FJ-40 locking diffs

[SVFD]

Hey Y'all,
I'e had my 40 since i got my licence and it does great, but its lacking a little something when i do seriouse rock crawling. I was wondering about getting locking differentials for my 40 but don't know where to start. I know its gonna be a good deal of money, but i dont know whats out there and kind of worried about all time locking difs bc my cruiser is my primary mode of transport. anyone have any suggestions? thanks

Like Poser said, ARB if you have the $$$. They are air actuated, so you can disengage them. If funds are somewhat limited, lots of guys go with Aussie lockers. There several options out there (Detroit, Lockrite, LSD, etc). Do a search on here for lockers (like this one). You can even narrow it down to which brand you are thinking about buying. There is lots of info on this site about lockers, and which ones to stay away from.

A couple of links

ARB - http://www.arb.com.au/

Aussie Lockers - http://www.offroadlockers.com/


Good luck!

i think on average lockers run around $300, unless you want a ARB then its more like $750,. iv heard some good things about lockrite, auzzie locker and ARB tends to be at the top of everything if you have the money...

 

[PabloCruise]

I think ARB is more like $900.

Aussies are ~$350

I have an Aussie in the rear of my 40. Drives fine around town...

I wouldn't recommend an auto locker like an Aussie for the front. Definately go ARB front and rear if you have the money. As mentioned, they can be disengaged for street use. If you're only going to install one, an auto locker in the rear is fine for around town and great for trails.

Toyota Factory Electric Lockers

I'm surprised no one mentioned Toyota.

Other than price, Toyota lockers are my favorite. They come in Tacoma's and fzj80s, probably other models.

Good:

• They're Toyota OEM parts.
• An air system is extra work and equipment taking up space.
• With air, you still need electric, but not the other way around.
• Toyota lockers stay locked if the wires fail, ARBs need air pressure to stay locked.
• You can lock and unlock manually.

Bad:

• An air system is useful for other things.
• A rear Toyota electric is exotic and expensive; requires a Toyota full-floating HD rear end not imported to the US.
• They cost as much or more than ARBs, but you don't need an air system.

There are a couple articles linked from the Tech section showing the install.

The locker out of an fzj80 was almost bolt up minus notching for the actuator isn't it?

mechanical locker?

I've searched and asked before, but does anyone know if Ox is going to make a locker for Land Cruisers? I would love to have a mechanical locker rather than air or electric and I have heard good things (yeah, just hearsay) about Ox products.

Requires new longer splined axle shaft....

Believe it when you see it.

Looked at all the options and mine is my DD and only vehicle and has been for years, I will install an ARB air locker when:

1. I have learned how to pick my lines without lockers.
2. Can't make those obstacles after taking the right line/approach.
3. Can afford it. Rear first then front.

Have fun.

Do you mean Ox products aren't good or that you don't think they'll ever come out with a LC locker?

Which is available for full-floating axles, but not easily available for regular semi-floating axles.

 

[Poser]

In stock 40 width?

I would not bet two plug nickels that you will ever see an ox locker for a 40...

 

[ridgerunner]

Exactly. But you could build a semi floating Cruiser axle with an elocker... if you built a centered housing and had a custom long splined right side mini shaft made... Edit: *That doesn't mean you can swap an E-locker into a stock semifloating rear housing!*

In stock 40 width?

Sure, but not techically factory. 40 width FF with 60 short side (long spline) axle shaft.

Whoa, little old me educating the master? I must be hanging around here more than I should...

I didn't notice the "I have been told..." comment before, so it's heresay.

From this link in the Tech Links: http://blake.prohosting.com/hzjsixty/elock1.htm

"There are OEM long-splined axles available that fit 40 series axle widths (which are the same width as 45 and 55 series axles) and 60 series axle widths (which are the same widths as the 62 series axles). Some non-USA spec 60 and 70 series Land Cruisers came with factory cable locking diffs. These diffs are relatively the same as the electric locking diffs with the main difference being cable actuation instead of electrical actuation. The locking units work the same on the inside of the diff (with the exception of the 80 series fronts of course). Thus, the OEM long-splined axle shafts used for the cable-lock axle assemblies in the non-USA Land Cruisers can be used with the electric locking diffs. The long-splined axles needed are the long side front and short side rear. I have been told that for a 40 series front long-splined axle shaft you can use the long side front from a cable-locker equipped 70 series. (Note: In 1991, 70 series front axles underwent a change from the larger 9.5 ring gear to the smaller 8.0 ring gear. They also changed from cable lock to electric lock and went to the larger birfields. So, the front shaft from an electric-lock 70 series will not work in a 40 series axle--you must get one from a cable-lock equipped 70 series.)"

So it is a common piece and easily found for the North American market?



Master?


What-ever.



I wanted someone to post this up again, as installing a Toyota electric locking differential into a semi-float axle and even into a full float axle is not a simple bolt-in operation as has been insinuated by folks.
