Doffs and locking options

[Brett_J]

Been looking at lockers for the Prado, standard it's open centres with traction control. I was looking at an slicker for the front, have seen the eaton trutrac for the rear, anyone had any experience with them or just go the elockers all round. Since it's for the rear I figured it'd be ok as it unlocks on turning etc.

I personally wouldn't bother with a detroit nowadays, with the proliferation and relatively low cost of e-lockers.

Just make sure you do both front and rear axles. I've got a ARB rear locker in my Pajero, and it plays havoc with the traction control in certain scenarios, i.e. long, slippery hill climbs.

E lockers from Eaton.
If front and rear wheels are all spinning at the same time then traction control should be thinking all is good.

Im in the process of pricing supply only for the FJ.

On lose rocky ground the traction stuff responds too slow when good control is required on recent 4 day 4x4 trip.

The trutrac is more of a traditional lsd, locked when going straight but unlocks when cornering to not fuck it, pretty much a torsen/Audi diff/mx5 diff

if you gonna have a car for a longa time,,,, detroit is the way to go... for rear... they will pretty much outlast anyvehicle.

plus you can make people shit themselves by making it lock in hard at a set of lights, just don't do it near a cop ;)

I've had detroits f&r and e-lockers f&r in a few vehicles

I wouldn't detroit a front diff again, it's a pingpingpingping to get them to unlock on tight tracks.
So definitely air/electric locker front
Rear diff either way is good.

After chatting with Harrop, the only option is Elockers or Air lockers, they don't do Truetrac for the 150 Prado.
So it looks like I'll do the Elockers one at a time, which would you guys recommend first, front or rear?

Edit*
Rear first, no lsd standard so will go rear.

Being IFS I'd go front first personally, generally where the suspension is most lacking.

Trailing brake method as a get out the shit option works alot better in the rear too

The only issue with that I have read is people breaking CV's if you lift a tyre and the front is bearing the brunt of the weight.
I might just bite the bullet and get both :)

I have Front and Rear Air Locker in my 120 Prado and use the rear the most but once the front is needed she will just crawl up most things. Also the front locker is great to get out of soft sand.

fj has factory rear locker which is sufficient in 99% of situations. id go rear first, you'd use it way more then a front. i spend most time off road in 2wd with locker on.

go with e locker, air lockers are a pain in the arse.

and trutrac is a waste of time, its still an lsd so if you lift a wheel it goes single.

[HotAe92]

Rear is more versatile, but the front will get you further when the going gets tough (especially with the Prado's 5-link rear).

Just fork out for both.

FJ rear locker is open wheeler at speeds greater than 10km/h.

ATRAC with 0 load on front axles don't allow the brake pads to pulse.
This is the reason I'm going the Eaton package.

Front first without a doubt, especially in an IFS that has a coil rear.
You can get flex out of the rear to keep tyres on the ground that should maintain forward movement.
Same cannot be said for the front, once you lift a front wheel you are in RWD mode.

The front pulls you over the obstacle, so once you are up it'll keep dragging you forward. Whilst the rear pushes you up, but if you don't have the front traction you will tend to slip and slide all the way up over the obstacle.

Interesting article

An article based on experience with only a rear diff lock, would have credibility if the experience was there.
So many assumptions in the article as well!

Another great thing with IFS is when the single wheel spinning in the air comes down and gets traction it tends to result in CVs shattering and diff centres losing teeth, fit a locker and you gain control over the throttle and minimise the potential for damage.

If you had a decent LSD i'd say front for sure, but open wheelers and you can only get one i'd do the rear first, you'd be amazed how far that will get you.
You saw how easily my big girl crawled over shit with just the rear, the tc system was effective on the front but could be slow to react.

Not once youve fucked with the wiring it aint.
