Tuff-Trol

Iam currently looking at an 2002 Toyota Landcruiser HZJ 105R from a yard in town .

I have heard lots of horror stories about them from having Hilux diffs , to being buckets of poo ..... knowing how stories are perpetuated i would like to hear some good hard facts and for's and againsts please ....

The vynal interior is a huge bonus as is the interior space .

Also are they live axles or the dreded IFS ??

Many thanx in advance
Brad

Hey Tuff trol

I own 3 100 series, so let me help you.

Myth 1 Toyota diffs are out of a hilux: the rear diff is the same as the 75 80 78 79 100 series, The front diff is the same as a hilux rear diff.

Myth 2 100 series gearboxes are crap : well I have 1 thats done 77000 km, one thats done 250000 km and 1 thats done 290000 km, all the gearboxes are fine, any problems that could arise would be driver related.

The one you talk of is the 6 seater STD one, if it has vinyl seats, I have a 2000 model STD thats the one thats done 250000 km, the only problem I've had was a noisy rear diff and I fixed it for under $600.

There a tuff truck in the right hands.

Cheers Steve.

I just spoke to a mechanic, who was the lead mechanic at a Toyota Dealer for 15 years.

He told me the rear Hilux diff and the front 100 series diff were slightly different but defied a man off the street to tell the difference.

He also said the rear 100 series diff has only changed slightly since 1975, the difference now was the since the 75 series, it is now LSD and the bell shape has changed but still bolts up to the housing.

My memory might fail me but i think the hilux has a low cut pinion (IE the tailshaft ataches below the centre line wheras the 105/75 ataches above
- any man on the street would notice that
(and no you cant just put a diff in upside down)

well most diffs work the same how much difference do you want - certainly the crown wheels are a different size.
Id say is a huge difference if you can chuck one into another (mountings aside) and have it work!

Go to this site and look up Part # 41201 29526 Hilux 4.3:1 crown wheel and pinion.

then scroll down to find Part # 41201 80135 L/Cruiser front 78/79 100, 4.3:1 crown wheel and pinion.

Then explain the difference in size you were talking about please.

corse they dont look significantly differnt - they do the same job
However the link shoots you in the foot as it clearly demonstrates the parts are different or they would be common to hilux and cruiser which YOUR link clearly shows they are NOT!

The crown wheels are the same diameter and have the same amount of teeth on the spline, the only difference is one bolts onto a center designed to fit a Hilux diff housing, the other bolts onto a center designed to fit a cruiser cruiser housing.

So as I said in my post today, they are slightly different, If you put the diff centers on a work bench and asked a man off the street to tell them apart, chances are they couldn't.

The diff centers are the same, the only difference is the way they bolt into the housings eg: 1 is a Hilux and the other is a Cruiser, which would account for the different part #s.

And in addition Steve the part number for an ARB diff lock to fit either the Hilux or 100 series front are the same indicating the centre at least is the same small diameter.

Brad the 105 indicates its a solid axle. (100 is IFS) No the diff is not out of a Hilux but is similar in size & yes plenty of issues with them breaking. I've blown 4 but I drive in rougher terrain than most. They certainly have had their fair share of issues with recalls on the cable tyre winder & recently the front brakes. Ignition locks are now starting to fail as well on a regular basis according to my local Locksmith. The diesel motor is pretty dated but does everything asked of it. Many have problems with clutch shudder (particually when cold) & despite getting replacements they tend to reoccur. With careful engagement it can be minimised & one soon lives with it.
Of it's age you would be hard pressed to find a more comfortable, spacious good handling 4by in it's class. The gears are well matched to the motor & has a well set out dash making it a pleasure to drive. Has a very good low range 1st gear making steep climbs & decents easy. It's fair for towing. Cracking issues (body/cassis) like found in the 80 series don't seem to be an problem in the 105.
Cheers Craig.........

What was he doing in 4wd reversing up a driveway?
Any way they are the same diff as in the dozens of utes we use underground each of which does more reversing in a day than alot would do in a lifetime including reversing up declines etc so they cant be that weak in stock configuratio. Going by your comment we would be doing 2 or 3 a shift

Using low range to maneuver his camper into the shed. He has a fairly steep, tight driveway. Steering was pointed straight ahead when the diff went bang.

This is the only first hand experience I have of the issue and I was amazed at how easily it went.

Hey Brad,

Good vehicle, look after it, treat it with respect and you won't look back or have troubles with it.

I'm on my second.

I have the GXL model and have broken 2 front diffs - both replaced under warranty. The issue is SHOCK LOAD. The first time it broke teeth off the crown and pinion was in my back paddock when trying to reverse out of a bog (don't release the clutch too quickly). The second time I was snatching a mate out of a 3 foot deep rut, up hill, in his GU (Don't even ask why he thought he could drive through it) but my front wheel left the ground spinning and when it hit the solid ground again, bang - teeth off the crown and amazed the strap didn't break. I have now learn't how to drive my 105. Every car has it's Achillis heel and this is the 105's.

Don't let this put you off though as I love my 4bee so much so that it's probably not healthy...

Lockers no doubt would help this issue as there is less need to use momentum. Now I know it's limits, why swap to something with different issues, as envrything has something to complain about.

And, as I said I have an unhealthy love for this vehicle. I've also owned a 40 series, a 60 series and a Pajero before.

Cheers,
Chris

Well done Chris,

I think this is the first time I have seen someone across a range of 4WD sites say that it may have been driver influenced damage!

It seems to be agreed that an ARB diff lock can improve the strength of the factory diff due to a stronger carrier design which limits flex in the diff. I have them now, but didn't in the first 100 and both have worked faultlessly.

Can you love the 4bee too much?

Ross.

I'm doing my wheel bearings tomorrow on a 100 series, I have a 78/79 rear axle.

I am certain It will fit, but to be sure I will put it in and try it, I will put them together and double check.

Hey Ross

The 100 series passenger side axle is longer than the 78/79 series by about 3 cm.

So I would say thats a no.

I knew it would be longer but we needed to know if the splines and axle diameter were the same.
The diff is going into a 79 series and he needs an axle for it.
These models are very rare in North America

There the same spline and diameter but mine is a 105 diesel, because there the same diff center.

But I think you are talking about a petrol model, I can't see that they would be different, as the gearing is the crown wheel and pinion not the center it self.

Hope this helps.
