This is a post that I've just read on the ExploreOz forum. No responses to it yet.

'Can someone help me. A friend of mine bought a new hilux diesel. He has had injectors changed and a new cluth put in prior to 10,000km. On the weekend he got bogged in a small crossing which a ford ute would breeze through. He was not in 4wd as he didn't think it was warranted. At the time he noticed his lsd was not engaging. The wheel which was almost off the ground had all the dive and the other nil. He went to the toyota dealer and was told you have to stop and pull your handbrake on to engage the ls diff. I told him this can't be right so he rang toyota hq. The customer service bloke informed him that in this model you have to pull the handbrake on to engage the diff. I am not kidding, i was there when he rang. He was also told he could not speak to anyone higher and to live with it as this was the way the way it was. I am stunned with this response, any ideas guys?'

I've never heard of it and it sounds somewhat strange. Anyone got any knowledge on this?

I have heard that toyo`s lsd diffs are nothing flash in other posts. Mine is fine tested it in the mud today, but then again I don`t have many k`s on it either

Norm C,

I speak from my experience (as a hardcore offroader since 1994 but stopped in 2001).

We normally use this handbrake trick on Toyota LSD's as they are not as effective as Nissan's when they are old.

But if the vehicle is still relatively new, then the LSD should work without resorting to using the handbrake.

Nevertheless, you have to give the go pedal some blast and let the rear wheels churn before the LSD kicks in if one of the rear wheels are off the ground.

The LSD is and never will match a real locker such as ARB, Detroit or Lock-Right.

My previous rig was a Toyota Bundera shorty and the rear LockRight locker was awesome offroad.

Hope this helps.

My LSD is working fine at 27,000k, other toyota LSD's I have killed early by water in the oil - my bad.

I cant see the hand brake engaging the LSD however the brake can clamp a free spinning wheel and possibly send more drive/power to the wheel with traction, similar to modern electronic traction control but a cheap mans version.

Maybe by slowing the free spinning wheel it allows the LSD to take up ??

I used to jump on the brakes in my old hilux when bogged, hit the go peddle and punch the brake, in low range it helped "sometimes"

iv never heard so much s**t in my life if an LSD is going to work it will work the lux LSD is S**t i got stuck in boggy grass because the lsd wouldnt turn both wheels and mine is under 6 months old not sure why toyota couldnt work out a decent lsd after all this time and the money u spend on the vehicle you would expect this to be a reasonable item i would think but it aint. not sure if its just mine and a couple of them as some have said the lsd in theres works finebut mine is terrible and i tend to really get stuck into it i just think ill have to fork out for the locker!!!

My LSD sucks to. The hand brake thing does kind of work. Put a back wheel in the air and left it in 2 wheel drive. Ute would not move, but pulling on the hand brake would get it going again. not really all that effective though. If you could just apply the hand brake to the side spinning it would work ok. Wish I had a diff lock. wish it was a factory option like the new triton get. only $500 to

my hilux lsd worked the other day when i got boged. my mate nissan d40 lsd is alot better then the hilux thou it kick's out sideway when you put the foot down in the wet in 1st gear. the nissan lsd very tight diff compered to the hilux. nissan has always had the better lsd but that's about all that is better thou 8-)

The rear LSD needs resistance on both rear wheels to work, so if one had little or no resistance (IE nearly off the ground) that this is quite normal for a LSD - for the airborne wheel to spin and the other do nothing. Pulling the handbrake on does not engage the LSD as such, it applies resistance to the wheels with no resistance (the one off the ground) by means of the drum brake and allows some of the energy to be transferred to the other wheel with traction.

What has happened here is not out of the normal. It's only an LSD. It will slip as soon as you get a wheel in the air.

When you engage 4WD and get a front wheel in the air, that will usually spin as well as one rear wheel (whichever has least traction)All Normal.
Hope this helps.

Yeah I agree with Rich. It takes load to engage what is pretty much a clutch between the two wheels. When that load is not there it is pretty much an open diff. That way when you coast around corners and the wheels are rotating at different speeds you're not wearing out tyres or spinning out in the wet. That's how they used to work anyway! I also agree with everyone who says toyota LSD's are shit.

That isnt good i may have to look into a air locker does anyone know how much they are?

by **Doinit** on Mon, 02 Jul 2007 6:55 +0000

What Rich is saying makes perfect sense.
I had two handbrakes (one for each wheel) set up in my old Peugeot for rallycross, gives the same effect "applies resistance to the wheels with no resistance".
I often feathered the brakes whilst accelerating or used the handbrake in my previous '99 4wd Lux to gain traction, haven't had to do it yet in my latest Lux.

found out some info today and yes you do have to use the hand brake.
I also rang a mate how has a diff and gearbox place and he said that like holden you can sim the lsd up to make it tighter with out cost heaps.

I have fitted an ARB AirLocker to mine as the LSD was pretty S**T...The comments above about LSDs needing traction/ resistance on both rear wheels is exactly correct...If I remember correctly it takes about 60ft lbs to break the LSD friction... thats not much...but it needs to be that way so you can drive around corners without scrubbing yout tyres.... Can't remember the exact cost but was about $1600 - 1700...fitted with the bigger compressor... I have to say this thing works a treat... I can now go anywhere my mates go with their "fancy" Patrols with the 6 inch lift and masssive wheel articulation... well except for the ramp overs...LOL but thats another story...Cheers TOMUCH

I've also had a lot of dramas with the standard LSD on my lux.

also had a problem with a pin for the LSD become dislodged and ended up sending fragments through out the diff, cracking the pinion wheel.

Took to toyota and didn't want to know about it. Charged me $500 just to inspect and put back together (Don't go to Melville Toyota!)

Now I have it all fixed with a nice new ARB locker. Driven around for a while now. No problems at all.

What a dream! Bit bad in the wet though with the single spinner!

In my 07 Hilux I have a button for the difflock.
This is not the same as a LSD?

by **9W6VX** on Mon, 09 Jul 2007 6:54 +0000

The diff lock is standard for European models as far am I am aware.

That is much much better than the LSD.

The diff lock will allow your rear axle to function like a normal open diff but when engaged electrically it locks the rear diff to give instant traction at both wheels.

In simple English, even if one of your rear wheels is not touching the ground, the rear diff lock will still give equal traction to both wheels instead of giving traction to the wheel with the least resistance in an open diff.

What you have is similar to the ARB air locker from Australia, Detroit or Lock-Right from USA.

by **X-Cab** on Mon, 09 Jul 2007 7:10 +0000

Yes, I think the diff lock is standard from 2007 here in Norway.

Last year models have LSD.

I was told that the diff lock I got was called E-Locker (100% lock).

Cant believe that overseas models get difflocks and a country like ours so rugged and harsh dont who's to blame!
