Diff Whine

[Gav]

Diff has developed a whine when cruising at around 70 km/h under no load.

Will simply a change to better fluid help - or is this on the way out?

BTW - noise developed (not suprisingly) after a fair hemmering at the drags the other night.

Suggestions / experience?

my original diff did that - at 80kph it would whine like an old mole at a picnic.

over 110kph it went quiet again.

I'm almost certain crap diff oil caused mine to whine. Ended up replacing the

diff in the end.

A good oil (redline?) might fix it, depending on how noisy it is.

Worth a shot.

I am going through this right now. The diff had Redline in it - I then paid to have Shell oil to see if it would make a change - but it didn't. I think my diff is rooted.

my diff whines as well, changed teh oil an it didn't do squat!!

thought it might be the wheel bearings, how do you tell if the're cactus?

Bloody hell - an old topic of mine well and truely brought back from the dead!

Solutions:

1. Turn up the radio or fit noisy exhaust

2. Blow the motor and undertake a mamoth 2 year rebuild program by remote control whilst living/working overseas

3. Fit new CW&P gear set (opportunity to change to shorter GTS4 )
