Thread: Truetrac-Difference between front and rear?

The difference between Front and rear Truetrac is the gears are the oposite way around. I put a rear truetrac into the front but had to pull apart and flip the gears around. Not that hard and there is a procedure on Disco Web.

I think the Detroit can go front or rear without mods but you don't want to do that in a constant 4WD car.

Is that all ?

Often a different bias ratio is used front to rear.
Pretty sure Quaife are one that does that, not sure about Ashcroft's ATB.

Yep that's all for a Truetrac.

Here is the link.

Flipping Truetrac Gears

a trutrack can go front or rear, yes internal gear orientation may need to be set, depending if unit is mounted in rear and needs to be moved to the front or vice versa..
a detroit locker is not reccomended upfront, due to it's nature it will cause steering issues in more ways than one, to include lack of turning, difficult in turning, binding of front end, loading of drive train all of these on a street vehicle.
for competiton vehicles, here in the us many drivers will use a spool at rear and a detroit upfront, it is not until the last 10 yrs or so that arbs have begun to show their head in competition.

Thanks for that guys, yeah, know all about Detroits in front axles. They were fitted in some Massy Ferguson tractors from new in the UK and called no spin diffs. They worked well but made the steering very heavy in soft dirt!

as mentioned Truetrac front and rear are different, & have different part numbers. I would not be pulling one apart to swap the gears around, the warranty will be voided. the carrier is final machined after assembly in the factory.

I was told this is perfectly ok to do by Keith (Rover Tracks) and Lucky 8 in the US. Lucky 8 sent me the wrong diff and said that flipping gears is the only difference and gave me the procedure. If buying new I would go for the right part but if a cheap one came up from the other end then go for it.

Just gotta wait for that cheep TrutrC and Detroit to come up!
