Noise When Cold

Nat, try using castrol VMX80 in the g/box and t/case.

With no real mechanical knowledge, the logical reason would have something to do with balance and temperature.... So..... Something loose? Maybe one of the bolts is a bit loose on a pulley? It need only be a fraction of a mm to cause something like this. Have a look from the side and small wobble may be visible.... or vibration. Sometimes the noise coming from one place is actually transferred from somewhere else. Check the bolts on the drive shaft etc.

Just my first thoughts... Cheers Royce www.funshow.com.au

Nat, as yours is a 75 series, I would be checking the torque on the large nut, on end of gearbox main shaft. If this comes loose, and they do, the cog that drives everything in t/case will wear the spline until, in extreme cases, it will strip the spline, leaving you with no motive power.

I'll admit noise could be any where else in drivetrain, but if you've done plenty of clicks, I'd check this out.

Have noticed in cold weather that the motor often runs a bit rough too, giving impression that a valve is sticking, or it could be a bit of waxy fuel. as long as it keeps running I don't mind.

Could you get someone else to drive it while you sit in back, or stand on running board? Might highlight where it is better. Hooroo...

Do you think it is at all possible it is the brake pads rubbing on the disc as they do not completely come away from the disc and when they warm up the noise dissapears
