AXLES!!

[yotacruzer93]

hey guys i am new to this fourm but i gotta couple questions for anyone that can help me answer them.
how can i tell wat gear ratio my back axle is? and is the back axle of a 92 toyota pickup a high pinion or standard pinion? i know that is kinda a noob question but i have never heard the difference. I am also looking for a locker but i need one at a good price. i would like a selective locker but i am open to all ideas.
i have looked at the powertrax locker but does it really work when i need it? i am using this truck for a daily driver but i also run it in the local mud bog just for fun.
btw the truck is a 92 toyota pickup that started with a v6 and a manuel tranny that now has a 350 LT1 and a 350 tranny. i am running 35x12.50s currently with 7 inches of lift and soon to be 9 in order to fit irrigation tires

turn your rear tires one rotation and count the # of rotations at the pinion, that equals your ratio. (prolly 4.10)

low pinion

buy a lock rite or an aussie locker, if you want selectable you can go arb, or trd, and there are a couple others out there.

Yes the auto lockers will work whaen you want and and wont work when you dont want.

Your truck is way too tall, and assuming its still IFS...its scary as s***.

And SEARCH, these are all very basic questions.

x2, Start in the FAQ...

And if your truck has 7" of lift, 35's, a 350/350 then why are you worried about the on-road manners of an auto locker?


To tell if your diff is a high pinon, visualize a center line at the diff. If the pinion goes in real low it's a low pinion, if it looks odd how the driveshaft goes into the pinion, and it's real high, it's a high pinion.

The only axles I know of that go in the center are weak Rover axles... Something like non-hypoid or spiral bevel, I can't recall right now. Their pinion isn't designed to have as much contact with the ring gear as possible. Tilting the pinion does this, hence the low or high pinion.

Yes the auto lockers will work when you want and and wont work when you don't want.

It's a simple power-on, power-off type deal.

when you turn a corner, you're not supposed to do it under power with an auto locker. Backlash will let the teeth on the outer side, IIRC, skip over the inner teeth and that creates the ratchet sound everybody hears.

Once the diff has power, the pinon in the case forces the two sides of the locker apart causing a spool.

Keep in mind though, there are lots of power-off situations besides turning a corner. And those are other places an auto locker feels weird.

An Auto locker is just an interruptible spool....


But whatever, or however it works, it should be transparent in this guy's truck...

Especially since it's so tall and I don't know of a way to lift a truck 7"- 9". So part of me is saying he's got a home made setup.


EDIT: Oh wait, duh... 4" suspension and 3" body.... with a 350/350... :shiver:

yeah 2 inch leaf 2 inch blocks. shes not that scary im not a crazy driver i keep the speeds low and i still have to sway bars so that helps too.

Lockers? Well im a Detroit fan , but if ya get a lock right I here they work very well off road and are very street friendly, if you go with the ever popular Detroit locker if it brakes so do your axles.. but its rare for them to brake in the rear, meanly in the front with hard wheelin I have a Detroit locker in the front axle high pinion Dana 60 with locking hubs in my Jeep crawler and no prob's YET

But as for a Toyota I would go with a Lock Right.

 

[yotacruzer93]

ok thanks for the help

LT1's 275hp, right?

It'll prolly gut a Lock Right with 35's like a fish...

And for some reason about everyone I know has had catastrophic failures with them. And weird as it sounds I hear of way less with a Aussie Locker.

Detroit is ideal, and I cant say the lockrite will be perfect, or the aussie will be perfect. but there are many more people running lock rites out there and thus more broken ones.

Having said that, if aussie had v6 lockers when I was buying my last round of lockers I would have bought theres, despite my flawless lockrites.

im drunk.

im drunk.

Thanks for the warning...

 

[Hilux]

Detroit is ideal,

I agree... They will (easily) handle the power, and I've read they're smoother and don't have as much ill handling as a pocket locker...

I VERY agree with that... I'm afraid he'll split a case, or grenade the locker, or just sheer the teeth of a pocket locker...

dude, 7inch lift, tractor tires, mud, gm drivetrain? just weld it already!

I wonder if the gears have ever been changed? What I did when I got my first mini I called cdan with the vin# in my hand and he gave me the gear ratio.....you might be able to call your dealer and find out.


I have about the lift you got in my 84 and I am running 35's with spools(which I think would benift you in the rear) but I can easily fit 38's without question. If you start putting big meats up front and in the rear you will start breaking s***, more so if you get into the rocks.And you say it has a 350? What protection to you got to protect the axles in the rear...are the they stock? Have you boxed the frame any to avoid frame flex ? Is the front still IFS?

The only(the majority) failures I have ever heard of with Lockrights is the old pins the used to use. I dont hear much about failures anymore....in the 60 section anyway and with the groups I wheel with

i dont rock crawl i live on the eastern shore of md where rocks dont really exist. with that said the only thing i really do with it is mud bog and drive to school i am doing a sas soon i hope. i would rather stay away from spools just cuz its a daily driver but at a last resort that is wat i will do

 

[cruiser88]

Rear spool is no issue as a daily driver. This thing about spools is there is no surprise like with an autolocker. It behaves the same all the time

Do you plan on running ag tires on the highway, at highway speeds? Good luck, I can barely stand to drive a tractor because they are so unbalanced and anti highway. Save some money and 1ton it... If you find the right old guy with an old farm truck you can easily find them for the price of the locker. Weld them up and forget about it.

EDIT= Im part purist, but I can only imagine the pain those 4cyl axles are going through. You could market the rear axle and pay for one of the 1tons. Part out the front end and call it done money wise.
