Diff locks

Post by kiwinoz »

Hey guys, I was wondering what sort of diff locks you all might have.
I have none, not even LSD.
Seems rather costly to go airlockers along with compressor and all.
Does anyone have an LSD front diff?
What ratios do you have with the td27?
Most ppl over here are only interested in Patrols/Cruisers

Thanks guys

TD 27's have 2 main ratios;

4.625= 37 ring gear teeth + 8 pinion teeth.
4.875= 39 ring gear teeth + 8 pinion teeth.

VG 30's

4.375= 35 ring gear teeth + 8 pinion teeth.

Front diffs is a whole new subject. i think the fronts of the D21's are R180 in their own housing.

Cheers,
I keep looking for the loose nut behind the wheel, but I can't find it!!

Interesting, STI WRX's use R180 LSD rear diffs. I wonder if this could be another alternative to fitting an LSD in the front. Ratio's are funny, 3.9:1 so might just be able to swap the centre's around.

I had an "open diff" in my '95 Terrano and acquired a LSD from another truck. Swapping the open for the LSD was easy and we just swapped the ring rears over to keep my ratios the same. I have not bothered with the added expense of going to a locker and may look at a LSD for the front one day, but it is not on the priority list of "to do's" :wink:

I suggest looking for a LSD for the rear and seeing how that suits your needs first.
Ok people, move along. Nothing to see here. Thank you, move along.

Hehe, thats not because of the LSD... :wink:


But yea, Lsd in back helps alot. Just dont expect it to keep you going when cross-axled, you need a locker for that

I have a LSD in the front of my MK Safari (C200 front diff), got a LSD from a Navara swapped the crown wheel from my truck and put back together. Front LSD a bit stuffed so doesn't limit slip as well as hoped - however sledges a bit when turning in 4wd so glad it isn't anymore aggressive.

Na it mostly was that mine was lsd and his wasnt, his was a 1kzte surf, when he hit a hill and it flexed abit, one wheel would spin and that was it, then the terrano would just crawl up it no worries.

I was just taking a lil dig a toyota :lol: But yea, lsd does help alot going over rough terrain when not quite crossaxled. Then a locker is what you want :D

charo249- Do you have locker in rear? Or if lsd, how tight? Just interested to know about how it makes it handle in regard to tight turning, particuarly in slippery conditions with front lsd?

Hey.

If you have an open diff in your truck, you are half way there to a cheap option for a locker.

You can get a Lockright Auto locker to fit the rear diff for your model truck.

You need an open diff carrier to fit it into.

It should set you back around the $600 mark. Install your self. No compressor or air lines or seals etc etc to go wrong.

Because your truck is IFS, if you just buy one locker, make sure you put the locker in the rear.

Don't waste your time with a factory LSD, they are designed for driving on icy roads in Japan, and that's all. With a break away torque of 60nm (thats for a Nissan, Toyota LSD's are 40nm) they are essentially useless off road, despite what people claim on here from time to time.

The idea behind the factory LSD is that if you have one wheel on ice and the other on something that supplied traction, the LSD will apply a tiny tiny tiny amount of torque (60nm) to the wheel that's got traction i.e not on the ice, and allow the truck to creep forward.

Go for an auto locker in the rear, best value for $$$$$$

Have a standard LSD in the rear as well - as I said sledges a little when turning in 4wd especially if it is a little greasy. Truck is a SWB so still reasonably maneuverable, but could see it being a real pig if you had a real tight LSD in the front diff.

I really dont understand how you say the LSD's are useless, Going from open diff to LSD i noticed a huge difference... Obviously a locker is going to be alot better, but you can pickup terrano LSD's for $150 so if your on a budget, its definitly worth it.

Jack one of the rear wheels off the ground and try and rotate it.

The resistance you feel as you try and rotate the wheel is the break away torque.

So to put it simply, the force you are applying to turn the wheel that you have jacked off the ground, is exactly the same amount of force that the LSD woulds supply to one of the wheels in an uneven traction scenario.

Try jacking one rear wheel off the ground and rotating it, you don't have to supply much force to over come the grip of the clutch pack, you will see what I mean!!!!!

My "opinion" is that for the work required to fit a LSD, brakes off, axles out, drive shaft off, diff head out, then all back together with new seals gaskets, bleeding the brakes, adjusting the handbrake etc etc, its much more sense to fit an auto locker which is actually going to have a noticeable difference to where you can drive. That is coming from my personal experience with having had a Terrano with a LSD, a Surf with a LSD, a LWB Vitara with a LSD, a Safari with a LSD and then an auto locker, a LJ50 with a rear auto locker, a V8 Jeep with a rear auto locker, an 80 series cruiser with a rear auto locker, a SJ413 with a rear auto locker, a SJ413 with twin ARB Air Lockers, a Range rover with open diffs and a Defender with open Diffs.

Fark I've got through some trucks eh :lol: :lol: :lol: :lol: :lol:

You don't have to agree with me, in fact its much more fun if you don't, but I think my opinion might carry a tiny bit of weight though???

Check this out of you have any doubts still??

This is the best!!!!

You paid good money for a LSD so of course it is better!!! :mrgreen:

Unless you have an LSD which has been shimmed up then they are not much improvement.

I had a factory Paj LSD (one of the best ones) and went to a locker (massive difference). Then broke all the teeth off the locker so had an open diff. I was impressed with the open diff I gotta say! So impressed, I thought whats the point of LSD's!!!

I have gone places now with the diff locks and think you'd never get up there without them, so go for another try but quite often you couldn't be more wrong! Its all in the mind.

I've got front and rear diff locks in both my trucks and I still get stuck heaps so dont think they are the be all and end all, they are a usefull tool in the right applications but they can also get you further into the shit and make it harder to get yourself out, you can end up with all 4 wheels digging you down onto your belly instead of 2, you can lose all control of which direction the truck is going to go in if your in slippery shit or on hills without wheel ruts to guide you, unless you've got longfields or chromemolys you can end up becoming an expert at swapping out broken cv's and the worce thing is other pricks with better trucks and open diffs still manage to outdrive your chevy 4 wheel locked cruiser :x .... its all horses for courses :mrgreen:

like a 413 zuk in the slippery forest??? :lol: granted it was a weldrite rear thou!

but like Sadam says, with more traction leads to getting more stuck, sometimes thats a good thing other times not.
im with Pete thou, in your situation if the diff has to come out once do an auto locker on your budget :)

Haha, the truck with locker hit it at such a speed, even a front wheel drive open diff car woulda made it... but obviously in a situation like that a locker would win, as one surface is grippy as fark, as it would in most areas, but i would still have an LSD due to the cheapness of them, and as others have said, lockers put a shit load more strain on things, especially when you lift a wheel and drop it down again with some speed.

Just to chuck a spanner in the works, how many guys use there brakes when cross axled? I was playing around today on a big rock picking up two wheels and then going no where, I just started applying the foot brake (left foot) at the same time as giving it a bit of gas and I damn well climbed the rock with two wheels a foot in the air. Maybe brutal on the brakes but might get you out of the shit.

its called left foot braking do it regular my self but im getting lazy now with arbs front and back

its a lot easier with an auto but still posible with a manuel box and its a handy peice of knowledge to have when on slidlings etc

Unless you have some sort of semi reasonable LSD then how can this work.....

Either you were going to spin both wheels anyway or your brake balance isn't spot on :wink:

Used to work in the paddock in a front wheel drive car when conditions were slippery and it was only spinning one but crossaxled..... nup!

Definitly works, the more brake pressure you apply the more friction, eventually the spinning wheel will have as much friction as the non spinner, and they swap
