Factory Locker revisited

Jay · 12-09-2002, 08:20 PM

I think this may be one mod I am going to have to do. I regret the fact my truck lacks this option. I check with my parts dept. and he says it doesnt appear there is an option for 4.10 gears in 98' with a locker. I understood this to be my current gear ratio from a chart I no longer have access to. Anyone know of a factory locker combined with 4.10 gears from the factory?

No, but I thought the locker option came with 4.30 gears. But that may be just for the 4Runers.

I'll try to find some definite info. You're at home and don't have access to the database, huh?

Part number 41110-3D030 for the 4.10 ratio electric locker carrier.

If your Tacoma didn't come from the factory with a locker, you have the 8.4" diff. The electric locker will NOT fit into this housing, so your options for a selectable locker are:

1.) ARB air locker
2.) Complete V6/turbo 8" rear axle (housing & 3rd member) from a e-locked Tacoma. I would say 4Runner also, but the suspension is different.

My vote is for the ARB since that will probably be cheaper, not to mention less labor intensive.

Here's a chart of axle codes.

Hope that helps.

If your current axle is the 8.4 rather than the 8.0 inch ring gear than you may want to swap axles from a junkyard truck such as this. Car-part.com comes through again.

Shipping from Alaska may be pricey but $500 for a complete Tacoma axle with locker is worth it.

Jay · 12-09-2002, 08:39 PM

B03A is my code. But I have a V6.

What do you think? My plan is to find a e-locker used, and do most the work myself. Looks like fun.

FYI a new e-locker at MY COST (unknown gear ratio, randomly chosen) was 746.00, where I work.

ARB will be cheaper. So will a TruTrac or similar device.

Ahh... great job jx94148.

Ill look into that.

Jay

Jay · 12-09-2002, 08:44 PM

If I do it, it would be with the Toyota locker. Im just that way.

I can't imagine why that would be...

jruz · 12-10-2002, 08:12 AM

Phong is right...you can't just add the Yota locker to an unlocked diff. The TRD models (the only ones that came w/ e-locker) came with a larger R&P (8.4", all others were 8"....I think).

Without swapping the whole axle, your only option for a selectable locker is the ARB.

Actually the ARB is probably a better bet. The e-locker sometimes has trouble when it's wet (ask around). Plus, when you add the ARB you give yourself on-board air to fill up the tires.

Jim

jruz · 12-10-2002, 08:14 AM

...er...strike that, reverse it.
8.4" -> 8"

Jim

WATRD · 12-10-2002, 09:26 AM

Jim is entirely correct on this one. If you didn't have the locker from the factory, you can't just swap it in

The ring and pinion are a different size, so it's an axle swap or ARB.

Personally, I would prefer to have the ARB over the e-locker I have back there. It is unpredictable in wet conditions.

BTW, I have 4.10 gears and am locked, at least for the moment...

Jay · 12-10-2002, 10:05 AM

Oh damn. Thats bad news.

huh? You guys are saying Jay has the 8.4 diff right? If he had the 8" diff (like I do, 95, v6, etc) then he has to modify the axle housing. No swap-in, but still it is do-able. And worth it.

WATRD - what do you mean by the statement that the elocker is unpredictable in wet conditions? Do you mean the electronics have problems? Maybe I understand that statement now, I thought you meant it acted different than the arb when locked up on wet stuff. Anyway, you can lock/unlock the elocker manually if you have to. If you blow a line on the arb, it gets unlocked. That can be bad news in some cases.

Jay - I'm surprised at the price you would have to pay for that. Makes me feel not as bad. Oh, I was quoted about $1000 for it, but the guy would have given me 25% off. Still, I got mine used for much less

Jay · 12-10-2002, 10:48 AM

Yes apparently, poplular opinion is that I have the 8.4. So my option is to replace the entire rear axle assembly. Possibly still do-able. Ive seen some used complete axle housings for cheap. Ill keep ya posted.

Not sure about the date on this thread but...i was looking at the chart for axle ratio then found this one the chart says that my truck a 98 TRD with locking diff has 8.4" 4:10 gears. Why can't Jay put a factory locker in? Did I read something wrong?

Because the factory locker was only available in an 8" diff.

This thread is like 1 1/2 years old lol. The E-locker only came in 8" ring gear axles. If your truck has the TRD package with the E-locker, it has the 8" rear axle as apposed to the 8.4" rear axle.

you don't have a "8.4" diff, he did, you have the older style 8" v6/turbo diff, the "8.4" diff never came with a factory locker
