After taking the the Troopy into the mechanics today, the bloke took it for a drive with me to listen to the noise in the gear box. He rekons it is coming from a bearing that is on the shaft that is on the bottom of the gearbox....I just can't remember what its called. Any way he rekons to fix it will be about $1700 min and up to $2500 max to fix! They have to send off the shaft to Brisbane and have it hardened and machined then a new bearing fitted.....if thats the only problem! If anyone has any thoughts or coments or knows what a new gearbox would cost it would be appreciated.
Also thanks to all those fellas who helped ouy with my questions on the drawers for my troopy and for the suspension ideas.

As a Mechanic (8 years with Toyota) you can not just go for a drive and diagnos a counter
shaft fault like that. It might well be that of just a normal roller bring worn!!!. you have to pull it down and have a good look and proper diagnos of the fault, Bewere!!! the cost might get big. ie. how are the syncros rings, gears mmmmmmm not sure!!

Ouch! Id be getting a second opinion.Sounds like he has left the quote open to how much he's made for the month.Really hard to diagnose G/box probs just by driving.Glad I have a GQ strong box.I'm sure you can get a recond box with warranty for the about the same price.Not much help but is the noise a $2500.00 problem?

Hi matt,
yeah your right you can't drive something and diagnose the problem, he said that but its what he thinks it could be. They have to take it out and have a good look. Yeah its not cheap but he said it would'n be more that $2500, those words hit hard as we are saving for our round oz trip, but better get it sorted now than half way between Cooktown and Cape York.
Thanks for the reply

Hi Bluey 221

Is it a 75 or 78 series I am more than familiar with both and their problems.

Cheers Steve.

A couple of years ago we had a strange noise that developed driving back from the Gorge at Mornington Station off the Gibb River Rd.

Got into Kununarra (slowly I might add) and 3 workshops including the RAC said it was the gearbox. The RAC wanted to pull it out and send it to Darwin for repairs.

The 4th was the ARB dealer in town who said it sounded like the gearbox but we'll have a look at the Diff (rear) first. Lo and behold 4 hours later the diff was fixed and no more noise. (ARB in Perth did something wrong when they fitted the Air locker). ARB Kununarra told ARB in Perth they were paying. I was relieved I can tell you.

So, the moral is check other sources of the noise before committing to a gearbox overhaul.

I had a noise once too, when standing at the left sidr it sounded like it was coming from the clutch area, turned out to be the Alternator. Had the mechanic stuffed for a while until he got the stethoscope out

I don't dispute your story for one minute becaue I've witnessed such incompetence first hand, but if a 'mechanic' can't pick the difference between a diff prob and a gearbox prob, I'd sack him on the spot or alternatively, get him a job as a stand up comedian!!

Sheesh!! What do they teach apprentices these days hmmm !!!

BTW Bluey, the shaft in question is the layshaft or if you like "American", it's called the countershaft.

Usually, if the layshft bearings are "groaning", the rest of the gearbox won't be in too good a shape either. It's prolly more cost effective to get a recond box and avoid all the messing about and uncertainty of "guessing" what to replace in it.

Bilbo could be right ,but some of these exchange reconned boxes are an unknown quantity.
I was in this predicament 6 months ago and I opted to have mine rebuilt
I got someone to remove and disassmble it and went over it with him and agreed on the parts needed.
It was about $2300 with the t/case bearing done as well and installed with oil.
Ive done 15000klms since and it was money well spent ,its loosened up a little and shifts nice(as well as a H55f can;) )

The RAC bloke wasn't young, and I drove around for a kilometre with him hanging out the passenger door, ear to ground so to speak.

I've got to admit that I was surprised that a noise from the rear could sound like it came from the front.

337,000km now and no gearbox problems at all. I have Redline oil in it and it changes very smoothly. The diff has been OK too since the fix up.

Hi everyone, thanks for your advice on the gear box issues. Bilbo yeah your right thats what the mechanic said "the lay shaft" he rekons the bearings at the end go in them and they wouldn't know what elae it needs until it is pulled apart. I may as well get a new gearbox if its going to cost $2500. I just saw on the internet that landcruiser mart has them reco for about $2 grand.
The noise is definatly coming from the gear box as you can change the noise by moving the gear stick while driving along.
The mechanic also said i should run good synthetic oil in it too.
Thanks again
