I'm looking seriously at buying a Cruiser with only 111,000 Klms on the clock, it's 2004 but I read somewhere that the gearboxes are a bit light on. Can anyone fill me in please.

Old Dog
yes they are a light duty box.
I have an 04 HZJ105R and tow a Trak Shak camper BUT never in 5th.

Treat it nice, don't lug it, i.e. change down early and it should give you years of service. Mines done just on 200,000km.

If you want to tow a 3 tonne caravan maybe join LCOOL and look at how to do the conversion from the R151 box to the H150 box.

Oh, the factory turbo diesel and the petrol 100/105's have the heavier box. Seems the !HZzzzzzzz doesn't have enough power to need the stronger box...in normal use.

Have fun

Hope not

First one is rebuilding the r151 with stronger internals
Second is what is needed to put a H151F into HZJ105R

G'day grumpy (first name basis) I love your philosophy I wish I had thought of this before you:
Life is short, Break the rules, Forgive quickly, Kiss slowly, Love truly,
Laugh uncontrollably, And never regret anything that made you smile.

Dude I want to meet you, anyone who truly thinks this way and hopefully lives life the same way is someone I'd truly like to spend some time with.
What do you reckon?

Old Dog, a meet is on the cards. I just have to get over a medical hiccough first though. When the Doc gives the all clear we'll be off again. Usually live and work at Blackstone, W.A. About 95km west of Surveyor Generals Corner, but had to move closer to the R.A.H. Hopefully not for long, too many folk in these cities. And more white folk than I've seen in a while!

Oh, an extra thought on the HZJ105, don't ever give her a hard time in reverse and 4WD.....weak front diff!

Mate, I was looking at a 100 series but ended up buy a troopy, 20001, it's a 70 series, and yes it has the weak gearbox (so I've discovered) but we (the misses and I) fell in love with it and now we own it. I will have to be a little kind to her in all gears but I'm not that hard on anything (period). Dude are you going to make it? Things don't sound fantastic? I'll be praying for you (if that's ok with you)

G'day Grumpy, haven't heard how things are for you mate; hope the doc has given you the green light or is about too. I've ended uo with a Troopy. She's 2001 HZJ78R; she's got the weak box too, can't seem to get away from it, same rules apply and now I have got the good oil on what happens and what the fix is I'm fairly happy. If things go pear shaped it's not that expensive or difficult to fix. Anyway I hope to be seeing you sometime in the not to distant future.

Mate, I have the hzj105 with this box and it's the original, done 280,000 now and still good, 1hz has a turbo on it and I tow a 2 t van, before me it used to tow a drill rig trailer. I don't tow in 5th gear from advice and no dramas so far. I look after my car and if you do the same I don't see how you can go wrong, go for it their a good car

Thanks jacent, sounds like the advise about NOT towing in 5th is good stuff, I'll try and remember. I too will be looking after my vehicle and therefore feel similarly to you; take care of it and it will take care of you. Thanks mate, these comments really puts a blokes mind at ease. Hope to see you out there.

You are right in that they have a light duty gearbox, but as GOF said, treat it with respect and it should be fine. The other issue with both live axle and IFS 100's is the weak front diff. The crown wheel gears are cut to give strength forward but not in reverse, so don't go mad backwards recovering or snatching. Even so they can break going up a hill if one front wheel loses grip and spins up. I have put in an airlocker in the front as this reduces the possibility of damage.

Thanks Mike, I hope I don't go mad period, either forwards or reverse. but I hear you and thank you for your comments. Sounds like they"ll do the job as long as I treat it like my misses; with respect; she's small but she can punch.

Hi Old Dog,

I bought an 03 about 6 months ago and it had done bang on 150,000 kms. I too had heard the scare mongering about weak gear boxes and weak diff but 10,000 kms later I have not once had any issues and let me tell you I have put it through it's paces. A bit slow on the highway (I don't tow anything) but if you change down into 4th early when overtaking and never plant your foot and try to overtake in 5th you should be fine. Out in the bush and on the tracks, up the dunes, through the rivers and along the beaches is why I bought my Cruiser and in that environment is where it performs at its best and in its element. If you do mostly hwy driving I would consider something with a bit more get up and go. Good Luck!

G'day Craig, I like the way you think, I don't expect to get old if what you say is true, I'm into "playing". Thanks for your comments on the 100, I'll be towing a Trackmaster Gibson, but I'll be in no hurry to get anywhere. The highway is just a means to an end or maybe a new beginning, bush, tracks, dunes, rivers and beaches are where we're heading. We are so sick of the daily grind of eat, sleep and work that we can't wait to be able to get out of the rat race and get back to basics. Thart's why I'm asking the question, we don't want to be stuck in the middle of nowhere with a busted gearbox or diff and have to use all of our funds to get repaired. Sounds like the 100 series will do the job as long as I respect her, and treat her well. I used to own a Ducati motor in my younger days and I always tell people who are thinking of buying one that "Treat it like your woman, spend time with it and do right by it otherwise it'll destroy you". Maybe good advice for this 100 series.

G'day old dog! I hear ya. I guess I'm still a young'un at 38 though my 16 year old nieces treat me like an old fart! I lived in the Uk for 7 years and travelled extensively and although it was a great experience I now love nothing more than getting away from the daily grind that you speak of. I love my surfing, photography and exploring and they all go nicely hand in hand with owning a 4WD. My lady and I always say that you should always have something to look forward to, it makes the rat race that much more bearable and we are always planning our next trip. In fact as I type this we are getting ready for a trip down the south coast of WA tomorrow afternoon for a few days. I like your analogy! Good luck with the fourby hunting and hope you have many memorable journeys in it with no dramas.

Cheers

Craig

I was saving up for a 900 super sport which then cost $5700 brand new when Ducati bought out the Darmah, it was Desmo with all Jap electrics and brand new was $2750. I got the black and gold model, this was back in 1982. If only I had her now. I'm not unhappy with what I did; I traded it in on a 750/6 BMW, I put 485,000k on that old girl, still got her but now I ride a 1000 RT Classic, got to have a big fairing in Tassie when it's -2 at 6am in the morning when I leave for work.
Do you ride mate?

No i don't ride any more . Marrage and kids slow some things down and then other interests take over. I still have a Ducati 350 ss 6 day trials bike that i purchased new in 1969 . I think it was $708.00 . Not much you can buy new for that much now days. The old 4x4 sort of takes my interest these days because the grand kids can come as well. Be nice to meet you one day.The next time i come to visit my old school mate in Hobart i will put you on the list . Enjoy the bike Old Dog......

Ours is a standard 1Hz Troopy with pop-top camper weighing around 3 tons. We have just got a recon gearbox after 260,000km.

The crunch came when our local Toyota dealer drained the oil but did not put many back in. We did 3000km like that before it started jumping out of gear.

And no, the Toyota dealer did NOT admit liability as it was me that found the lack of oil, not him????

If it were not for the Toyota dealer, we would still hav a good gearbox for who knows how long, but we do not tow anything heavier than a 12ft tinny.

G'day Steve, it's so typical that no one admits liability, what did the box cost you?
I ask because I have only yesterday bought a Troopie; ours is a 2001 HZJ78R and on this forum in another thread it's been said that the box has been known to be troublesome in this model.
I still need to check out the compliance plate to see what transmission I have. Trouble is, the misses loves it, I love it, it feels great, it drives great; but I don't want to put my head in the sand and get ourselves into trouble exactly when you don't need it (Murphy's law and all that)
I want to put some miles on it and get used to it before we head off into the wild blue yonder and if it needs a box down the track I want to be prepared.
