Bearing squeal.

fan belt perhaps?

For that sort of squeal, I generally have to get a helper to stand outside the car and listen to help me pinpoint where the squeal is coming from.

My ever loving has had considerable practice over the years.

Did you look underneath to make sure nothing is caught up, twisted around etc?

If you are in the NRMA, RACX etc you can get them out to do a diagnosis and tow the vehicle short distance if necessary, all for free.

Fact that its not in reverse makes me think its maybe not real serious, because i have never heard of a gearbox bearing squealing. Maybe a stick caught in the drive line.

Could be a loose fan belt, air con or power steering belt, they can squeal like mad, but you get that by revving the engine in neutral, and should happen in reverse.

Good hunting

Some brake pads have a tell tale device to let you know when your pads are getting down. That may be the squeal you describe.

Cracked exhaust Manifold. Squeals like a bearing and very common with that model engine 2.5TD with intercooler. You will need to look from under the car and remove some of the manifold covers.

My 100 series developed a similar noise last week, squealing and scraping noise from the left hand rear, i was outside listening while SWMBO drove,only did it in forward,not reverse. was coming from the handbrake drum in the disc. pulled it off and found a small flattish rock about 10mm square stuck in the top of the brake shoe.i had broken a small amount of material off but nothing to worry about.identify would be the first call. cheers Paul

Check for a small branch or twig stuck underneath near the tailshaft. Otherwise just jack up one wheel at a time and turn it round so you know where to look more closely.

Like the reply with the small stone I have had a similar thing happen on my Landcruiser. Drives you nuts! but hopefully it will be nothing to worry about.

Hi Bushy

Had the same problem with my 80 series on newly paved road and it was a small rock caught on the top of the disc pad. When going forward it squealed like fingernails on a blackboard. Took the wheel off and flicked it out, no more noise.

Cheers Rod

i used to get small rocks caught between brake calipers and disks ( on top ) and used to squeal like a dry bearing .. that was on a 4runner....

I,d be looking at the tin shield behind the rotor , sounds like a stone caught between the two ,they usually squeal going for ward and not in reverse . quite often if you drive in reverse for a bit it will fall out .
