I have a 75 Series cruiser ute. When cold and travelling at about 10 -15 km/h there is some sought of noise coming from the driveline. I have tried to find the problem but it keeps on beeting me as when the car is at running temp. the noise dissapears. Any help greatly appreciated.

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

Nat if you suspect brake pads try gently applying the brakes with left foot while driving and see if noise changes. Col

Thanks Colin, I might check the handbrake adjustment, I have just recalled the noise seemed to appear after I played with the adjustment know on top of the handle. Any ideas on how to adjust this properly.

Nat, not sure about tojos but if you have a drum brake on the drive shaft there might be some sort of adjustment there or you may need to replace the linings as they may be running metal to metal. Col
