Outer Limits 4x4 Board

Got the opportunity to do some rockhopping over some river rocks today and the noise from somewhere in the drivetrain came again to my attention.

It makes this Grrr Grr sound when idleing (up to 1100rpm) along in 2wd or 4wd and anywhere over rocks it really gets noisy as the weight too and fro's along the drivetrain.

Does anyone know what this is? The drive train is really tight in this car as it has done next to no 4wding-was a mums taxi.

thanks

Cheers fnq

didnt bash the diffs, trans or motor really hard while u were out did ya?

when the noise is there which end of the 4by is it most sounding like to come from front or back?

is it Petrol or Diesel?

evry TD42 i have ever heard orr road, or in a car park at low RPM, thends to make the same noise, i believe its more of a vibration.

Hey mate,
mine does the same.and our old w/shop ute did aswell.
apparently common.
Only happens when you labour/chugg along.!
Cheers Ian.

Mathew this car's underside has never seen the ground not even a touch! something that is bound to change
The noise is from around the general area of the front half of the gearbox.

Ozi1 it's a 4.2 diesel, yes it could be called a vibration but nothing is rattling to cause it except the engine. Yes same sound as in car parks but is VERY much louder slow over rocks.

Ian nice to know someone else who has it also(you know what I mean ) Does yours get bloody loud at times? or stays at car park levels even off road?

Would love to know the mechanism.

cheers fnq

yeah this sound is common to TD42's when labouring the engine in a big way, ive heard its best not to let it happen, there has been a thread about this before, but cant remember what it was called, so i wouldnt expect anyone to find it,

standard noise

Seem's to stay the same,or i've tuned out.
Was doing it up some hills last week.
You'll just have to go faster.

Ian.

I have a similar noise in my Patrol (auto petrol) but I just think its dirt and crap rubbing in the hand brake drum.

Cheers Mick.

All TD42 Do it standard noise, Don't Stress

Is that the noise that sounds like a heavy vibration when labouring a bit, I spent the weekend under my GU trying to find that. I thought it might have been the tab things on the engine mounts vibrating together when the motor is labouring and vibrating a bit.

I did find the gearbox and transfer breathers hanging off, a loose exhaust mount and an ants nest on the ground though.

Ok I will stop worrying, what's good enough for a GU is good enough for my 10year old GQ.

Still I would luv to know what the mechanism on which part actually makes the sound

thanks for the replys,

cheers fnq
