Arb Locker?

[wyorunner]

I have been looking at buying a locker for my 02 Sport V6 4runner. I have found numerous part numbers for the rear and i beleive just one for the front. Could somebody please help me on which one is the correct one for my rig. Ive found RD90 for the front. And then RD23 or RD132 for the rear. Im sure somebody has a definant answer for this. Also Is there an electric aftermarket locker out there for the 01-02. I havnt found one if there is. Ive looked at Eaton, Auburn ected, researched the retrofit option and i think the cheapest and best way (maybe the only way) to go is with an ARB. Thanks guys

RD90 for the front
RD132 for the rear...assuming you have 4wd rear end. Hey ya never know...LOL

Are you doing a gear change?? If so you will need a master install kit for both with the gears. I would do Yukon gears. If not...how many miles do you have on the diffs now? If alot you may want to do new bearings and such anyways and the master install might be worth it. You will also need a compressor with the lockers. If you like the ARB and can afford it....It's really the best way to go. Shoot me a PM if you want a price dropped shipped to your door.


EDIT: I'm not 100% positive on the part numbers....too many to remember for to many years...LOL But I'm pretty sure It's right. I've been wrong before...LOL

RD23 will fit the rear, but that part number was discontinued, although they come up for sale occassionally. ARB redesigned/combined it and another part number to produce the 132.

Personally, i would just get the rear ARB locker with air compressor. I would NOT get a front locker because your front is independent suspension...may not be strong enough to handle the abuse of the front locker over the long haul (if you off-road a lot). Anyway, i think that ARB rear locker + ATRAC (for front axle) is pretty damn ideal for most applications.

Oh yeah, i would go with ARB over anything else out there....

 

[wyorunner]

awesome thanks for the information. thats on my next todo list. then for the shrockworks bumper. im going to have a pile of parts to install when i get back from iraq. im buying them already and i havnt even left.

Running a ARB up front in a IFS rig is is doable. The front is a bit weak with the IFS, as long as you dont turn your locker on under power and dont bind up the rig on rocks or tight turns you should be fine. I have friends that have run them on Tacomas for years and they are fine. I dont see anybody abusing a new gen 4R that would break a IFS locker...unless you are doing something wrong....LOL

I have read over on iH8 mud that a rear locker only is the best because you still have A-Trac up front and you still have the ability to turn. You have to lock the CDL to do this....keep that in mind.

A-Trac has proven itself to be a very useful tool and full lockers are only necessary in un-imaginable situations.

I beg to differ on the latter one.

In sandy situations, lockers are very excellent, and many more.

Lockers in the front depend really really much on the places you are wheelin'.

In snow front lockers are fairly superior to rear, and it doesn't bind the turning that much.
But in rocks, sand and probably mud aswell, rear locker is a better choice I would think.

One example 'bout lockers vs tire sizes in snow:
My friend has Hilux with front locker (sometimes in the rear as well... lol).
At 1,5psi we make through almost the same snow. he's only running 38s, vs I'm running 44s.
The same situation I've seen on 33s vs 35 or 38s even! So a locker makes up a whole lot for traction.

Just my few thoughts.

About that A-Trac I'm not so sure, I've never driven a 'runner with A-trac and I think there is none on the whole Island, so...
But I guess it can work pretty well together with ARB in the rear and open front diff.

I totally agree with you in the snow.....some real deep snow; however lol.

Pfft, I've had snow running over my hood on the 44s, still battlin' on, and behind me is a 35" hilux with snow up to the front lights, still battlin' on, because of lockers in front and rear. So... I think fully lockers (not no-spin or that detroit stuff that eats axles for lunch) really in some cases do wonders!

I, btw don't have lockers, save the puny deadly LSD in the rear. (tried to kill me a few times, thankfully my wheelbase is near to 8' so it helps up in the stabilty control)

Conclusion: ARB lockers 4tw!
Wont get you killed because of the locker decides that now is a good time to lock the diff... lol

Unimaginable situations?? There are thousands and thousands of very easy situations to get into that require f+r lockers. Head over to Rausch Creek in PA one day and you'll see plenty.

A-trac and any other traction control systems are excellent and do great offroad, but time and time again fully locked always proves itself to be the best to keep you moving. No matter how good the trac system, they are always 'reactive' and not pro-active.

I'd rather get stuck at an off road park than destroy my IFS...unless im alone on a true expedition rescuing starving jungle kids in the Australian outback....where I would only want a land cruiser

yet, the Australian army is using G-wagens (fully locked)....

I totally agree with Techno...if you have never off-roaded with a fully-locked vehicle, then you have not experience the superiority of a fully locked vehicle over everything else. No technology at this time can match the off-road capability of a locker(s).

Having said that, i would still NOT recommend a front locker in ANY independent front suspension of any production civilian vehicle, except the late Hummer H1.

 

[fourwd1]

What you've heard or read somewhere else just can't compete with actual experience.

Maybe those that aren't locked front and rear should keep their opinions to themselves in this thread, it's about front and rear lockers (at least it was, I think )

And yes, your type of wheeling, vehicle, and wallet will govern the type of locker you have, if any.

If you wheel hard and want to do the really difficult trails, a locker or 2 is handy. And if you keep wheeling like that w/o them, people will get tired of dragging your ass out sooner or later.

If you don't wheel hard, you may not need 2 (or even 1) locker.

And you can wheel pretty hard w/locked IFS, if you know what you're doing, I see it a lot. If you don't, you'l get tired of replacing CVs and learn.

ah, sorry to burst your bubble Thai, but the RAR use LandRovers Landcruisers, Perenties and Unimogs (which are from Mercedes Benz). Mercedes dont sell the G's in Australia.

And jungle kids in the outback?? WTF? But I would take a Nissan Patrol there anyway..... oh yeah I forgot, I have taken a Patrol across the Simpson desert and used both lockers many times.

On a side note, a mate of mine who lives in Melbourne drives a very well equiped 100 Series LC V8 IFS, Air Lockers front and rear, bullbar with Warn M10000, ARB RSTB, all jacked up with 35's. He's been wheeling that very hard for 10 years and broke his 1st cv last month crossing the Simpson on a tricky dune. He had to drive about 500 miles off road with only 2wd and the rear locker.
IFS can withstand some pretty harsh treatment. The Toyota Hilux never has any issues with its IFS and hundreds of lockers go into the front of those.

No bubbles burst here...i am just more updated than you! This is a major change in thinking because, as you stated, Land Cruisers and Land Rovers used to rule Australia...Mercedes have not sold G in Australia since the 1980s i think. So, Australia is yet another country that will now have the G as an official military vehicle. (BTW, the G-wagen is also currently the longest running production vehicle to date...30 years and counting with NO major redesign...no current vehicle [Land Cruiser, Land Rovers, etc.] can say that!)

Here is a list of militaries that use the G: (scroll down) http://videoinside.org/show/Mercedes-Benz_G-Class

Oh yeah, here is the article on Aussie + G in 2007:

Did he tell you about the infamous issue of broken/crack IFS lower control arms on TLC100 with aftermarket bumpers?? This is apparently a common issue among TLC100 with aftermarket bumpers due to high speed travel over rough Aussie terrain.

Very interesting on the G, I stand corrected. Yeah, the lca issue has become more common lately as the vehicles age, but I am not aware of it being directly related to bumpers. From my experience its more from the hard use the vehicles get and since probably 90% of offroaders have bullbars in Australia, thats what some would like to blame. I worked for ARB for several years before I moved to the States, and I would see those vehicles come into the workshop every now and then and every single one with a suspension problem had had aftermarket suspension fitted (of course, why else would you take the problem back to arb??). The Prados have a similar issue too. Fortunately, a significant proportion of LC's are solid front axle in australia, and they are very strong.

Well, the Prados and, now the FJ Cruiser also have inner front fender crack issue...and Toyota seemingly does not have a fix for this either. (My brother has an '08 FJ and is worried about this.)
