Diff Noise

[Sabbath']

Got a nice annoying problem with my VT II fitted with LSD.

I have a clicking noise from the rear of the car (diff area) which increases with frequency when i increase with speed. Can notice it more at slow speeds/near idle because cant hear **** over the exhaust.

Sounds like a metallic clicking sound.

Anybody come across this before? Im resigning myself to the fact it may be a case of ripping the diff centre out?

I had a similar problem with my LSD.Sounded like the handbrake or rear brake was sticking or that the diff was shot.Found a thread on here with other people with similar/same problem and it turned out that the diff oil needed changing as they suggested.It fixed the problem.Hope this helps....

Any idea what its called? Sounds interesting, my diff is noisey bought new center ages ago, never got round to puting it in!

If i could put some magic potion in to silence it, i'd be happy!!

Think the additive is called 1098 by Sturacco? It is a friction modifier and is recommended by Holden...it is already premixed in the better synthetic diff oils like Penrite/Mobil/Castrol.

I just changed to the Penrite Syn 80 and it has settled the diff chatter in my lsd...previously i hadn't used the additive and it sounded like it was going to fall out round carparks at slow speed!
