Dave (Ashcroft) said the front ones are same as rears but with less preload.
If you are going to the trouble of making up a Salisbury front, why then choose a half baked locker?
Have you figured out what you are going to do with the steering trackrod?
The Salisbury low pinion won't clear a straight track rod even when the diff is tilted up significantly, and I think the 1 ton defender shaped rod hangs down lower than a standard one.

Vern was asking if you can reduce the preload of a rear for the front, as they apparently don't make front sals tts.

HOWEVER - they do make D60 fronts - which are the same:
Detroit TrueTrac, Dana 60, 35 Spl, 4.10 & Down, Front Only (http://extremeaxlesales.com/detroittruetracdana6035spl410anddownfrontonly.aspx )
The only issue is the bearings (which keith at rovertracks has the PNs for) and the splines - which are better than puny rover 24spl anyway.

I agree with Bill though, why go to all that effort if you are fitting a crappy LSD. You can probably run 38s on a rover axle with a TT and ashcroft R&P without breaking things - the TT is much easier on the axles than a locker.

I take all of the above back if you are running ETC (ETC + TT ~=~ real locker)

[Vern]

yeah track rod bends under the pinion, will be making it up the same as the one ton ones.
Reason for the tru trac is to keep it simple, if i'm not happy with it then i can always pull it out and sell it off.
Just want to know if it will work thats all:)

[Vern]

for those who want to know, the gears are cut different between front and rear tru tracs, apparently its a strength thingy according to Eaton.
So it is not recommended:(

if i'm not happy with it then i can always pull it out and sell it off.

Can't imagine there will be much market for a 2nd hand FRONT sals TT in AU or the uk - it won't fit an FC101 or one-ton as it will be the 4.1:1 and taller centre.

[cookiesa]

I would go as far as to say the TT and indeed an open diff CAN be harder on the axles than a locker.

Most common way for axles to be busted is a spinning wheel coming back in to contact with a high traction surface (eg wheel lifts, spins than grabs as it comes back in contact with the ground) often followed by a loud crack and little/no drive.

A locker (true locked axle style) has the wheel turning at the same speed as the ground as it comes back in to contact no sudden stopping of said spinning wheel/axle combo.

Now hitting the locker "on button" whilst said wheel is spinning, especially with nice large tyres is also a sound way to break things.

The beauty of a locker, when used appropriately is it removes a lot of loads off of the driveline preventing damage.

[Vern]

Can't imagine there will be much market for a 2nd hand FRONT sals TT in AU or the uk - it won't fit an FC101 or one-ton as it will be the 4.1:1 and taller centre.won't the one ton be 3.54? thats what i'm running, also IF it was just a case of setting the preload, then couldn't the preload be set back to standard?
Anyway this is not the case as it won't work anyway, hence my original question.

AFAIK factory one-tons were only made until the end of S3 production, and were all 4.7:1, (though none officially made it to AU).

Coiller front sals were fitted to armoured cars or similar, and many were likely 4.7:1 to cope with all the weight).

[Vern]

sorry was thinking of the armoured vehicle diffs, will check the ratio with the one sitting at Hiline 4wd.
plus would only be selling the locker, not the gears.

3.54:1;)
