Seems there are a few members out there with Troopies.

I have a 1999 75 series with 248,000 km and in the last few months it has developed a soft low pitch whistle at between 16 hundred and 2000 revs in 1 2,3,4 gears ( maybe gearbox ? ).

Apart from that the gearbox and transfer case work well , with no obvious problems

I know it may be a difficult problem to diagnose , any ideas would be appreciated .

Thanks

Hullo Mark
Might be worth while having a look at the lcool site. (lcool.org)
There is a section for 70 series Cruisers
Only takes a short while to join (free) and you can tap into a group of very knowledgeable people
Cheers

Andrew and Jenny

I have had a look there as well.

There a few guys on this forum who seem to have good knowledge in regards to old Toyota's.

Thanks for the assistance

could be a restriction of some sort in the exhaust, can cause a whistle at certain revs

Thanks Tourboy

I Just put on a near new exhaust from my mates new Land cruiser ute ( he installed a 3' exhaust )
But I suppose it could be in the old front section .
I will suss it out.
Thanks

Did it whistle before you swapped out the exhaust?

Transfer case more then likely case hardening has came off bottom sharft and gone through box,very common.

I would have thought that if it was the transfer case than the noise would occur all the time, not just at about 1800 revs.

Thanks

Mark,
You say whistle so I am thinking it could be a leak in the exhaust/manifold. Have you disturbed anything associated with the exhaust recently? Look around the manifold and especially where the exhaust pipe comes off. They do tend to crack the weld around the flange if the support brackets have not been set right.

If it is more a whine then there is a well known problem in the gearbox/transfer which is much discussed on LCOOL. If you think it is this then do something soon as it gets more expensive if left.

Morning Mark.
My 80 serise aquired a whistling sound in all gears when driving and it turned out to be the ribbed fan belt, happy Australia day Mate.

Did the noise only start after the exhaust was done?
Is yours turbo?

Could be the sound of the turbo, quite often the whine becomes noticeable after adding a snorkel or free flowing exhaust.

No it has not got a turbo
