So confused now?

[lexulance]

Got to change my hilux to GQ diffs, lexus likes eating toyota hilux diffs, no surprises there!
Looking at getting a swb GQ and either putting the hilux body on the chassis and putting the lexus in that or putting the GQ diffs under the hilux chassis, lots of work in doing that.
I know putting the hilux body on a nissan chassis is gona mean my hilux is now a transvestite!
Atleast with the nissan diffs and suspension under the hilux chassis its still more of a hilux?
But seriously which is probly the better option, i have no idea any more? Any help is good help

Had a look at this one, its far too long to read it and remember it, i lost interest about page 7, too much rambling!

Leave it as it is and learn to drive it accordingly

Getting on and off the gas at the right time is an art, but you learn it.

Just because you have shit loads of Hp, doesn't mean you have to use it ALL, all of the time.

Bit easier than changing your running gear

If you were to change it all over, a better option would be 60 or 70 series Land Cruiser axles.

Ok after reading the above thread im definately going to go for the GQ diffs under my hilux chassis
Hilux diffs are just not going to handle v8 power and torque reliably.
im glad i read that thread from start to finish.

I would go with DBs advice

60 or 70 cruiser diffs will be strong enough for it

and also his advice on driving style too

how many diffs have you blown and why
do you have lockers
do you back off when its in the air


answer these and a whole lot more questions before running off and spending lots of money of gear you may not need

[Fakey]

What skid an diesel boy said is good advice except Im guessing youre still running the hilux g/box an rear diff? The 70 or 60 series cruiser rear housings are offset (diff head to the right of the housing) the patrol rear housing has the diff head in the centre which will line up better with your g/box. Oh an its coil sprung aswell

[lexulance]

Thats exactly why im leaning more towards the GQ diffs because
1: its coil sprung
2: the diff centre in the rear will line up easier with the gearbox

I drive the vehicle very conservatively on the tarseal
When im off road it gets used on some fairly rugged terrain, and im getting to the point where i want more strength out of the driveline.
I have been in the offroad scene for a long time, motorcycle trials, enduros, and other various offroad sports so im no idiot when it comes to knowing what to do in certain situations, if theres grip ill find it if its a challenge ill take it up!!
Heres the deal with my truck, i dont have lockers, when the diffs blow theyre ripping teeth off the pinion,spiders are fine.
its on its second rear diff in 4 months and only on 33s (maxxis mudders ), and yes manual, standard 2.8d clutch,this helps keeping the gearbox in one piece

[nzhunter]

Man thats surprising your blowing diffs, is the lexus standard or has it got a turbo or blower whacked on the side or something?

hilux diffs are pretty frekkin strong, and ive never had a problem even though my trucks putting out a crap load more horse power than a standard lexus.

Is your lux leaf sprung at the front? what gearbox are you running?

just seems like a crapload of work either way, doing a chassis swap will mean obviously having to totally remount the engine again etc,
chucking safari axles under will mean having to make all new spring purches on the axles and chassis also getting all the torque rods right, then the steering issues etc
putting cruiser axles under means having the offset rear diff as fakey said and not lining up with the box

As DB said just drive it accordingly, rollback burnouts on the dry tarseal or big launches arent the best thing for your diff lol but yeah make sure you weigh up all ya options first

[pruggerdore]

I vote gq diffs and suspension on hilux chassis. gq chassis too heavy if you dont need it.

when i had the hilux diffs i ripped teeth of the crown wheels, worked out the average life span of a hilux diff was under 20 minutes of hard use in my trials truck

i seriously contemplated replacing the diff bolts with wing nuts to save time, would get 1-2 trials out of a diff,

there a pajero with a super charged lexus running nissan gear, drives like a complete animal, large jumps, no back off, and i have yet to see the diffs break

GQ chassis isn't much heavier than Hilux. It is a myth that they are heavy.
All of the weight is in the body which is a heavy mother.

It is probably less work to fit Hilux body to GQ chassis.

Yep its running leaf springs, it has a W series box, im told this is a bit rare, and the diffs are 4.8:1, its just a standard lexus with a lot of time spent by me, tuning and then fine tuning, had some very surprising feed back from others that have used my map in thier links aparently its quite good, its only through hours and hours of research an development it has been refined, still working some small bugs out but all good?

[rangimotors]

what are your rear springs like? Do you still have the big flat load springs or have you taken them out?
The only trucks i've come across smashings diffs like that are either running massive power and or tyres or the rear springs have no load leaves and no tramp bar causing the axle to twist and drive the diff on a funny angle and smashing teeth off.

[turoa]

Im not suprised about diffs being smashed. Its not hard on a lux diff

go the patrol susp under the lux. Whoever said body swaps were easier cant have done it. Redoing all the brakelines, fuel lines, body mounts, steering fuel tank etc etc etc is much more work than welding a few susp mounts under a hilux chassis.

It might be more work to put suspension under a chassis than to weld on some body mounts, but it is all the other work that has to be done that has to be thought about

It still has the overload spring in both sides of the rear, i did have an anti tramp bar on it but it cracked the chassis cross brace three times, and not only but also it blew the diff within about 1.5 months of fitting it, the tramp bar had a rubber bush on the diff end and a rose joint on the cross brace end, so wasnt solid mounted, took the tramp bar off and fingers crossed the diff has held together for a bit over 2 months now

[Heath]

I'm picking the thickness of the teeth on the 4.8's are less then the 4.6 diffs. Maybe its just an inherent design flaw with the lux diffs so the bigger solid nissan ones would be better. Of course you then have to contend with huge lumps of steel hanging down between the wheels "grading the track" so taller tyres will help, which will mean higher ratio diffs (getting thinner again) which potentially will lead to breakages in the more expensive nissan diffs. Sometimes you just cant win.

Maybe difflocks would be better, letting you attack stuff more slowly and thus putting less shock load on the drivetrain parts.

Of course that's just my opinion and its worth exactly what some wone is willing to pay for it - zip!

Good luck.

[philux]

I know of a fella down here in chch that has done a gq axle swap in a ifs surf. 5 link in the front and a 3link plus panhard in the rear it has got pretty good flex and reliability, but for the amount it costed to get some one to do it you could probably buy 5-600 hilux diffs, why not look onto chrome molly axles and hubs, and a couple of lokka's. Id stay away from it unless was for competition use or very serious 4wding.

[Bulletproof]

The Nissan diffs won't cure your problem.

Nissan CVs are very weak and will give as much trouble as you have now.

Kyle in the top of the south winch Challenge blew 2 CVs and a diff a couple of weekends ago in his V8 nissan

I hear what your saying, the problem i have with lockers is trying to find some for a reasonable price, as my budget is not huge, all i really want is a good reliable drive line that i dont have to worry about destroying when things get tough.
I would like to be able to attack things a bit slower than i have to at the moment, that would be very helpful on undulating uphills with a bit of cross axle action?

[philux]

keep your eye out for lokka's i managed to pick up an auto lokka in a diff for 350 depends if you want arb/chinese imitation one etc. other thing to consider would be the gear of the nissan most likely being 4.1 to change ratio could be up to 2k for bringing in aftermarket ring and pinions then setting them up, then what do do about the handbrake etc. Hence the reason iv now got my nissan diffs up for sale, twin locked and a winch has gotten me everywhere iv wanted to go, with change in my pocket. Just my 2c

[meatc]

Have you tried after market 4.88s? they are apparently stronger. Also I believe that some of the later v6 4.88 (hens teeth) are a thicker ring due to the failure thing.

Also who is setting your diffs up? Could be a lack of preload? causing the pinion to run on to smaller section of crownwheel tooth?

The lux weakness tends to be CVs not centres.

[Landy Rover]

Something to add, a lokka is only replacing the side gears, and plates with springs and rollers. If its an open diff, two spider, then lokkas arnt going to make it any stronger. Under severe shock loads the open diff carrier will flex and cause the ring and pinion teeth failure. ARB carriers are a solid unit with four pin spiders. Therefore next to no flex in the centre, keeping the ring and pinion in proper mesh. Having said that, theres only so much load any ring and pinion can stand, but having a locker there isnt the need to drive it so hard. Well worth saving the pennys for one! My two bobs worth

shouldnt atleast 1 locker be an option regardless of what your going to do considering you say you do some pretty tough stuff.....
fit a auto locker $600 then go from there.

Interesting. I have both and qq sure looks heavier chassis, but Im sure you know safaris a bit more intimatly than me.

I just cut up a gq chassis for its suspension mounts diffs etc they are way heavier than any hilux Ive seen sure the body is a heavy tank too but the chassis is full box section an very heavy even when in small pieces

[wopass]

i say just flick the lot off for scrap and buy a lada.

Just so happens that im thinking very seriously about some ARB air lockers have priced some from a place in chch
diff centre, $1250 + Gst
compressor, $350 + Gst, (this is the bigger one,good for tyres aswell)
These are trade prices, are they good prices or can you get better deals than this??

It is a big section but the inner of the rails is less than 2mm thick! Sure they are heavier but it isn't very much. When mine was apart then 2 of us can easily move the chassis around. I could turn it over etc by myself as well.
Lets put it this way, a GQ front diff is heavier than the chassis!!!!!!!!!!!!!!!
