Hi all, haven't done this mod yet as I'm still looking for info. Has anyone come accross a Detroit auto locker that is available for the 1989 model LWB Bighorn, am looking particularly for one for the front at the moment. If I can't come up with a detroit one to fit will have to look in to the Lockrite, as I know they make those but are generally more expensive from what I've heard.
Any info on what you've got fitted and how it goes appreciated.
Garth

detroite is a brand of locker but I dont know if they made one for the isuzu If looking on the web be carefull as the US isuzus got Dana diffs not Isuzu.
The lockright and Locka brands are virtualy identical

Re lockers - I have also been trying to source them from USA but with no success. Only place I know that makes/supplies them direct is in Adelaide. The website there is www.4wdsysyems.com.au/. Some vehicles I know use them and they are very effective on front or rear. Have sent them emails without reply, but if perhaps our Aus members could enquire there, we might be able to get a club price for front or rear Lokkas(their trade name - evidently a copy of US Lockrite) for the mu and bighorn. Be very interested to hear the prices - Mike A. |

I have one in the front diff of my MU, cost me $660 inc freight about 18 months ago. Matt tried to get one recently and was quoted around the $700 mark and they were not very receptive to the request for a discount. The best thing is to ring them direct and and maybe go in with a price for multiples. J

Latest price for the lokka (front - don't know if there's a difference for rear) for a prospective member is $545 Aus freighted to NZ, which is about NZ$615 at the moment with favourable exchange rate. Single purchase.
A question - how does your front lokka effect steering in 4wd Justin? Have heard any front lockers can make steering a bit unpredictable. What effects have you noticed off road low range, and also in high ratio 4wd with a few k's on? Rear lokkas will have much less handling effect I think - just apparently a few clicks when cornering on road? Regards Mike A.

I belive the locka dif lock is only one size which fits the rear diff on 87 - 91 bighorn or front for later bighorns and mus
the front diff on the later bighorns has the same internals as the earlier bighorns rear diff

It was only available as a front locker for the MU, so I believe what Alan says is right. It does affect the steering being quite grabby when coming out of a corner but certainly doesn't reduce the manoverability of the truck. It also does disengage when turning a tight corner at low speed. I have match my MU against others and the traction gain is very good especially with the combination of a LSD at the back. J

The diff should be the same as the newer jackaroo/bighorn/trooper from 88 to 97 Have a look at the ARB locker application gide www.arb.com.au/alac/215109.pdf |

Single purchase. Mudgrip, do you have any more details of your research?? Who where how much and is that only because of GST exept etc!! Im looking for my front locker, have for ages and the best and really the only suppliers I got are 4WDsystems and its about $700 all up for the LOKKA. Is that who you went through and if so who did you speak to, Im very interested and ready to buy if the price is what you quoted!! Thanks Mate! Matt. |

A member of the Christchurch landrover club and prospective Clubisuzu man is right now buying a Lokka from 4wd Systems Adelaide for his Isuzu and the price they have agreed is Aus$545 - about NZ $615 delivered. Unsure about GST but it could be factor.
Called 4wd Systems myself 2-3 days ago and got very vague answer. Bloke said $695, then $630, then $600Aus. Then when I mentioned the $545 price, he said "yeah, we might do that". This appears a problem with this outfit - remember others commenting on it. The deal can change markedly depending on who you get on the phone - and they don't answer emails or faxes.
Best thing would be to ring and ask for the sales manager and ask for a club price, mentioning the $545 already quoted. Tell him there are others interested in a good deal and then post the results. Their phone no is 0061 8836 90033. Meantime I'll try to find out about the GST bit. Hope you have more luck than I did - Mike A.

Hi all, thanks heaps for the info. I have contacted a couple of 4wd shops here in auckland and got very vague answers as to availability of diff locks for an Isuzu. They didn't seem all that interested other than ARB.
If I could get one from ausie for around the $600 to $700 mark that would be great. If anyone is thinking of ordering one can you let me know.
my bighorn is a 1989 LWB Irmsher R, and I think it has the same front diff as the Mu's from what I have heard.

You should definitely be able to get one at that price, I believe Matt was after one too so you should both be able to squeeze a decent price from them. J

Jimmy, Do you have a LSD? I have a mate with a 3.0lt hi-lux with a rear locker & my MU with out the LSD tag under the bonnet but it goes every where his truck goes. More toy's on the truck does not get you to the top of the hill every time. Check for the LSD  Dave |

Hi Dave,
No Mine does not have the LSD.
Justin pointed the G80 option out to me but unforntunately it does not.
Traction is an issue for me. As discovered on some recent hill climbs.
Having two wheels spinning while the ones with traction are still defeats the purpose of 4WD to me.
As my MU is only used for 4WD trips traction is important to me.
I hear you are looking into a traction control system of some description? How is that going?
Modifying the beast is all good fun.
I look forward to seeing your setup.
Jimmy.

The reason i asked was i do not have the G80 & have a good LSD also Bruce does not have the G80 but also has the slipery. He did not think he had one untill we had him at LCMP & it showed its head to his delight.
We will have to catch up after TTC & take you for a run on some of our local tracks. After i get over the cost of the new radiator & thermo will be getting the traction control installed that could be in about a month. ;D ;D ;D

Sounds good.
What do I look for if not the G80?
Does the housing look different or is there some physical difference to look for?
Maybe I just chuck her in some mud and let it rip? See What spins and what doesnt ;D

Jack up the rear axle to clear both wheels off the ground.
With handbrake off, spin one wheel, if the other wheel goes the other way it's an open diff (or a stuffed slippy diff) If they go the same way is likely to be a slippy diff.

Thanks for that. I will see what happens this afternoon.
I am chasing up some different options for locking at the moment.
I have been asked for the GVM & number of axle splines & o/d of spline for the MU.
I think the GVM (Gross Vehicle Mass?) if that is what they are asking for is about 1780kg...
I have no idea about the diff stuff.
Can anyone help me here?
Jimmy.
