How does one know when the clutch is buggered?

For a simple test, although it will / may use up what’s left, is to:

1. apply the handbrake firmly
2. select high range only
3. select 3rd gear
4. do the toe and heel trick – toe on the foot brake and the heel on the accelerator
5. rev it and then let out the clutch
6. if it keeps revving with the clutch all the way out – Good night Irene on the clutch
7. if it stalls with the moderate revs applied there is some limited life yet
8. if you’re really concerned – just replace it with a heavy duty one. Also a good time the machine the flywheel and replace the rear main seal.

PS: not to be used as a weekly test, only if you think there's a problem or when buying a vehicle.

Having clutch issues with my 80 series, it shutters when fully loaded. Get a pro to check it out, and then get a second and third opinion, l was told by one mob it would not last my next trip, but fortunatly l have a mate who is a toyota mechanic and he took it for a drive and said l should get at least 50000k's out of it.

I got 259 000 k out of mine and it wasn't worn out, only the dampers gone causing extremely loud rattling. Put an after market Daiken brand in and noise got worse. Replaced it with a genuine toyota one and presto no dramas.
Mine is a diesel though.

Gidday,While you are under the 4by check all your engine mounts.Not just look but get a wrecking bar and lever the mounts apart.You will soon see a broken mount and these can also cause a shudder in the drive line.

When your car fails to move forward with engine running and car in gear, she is fubar...

Good one Truxta!
I wouldnt do any of these...if it is going to slip, it will do it in 5th up a big hill.
You should get heaps of warning with the clutch, and it shouldnt have slipped in low range...more probable the oil come out the power steer reservoir and onto the exhaust...

ps if u go into toyota, they will sell you a t/d clutch as a 1fz replacement...as they are thesame size, but heavier on the foot....Apparently Toyota get their clutches fropm Daykin. (and make toyotas out of them)

I got 270,000 from a Pajero years ago. The only warning I got was failure (slipping). On the subject of suppliers of parts - that happens with all manufacturers. Australian made Toyotas have parts made by suppliers from all over the place and they could almost more accurately be called vehicle assemblers. The main thing they make here is bodies and engines.This is a good thing as there is work spread all over the country. The suppliers however have to make the product to Toyota specifications which are not necessarily the same as the units they produce under their own name. Hence a Daykin (spelling??) is not necessarily the same quality as one that comes out of the factory with the name of a vehicle manufacturer on it and the assurance of "genuine" part.
